VenVolt 2- Power to the (Survey) People

Hello wireless friends,

My name is VenVolt 2. I’m soon to be sent by the excellent folks at Ventev to assist you with your wireless site surveys in those situations where you need to power an access point. If you caught Mobility Field Day 6, then you saw Ventev Product Line Manager Chris Jufer introduce me… it’s a little daunting being shown off, but I can handle it. I was born for this role- some of you probably know my dad, VenVolt 1:

VenVolt 1

The Old Man still has his own magic, and quite the following. But we all know the drill… everything changes. If you get lucky, the change is for the better- and that’s where I come in. Here’s my profile pic, in case you missed it:

VenVolt 2

I’m sleek, I’m sexy, and I got the juice. Ventev learned a lot from my pappy, and I’m proud to be his follow-on in the product line. V1 uses Lithium Iron Phosphate batteries, but I’m LiPo, baby! V1 was also a bit of a porker at 4 1/2 pounds, but I go a svelt 2.2 pounds for you less macho types. And I’m rated at 26,400 mAh- just at the edge of legal airline carry-on. I charge in about 3 hours, and will power an AP for around 6-8 hours, depending on model. I could go on, but I’m already bragging a bit so maybe I’ll just show you some specs.

But first I gotta tell you- they are shipping me with this very cool bag!

You can already see the benefit there, I’m guessing. It’s not just a protective case for my handsome finish, it’s also an accessory at survey time when you need to attach me to something. (Think safety, says I.)

Now back to some specs and application notes from my demo reel. I think you’re gonna like what you see… Look for me around late September or early October of this year. Meanwhile, feast your eyes on this goodness:

VenVolt 2 by Ventev, ports, etc

I trust that you dig it? Of course you do. Because you’re smart and good-looking, too. Or maybe just smart, as I take a second look. But what matters is that I’m (almost) here for you, and you’re gonna want to make sure we get together for your Q4 surveys. I’ll see you then.

Hugs,

Ventev’s VenVolt 2

Mist Systems Has an Advantage- but Also Gets a Yellow Card

Now the race is on
And here comes pride up the backstretch
Heartaches are goin’ to the inside
My tears are holdin’ back
They’re tryin’ not to fall
My heart’s out of the runnin’
True love’s scratched for another’s sake
The race is on and it looks like heartache
And the winner loses all

-Sang by George Jones

Though events like Mobility Field Day 6 may not be typically thought of as being contests, I can only imagine that those participating from the vendor side feel the competitive heat. The spotlight is on, the dollars to participate have been spent, the camera is rolling, and there is a tight window to differentiate your offerings and approach from the rest of the pack- all while a group of delegates interrupts your presentation and peppers you with questions. Success is measured by Twitter conversations, blog posts, and ultimately sales numbers. As a long-time Field Day participant from the delegate side of the paradigm, I can’t help but think that Mist still has an advantage of sorts when they present. I’ll explain that here, but will also point out that cockiness can sometimes cost you based on one comment made by Mist during MFD6.

The Mist Advantage

Mist was a late-comer to the mature WLAN industry, being founded in 2014. But those involved with starting the company are hardly newcomers to the game, and they have done a good job of making a start-up extremely relevant in a competitive market. I’d dare say they have been disruptive. And of course they were bought for a zillion dollars by Juniper. So what is The Mist Advantage when it comes to these presentation-oriented events?

Their short history.

Sure, they have decent technology, and even if you get tired of AI-everything in the company’s messaging, that is obviously working for them. But it’s what Mist DOESN’T have that’s just as significant to their appeal: they don’t have years and years of messaging fog and technical bloat to overcome. Their story is still fresh, and when you sit down to listen to them, your mind doesn’t involuntarily think about their long history of bugs, frequently changing “campaigns” and named networking frameworks, and all the ways customers have been frustrated with their licensing and support. Because… that history doesn’t exist yet.

The irony with Mist is that many of their key corporate players have come from companies that DO suffer from the effects of simply having a long history, and were likely personally responsible on some level for at least some of the baggage left behind at the companies they left. Such is life in Silly Valley, and I applaud anyone who recreates themselves and learns from the past.

