Aerohive Networks is offering this free WLAN Troubleshooting and Design Guide authored by CWNE #4 David Coleman and CWNE #7 David Westcott. This is actually chapter 12 of the Certified Wireless Network Administrator Guide (CWNA).
We would recommend buying the CWNA Study Guide to anyone who interested in, or has the responsibility of managing, WLAN. Put it on your shelf next to your copy of “Microsoft Exchange for Dummies” 😬. Read a chapter a day and you’ll be amazed how much you’ll learn and come to understand about how wireless works.
Either way, take advantage of this free download and the generosity of Aerohive Networks. Way to go guys! 👍
Short and SWEET. Just the way I like it. Why wireless access points are not “WAP"s. They’re just "AP"s. — CHECK OUT http://banwaps.com
Here is one reason not to believe someone when they say the wall is “just drywall” pic.twitter.com/IVlqLRPD2V
— Aaron Scott (@wifidownunder) July 13, 