How long will the Mist story remain untainted by it’s own longevity? This will be an interesting question to watch play out. But I have yet to hear of any customer switching FROM having a Mist WLAN to a legacy vendor, and the continual development of products and underlying magic is impressive on Mist’s part as evidenced by what you’ll see in the MFD videos.

Yellow Card Thrown

I recommend that anyone interested in Mist or wireless networking in general watch the Mobility Field Day videos from the company’s presentations. These folks know their stuff, and the enthusiasm is palpable. But I do have to call out one thing that didn’t set well, and sounded maybe a bit beneath the Mist Team.

The day before Mist presented, Aruba Networks showed their Wi-Fi 6E AP630, a fairly ground-breaking offering that brings real-world networking in new 6 GHz spectrum to the wireless space. For months now we’ve all been giddy about 6 GHz being made available for use by the FCC, so Aruba giving the world an early 6E AP and being able to show what it does in a controlled environment is a good thing.

I’ve heard every single vendor so far at Mobility Field Day 6, including Mist, say things like “you gotta start somewhere” or “this is just our first step towards blah blah blah”- reasonable utterances for companies who need to innovate or wither. So when the topic of 6E access points came up and Mist seemingly slighted Aruba for putting out a lowly 2×2 6E AP while Mist has nothing to show yet in 6E, it seemed a bit low-brow. The comment was noticed by a few other folks out there as well, and I’m curious your take on this if you happened to catch the dialogue.

Aruba Said the Right Words Regarding Dashboards

I wanna be a dashboard ranger
Live a life of guts and danger
I better stop before this song gets stranger…

Ah, dashboards. We got ’em these days, in quantity. We got so many freakin dashboards we need a dashboard to keep track of our dashboards when it comes to networking. But beyond dashboards, we got… AI.

That’s right- we got Artificial Intelligence, baby. And it’s teamed up with Dashboards, Inc. to make sure we have ALL KINDS OF STUFF to worry about. And maybe, if we’re lucky, some time those alerts will actually be actionable…

If you haven’t figured it out yet, I’m dashboard-jaded. I’ve seen many dashboards from market leaders that cost a fortune (they gotta make money, no fault there), that are fraught with Chicken-Little noise that is so overwhelming and uncorroborated by any other practical metric that they become one more Glass of Pain that gets ignored. Will AI help that? The answer will depend on how that AI is coded- like does the team behind the AI actually GET that endless petty alerts aren’t really a good thing?

Which brings us back to REAL intelligence… and Aruba Networks at Mobility Field Day 6. In particular, the presentation on what Aruba calls AIOPS– their version of system monitoring, root cause analysis, system adjustment, etc. This is something all the major vendors are doing these days, and all make sure that “AI” is sprinkled liberally in the marketing so you know that you are good to go. Unless you’re not, because the AI flags a bunch of stuff you don’t care about that takes you away from real work.

But Robin Jellum at Aruba said something profound in it’s simplicity as he presented on AIOPS… The exact wording escapes me, but Robin alluded to the fact that we all get bombarded with data. There’s no shortage of it in today’s network systems. But turning that data into MEANINGFUL alerts versus just lots of red and yellow dots to get lost in is the challenge, and Aruba recognizes that gratuitous, copious amounts of alerting on transient stuff does no one any good.

As a customer, I don’t want to buy ALERTS by the pound. I want to buy INFORMATION that comes from my data. It’s nice to hear Aruba recognize the difference. Time will tell if AIOPS can deliver.

Interfering Personal Hotspots- Beyond Simply a Technical Issue

After 20-some odd years in the Wi-Fi business, I can safely say that I both love and hate personal wireless hotspots. Before I get into all that, let’s go back in time. If you want some zesty background, here are a few easy, compelling reads written by me from the way back machine:

If you don’t want to review the above links, here’s the poor man’s executive summary:

FCC: Don’t use de-auth frames- that equals jamming (depending on which one of our own definitions you stumble across). Selling jammers is illegal. We let Wi-Fi vendors sell illegal jammers because they provide tools that do de-auth. But that is illegal. You can’t sell jammers except when you can sell jammers. Confused? Shut up, or maybe we’ll fine your ass for our lack of clarity. Our annual fund-raiser is coming up- how’d you like to “donate” several thousand dollars?

Hotspot Makers: We use only the highest power and some really cocked up channel selection algorithms to ensure your device delivers the absolute finest in RF interference to the Wi-Fi environment you are sitting in the middle of.

Wi-Fi Alliance: BUY MORE WI-FI GEAR! FAT CHANNELS! GO TEAM! CRANK UP THAT POWER! WORK IT, YOU SWEET THANG! WE ARE AWESOME, JUST ASK US! IGNORE ALL THE STUFF WE SHOULD HAVE BEEN DOING FOR THE LAST 20 YEARS.

Network Customers, WLAN Admins: WTF?

It all makes perfect sense if you don’t think about it.

The Technical Frustrations

Anyone else in the biz knows that hotspots can be annoying, or they can be WLAN-killers. It all depends on the day, the device, the location, and the density of the WLAN where those hotspots are fired up. You can only play so many frequency-stomping games with spectrum, then physics shows through and Wi-Fi sucks for everyone until the contention is eliminated. This is the technical side of hotspot frustration.

And nobody of title has done a shittin’ thing to improve the situation- not the FCC, not the WI-Fi Alliance whose members make all of the devices that step on each other, not anybody. Everyone is in it for themselves… (Soapbox moment brought to you by the good folks at Shamwowsers & McKracken, LLC).

Ah well.

The Cultural Component to the Whole Mess

Cell phones and Mi-Fi devices have come soooo far since WLAN administrators first played whack-a-mole with hotspot-induced network issues. Data plans have also evolved, to the point where many of us are walking around with dual-band, unlimited data hotspots in our pockets ready to put into service at the slightest notion.

Let’s turn to rocker Ted Nugent for his take on the situation, as written about in his mega-hit “Free For All”:

Well looky here, you sweet young thing: the magic’s in my hands
When in doubt, I’ll whip it out. I got me a hotspot- dual-band
It’s a free for all

Or something like that… It ABSOLUTELY IS a free for all. That’s the culture right now. If I can’t get on the business network because I don’t know how to configure meself for 802.1X, I’m gonna WHIP IT OUT, Nugent-style, and get myself off to the Internet. The business Wi-Fi can suck it, and how dare you expect me to open a trouble ticket to get help with your 802.1X noise? THE MAGIC IS IN MY HANDS. Any collateral damage is NOT MY PROBLEM.

So what if your stupid police cars can’t transfer dashcam video because of interference? Why do I give two figs if your expensive Wi-Fi locks and clocks are acting up because of my RF pride and joy? Spare me the lecture on how your wireless VoIP handsets are getting walked on… Maybe YOU shouldn’t be using Wi-Fi-equipped medical devices. IT’S A FREE FOR ALL, DID YOU NOT GET THAT MEMO FROM TED NUGENT?

Hate ’em, Love ’em

Yeah, hotspots are a big fat PITA. They really do create problems. Some are dual-band, high power beasts that insist on obliterating your WLAN, while others seem to have a little more common sense and lower power built in, but in dense WLAN environments it still gets ugly.

But I’m here to confess that I too hear their siren song.

I get WHY people fire up their hotspots. At hotels, at camp, while troubleshooting systems that have potential ISP issues and so on. My phone’s hotspot gets it’s share of exercise, and I can’t imagine not having it available in a number of situations. But as a WLAN professional, I have the knowledge and (usually) the discipline to not hose up someone else’s WLAN with my hotspot when I’m at their place of business. Most people- not so much.

We’re way past the opportunity for THE INDUSTRY PLAYERS to responsibly to educate end users on why hotspots shouldn’t just be whipped out Ted Nugent-style. So we’re stuck with the problem.

Suck it up, Buttercup

What really sucks about all of this is that WLAN components are only getting ever more expensive. The tools that are used to design and support WLANs are only getting more expensive. Collectively, the security stakes in almost all WLAN environments are only getting higher. We can pump endless dollars and man-hours into delivering really good Wi-Fi, yet hotspots can lay waste to parts of our infrastructures, and there isn’t much anyone can do except to ask the offender to put them away, if we can pinpoint them and get them to listen to our appeal that they think of their fellow man…

Strange times, says I.

Linksys Leverages Tanaza for Cost-Conscious Cloud-Managed Wi-Fi

You’ve heard of Linksys, everybody has. But Tanaza? Is that an energy drink? No, but it is what fuels Linksys’ latest go at cloud-managed Wi-Fi. Let’s get the Tanaza thing out of the way first, then we’ll talk about what Linksys is up to (if you’ve had with expensive vendor license paradigms, you’ll want to read on).

Tanaza Explained

Tanaza – Logos Download

Tanaza is a cloud-managed networking platform based in Italy, I’ve been tire-kicking and following the evolution of the Tanaza system for a while now, Here’s a blog I wrote on Tanaza, to get you started. I like the company, their people, and the UI. As an enterprise WLAN guy myself, I sometime have to stretch my mind to get the appeal of a company that (so far) only manages Wi-Fi and not “the full network stack”, but once you get that it’s easy to appreciate Tanaza’s effectiveness. Recognizing a company’s Wi-Fi as the thing that many SMB customers interact with the most with, Tanaza makes providing well-managed and feature-rich WLAN environments easy for single sites or distributed locations likely served by MSP types or savvy in-house staff that need the most for their precious network budget dollars.

Linksys Cloud-Managed Wi-Fi 2.0

As a reminder, Linksys is part of Belkin, which is part of Foxconn. You of a certain age may be pre-disposed to think of Linksys as a home router vendor, but the company has long since evolved to having business-grade products in several spaces. With its latest strategy for cloud-managed WLAN, Linksys replaces it’s old in-house magic with Tenaza’s very polished dashboard and management framework and pairs it with a so-far modest handful of decent indoor 802.11ac wireless access points.

So what is the actual news here?

Tanaza has the cloud-management thing down pretty well. The case can be made that Foxconn/Belkin/Linksys using Tanaza’s framework validates Tanaza’s suitability for the SMB/MSP masses. The Linksys empire includes manufacturing, support, various channel relationships, and the ability to capitalize on Tanaza’s native cloud goodness to offer a decent SMB solution at compelling prices. And what makes those prices compelling? Probably the biggest selling point is that no licenses are required when you compare to other cloud-managed solutions. In my opinion, many of the bigger guys have gotten so license-happy they have priced themselves out of the SMB market.

Good Stuff, But Is It Enough?

Linksys Cloud Management 2.0 promises unlimited scaling (again, think MSP), easy pre-configurations and new access point adds (think Meraki-style), and has a good road map for options that will help customers to either directly or indirectly monetize their guest WLAN environments. All that sounds good when you can get it for cheap with no licenses, and I will say that the Tanaza access point I’ve been running works well. But I also can’t help but think that sooner or later “cloud managed Wi-Fi only” is going to be an issue for some potential customers. Even Open Mesh, before they were acquired by Datto, had a pretty effective cloud managed switch and edge router offering to go with their wireless APs, as does Ubiquiti- who is always the elephant in the room in this space. An outdoor AP option with external antenna capabilities would also be nice.

Its Time to Let the WAP Rage Go and Move On

It’s an often-repeated cycle: someone says WAP in reference to a wireless access point, while those of us who consider the device to be an AP (no W) recoil viscerally. Maybe a lecture ensues about the PROPER way to refer to an WLAN access point, and it’s not uncommon to get a lot of YEAH WHAT HE SAID! and maybe some DAMN RIGHT! thrown in as we all work ourselves up to a froth over this oddball, seemingly important topic.

I said “seemingly” important.

Except it’s not. It’s actually kind of snobby, and kind of foolish. Don’t we have bigger things to worry about?

Those we quibble with in the epic WAP vs AP Thousand Years’ War often come from different backgrounds, where they learned that WAP is correct, prudent, and A-OK. One example- I work with a really smart BICSI-certified RCDD (that’s Registered Communications Distribution Designer, kind of like the CWNE of the wiring world) and guess what? He learned that WAP is a standard term on his professional journey. BICSI’s ICT Terminology Handbook uses WAP no less than 14 times!

Then there’s the WLAN market leader- Cisco. “WAP” occurs in enough Cisco documentation to be considered a valid term, at least by me. An example:

Are you AP-Purists feeling silly yet? I fully realize that this is one of those religious debates that polarizes people. Some of us will NEVER stop clinging to AP is good and WAP is evil because the notion has become ingrained in the fabric of their WLAN professional beings.

Whatever.

Wikipedia says both are OK. If you Google <Wireless Access Point WAP> you’ll find well over a million results, many from vendors who call their stuff WAPs.

This shouldn’t be one of those triggers that make us drop what we’re doing to school our fellow men and women about what they SHOULD call a wireless access point, yet it is. It doesn’t make us look smart or superior. Au contraire, it makes us look kinda petty, closed-minded, and dare I say silly.

Just stop it already.

Dipping Toes in the Consumer Gear Pool- Netgear AC2300 Wireless Router

I don’t frequently kick tires on consumer grade gear, but occasionally it is good for us Enterprise folks to go that path. Certainly, this space continues to advance- as measured by features offered, complexity under the hood, and promises made that often can’t be kept.

This is an interesting router, and I’ll try to approach my narrative from the consumer-centric focus. That being said, even the consumer wireless space needs to be handled by vendors with common sense. That is lacking in spots with this router, but likely no more so than with it’s competitors who also fixate on grand performance claims over substance. Sigh… the data sheet for the AC2300 is ambitious, to say the least.

Why so Many Model Numbers?

I have NEVER understood this about Netgear (and others in this space). On the box, it’s the AC2300. On the vendor product page, it’s the R7000P, as well. Then when you access the admin pages on the router itself, it becomes the RS400. Just kick me in the groin.

Getting Started, Choices
I’m old and stodgy. I just want to connect to the router, and start poking around. But Netgear would prefer that you download the Nighthawk app, which I did. But to run said app, you need a Netgear account, and in my opinion they want too much personal information. Nyet says I despite the fact that the app might be somewhat handy. Negatory on that. Also, the same account is needed to activate NETGEAR Armor which is a subscription-based security suite (Netgear gives you three years free with the router purchase). Given that I don’t plan on making this eval unit my daily driver, I’m going to pass on Armor- but here’s some interesting chatter among IT folks about it.

I opted to simply connect to the device over Wi-Fi, using the password provided on the router, and head for good old 192.168.1.1 admin page. I also opted not to bite on another subscription- Disney’s Circle parental controls, which were offered one click in . If I was at a different place in life (my kids are grown and live elsewhere), I may welcome something like Circle but would need to evaluate.

Netgear touts the AC2300 as a CYBERSECURITY router, which is OK. Even without the app, Armor, or Circle there are some decent security-oriented features available, as you’ll see in the screenshots.

As a Switch/Router, Looks Decent Enough

See the screenshot dump at the end- you’ll get a sense of the usual offerings that come in better model routers. VLAN support, firewall functionality for device access, URL blocking, protocol controls, etc are handy, and the switchports are 10/100/1000. Also USB3 connectivity to storage or whatever floats your boat. Nothing earth-shaking, but a well-rounded feature set.

Wireless Performance Good- But the Approach is Maddening

It’s funny that the data sheet mentions “interference avoidance” in at least one spot, but your neighbors might not agree given that the AC2300 comes up blasting away on 80 MHz wide channels in 5 GHz (gotta be so to bring the jigabits!) and squatting on channel 9 in 2.4 GHz. How about the power level? Out of box it’s 100% on both channels. 100% of… well, something. but mere mortals aren’t privy to such details. I am not a mere mortal hover, and so I know where to find the power output levels for this router – if you know what the values mean, you’ll agree that this router is quite the flamethrower. Depending on where it’s used, you may not be able to get the power LOW enough.

For some reason, Netgear also decided to expose a couple of settings you can ruin your own day by manipulating wrongly…

Some things are better left hidden, says I. But it is nice that you can schedule the radios for on/off as desired.

I’d Buy It, and Then I’d Get Wise About Configuring It

If I was shopping for a normal consumer router, the AC2300 would be a good candidate based on booming radios and decent features, with or without the subscription stuff and Nighthawk app. It’s a nice enough looking router. The wireless defaults are ugly, though and  can do more harm than good. At the same time, consumer grade stuff is set up out of the box to THEORETICALLY meet the bold promises made in marketing (good luck getting 1625 Mbps in 5 GHz out of this or any 802.11ac 3×3 router) on the assumption that all consumers operate in their own little vacuums.  

 

 

 

The “Not to Be a Jerk, But…” Mist #MDF5 Blog

I write this piece fresh on the heels of Day 1 of 2020’s Mobility Field Day 5. Mist (Now a Juniper company) talked for about six years yesterday, and it was fairly riveting, end to end. It was one of those marathon sessions that needs a little time to settle in your brain before you can resolve it, figuring out what you actually liked to hear and what maybe raised some red flags. Let’s talk about those red (well, maybe a pale red, sorta orangey-pink) flags that sprouted in my mind as I slumbered on the whole thing.jerk

Mist Systems has had a fantastic run as a late-comer to a competitive industry filled with incumbents. That’s not easy, and their AI-inspired story has served them well. Now, we see the company moving i’s own cheese, and I can’t help but think about maybe  a few areas of concern.

  • Mist is no longer its own little WLAN product line bubble. Mist started off as a wireless-only product line. That let it focus on one discreet area with all of its development and quest for excellence. Sure, AI has been a key ingredient. But AI is not a magic wand. Just because you use it, doesn’t mean you have the Golden Ticket forever. NOW, Mist is spreading its methodology into the Juniper LAN side of its new house… the bigger you go, the more places there are for things to go wrong. The more opportunities there are for code bugs…
  • Mist has finally introduced a respectable AP product line. Again, Mist has had the luxury of not offering many APs to date. Life has got to be easier on the development side when your product set is smaller, I’m guessing. We see it frequently from other vendors- certain model APs are prone to issues and bugs. Will Mist bump into the same sort of customer-facing shame now that they have some diversity of AP lineup? Or will their promised self-debugging whizz-banginess eliminate that as a potential? Time will tell.
  • The um… well… uncomfortable thing to mention. I have the utmost respect for Mist’s senior leadership. Their results to date with injecting the AI/higher reliability story into an industry often fraught with overpriced buggy code suck speak for themselves. However- some of Mist’s senior folks come from that world of buggy code suck. They helped to author the very realm they now take potshots at. I mention this only to make the point that nobody is  perfect with a perfect past, and that history sometimes repeats itself. In the buggy code suck world, complexity only exasperates the buggy stuff, and Mist, as an overall operational paradigm, is very much becoming more complex as it matures. Ergo… more opportunities to stumble? Hopefully, they can keep it on the rails and not fall victim to the past woes that some of their own Bigs have at least partial ownership of elsewhere in the industry.

That little burst of sunshine aside, it really was a thought-provoking session. See it for yourself here, and feel free to leave me a comment below.

 

Intuitibits: New Name, Familiar Tools

wifi_explorer_pro_largeI’m guessing that if you gathered 100 wireless network engineers in a room, at least 50 of them would have the WiFi Explorer Pro application on a Macbook. And I’m also guessing that like 35 of those 50 would actually use it frequently in their WLAN support and troubleshooting duties. It’s a great tool, written by a talented fellow. And that’s where the story line of this blog begins.

Adrian Granados- THAT Adrian Granados

Let’s clear something up straightaway. THIS Adrian Granados will kick your ass:

boxer Adrian

While THE OTHER Adrian Granados is the genius behind some damn good wireless tools:
Do-You-Have-a-Mac-Adrian-Granados-WLPC-Phoenix-2018

I would recommend not confusing the two. I’d also encourage you to say hello to Wireless Adrian if you ever get the chance at an industry event because he’s just a nice gentleman.

And… he wrote WiFi Explorer Pro.
And… he continually improves it.
And… he wrote a bunch of other excellent tools. Like Airtool, Transfer, and WiFi Signal.

Introducing Intuitibits, Headed up by Adrian Granados

Intuitibits is a new company, with Granados at the helm. In their own words:

We create the most intuitive, easy-to-use Mac tools for home users and wireless professionals looking to monitor, validate and troubleshoot wireless networks.

I can vouch for that description, as I’ve used these tools in a number of settings. They tend to hit that the elusive sweet spot where you don’t have to be a WLAN expert to get value from them, but they go the distance for those of us who are experts. I recently sat through the Wireless Adjuster course, where Intuitibits’ WiFi Explorer Pro features prominently in the course materials. I was impressed with WiFI explorer before the course, and was even more so after having it’s deeper capabilities revealed during the training.

Possibly the Best Value Among WLAN Tools Out There

Intuitibits’ products are effective, for sure- but they are also priced for all. With affordability in mind, nothing is lost for support (the rare times you may need it), and it’s not uncommon to see WLAN pros using these tools before their more expensive ones in troubleshooting.

I wish all at Intuitibits good fortune as they begin their journey. And I can’t wait to see what’s next in the product line.

 

 

 

What I Took Away From the Wireless Adjuster Course

This course comes from Divergent Dynamics, taught by none other than Devin Akin. I have been following the story line of Wireless Adjuster since before it was unleashed, and here is some background if you have any interest:

Now that I have actually sat through the two-day course myself, let me share my impressions.

Wireless Adjuster Fills a Need

There is vendor training out there for wireless networking, and there is the excellent Certified Wireless Network Professional (CWNP) program (reminder that I am CWNE #200 and current member of the CWNE advisory board). But I have yet to see a really good, practical, hands-on training course that looks to equip a broad cross-section of wireless troubleshooters with the mindset and experience to use tools that almost anyone can afford to find perhaps 90% of likely WLAN-side problems.

Wireless Adjuster Complements Other Courses

Regardless of your past training and proficiency with wireless analysis (like CWAP), survey tools (like Ekahau) and basic foundational knowledge (vendor training, CWNA), Wireless Adjuster re-enforces and introduces some pretty key best-practice (and exceptions to best practices) philosophy for a range of WLAN situations. Combine what you get out of Wireless Adjuster with what you already think you know, and you’ll be living larger as an analysis professional, I promise.

Wireless Adjuster Shows Just How Powerful WiFi Explorer Pro Really Is

WiFi Explorer Pro is already widely appreciated among WLAN professionals as an easy-to-use, huge-bang-for-the-buck WLAN analysis tool. It doesn’t NEED to be the main tool used in Wireless Adjuster to gain recognition, but the way it is used in the course will make you appreciate WiFi Explorer Pro even more. Devin does a nice job introducing aspects of the tool you may not be aware of, and uses it as a bona fide troubleshooting suite that competes with any tool out there. When you consider the integrations supported with MetaGeek’s dBx adapters, WLANPi, and other external devices, it’s fairly mind blowing that WiFi Explorer Pro can be had for under $100. To me, this is the best value out there among WLAN support tools.

Wireless Adjuster Exposes Just How Defective the WLAN Standards Are in Spots

I would love for anyone involved with developing 802.11 standards and the entire Wi-Fi Alliance staff to sit through Wireless Adjuster. Throughout the class, you’ll see example after example of how optional parts of the various standards cause a lot of performance problems in various WLAN settings. You see real-world examples of the cost of the IEEE 802.11 groups being hung up on backwards compatibility. You learn why many of the sexy, hyper-marketed aspects of 802.11, .ac. and .ax sound great in promotional material, but flat-out suck in the real world. Devin finds fault with none of it, and is far more of a gentleman about it than I am. He methodically and objectively guides you through this odd reality through real live examples that you analyze for yourself.

Having taken Wireless Adjuster, I’m now even more taken aback than I have ever been  about how out of sync with reality the IEEE 802.11 folks, the Wi-Fi Alliance, and many WLAN vendors are with real-world WLAN performance. It’s pretty freakin’ unreal, says I. Don’t agree? I’ll fight you, and I’ll fight dirty.

Wireless Adjuster Is Fairly Captivating

I will freely admit that I am a far better instructor than I am a student. I have a recognized track record of being good at teaching, dating back to my time in the US Air Force instructor school. But put me on the other side of the equation and I get bored easy as a student. I daydream. I doodle. I multitask, and do a fairly poor job of it. But for the almost twenty hours of Wireless Adjuster time, I was pretty much riveted. The discussion was fantastic, the examples are relatable, and even though I’m a certified “expert” I learned once again that I don’t know it all. Wireless Adjuster commanded my attention (despite taking the course remotely), and I finished the training with a todo list of things to go examine on my own networks.

Final Word: Time Well Spent

When it comes to technical training, I want VALUE. I don’t want to spend a day getting a half-hour’s worth of actionable information. Wireless Adjuster hits that sweet spot where newer wireless folks and vets like myself can both benefit greatly from the materials, the exercises, and especially the discussion throughout the course. I’m glad I took the class, and I highly recommend it.
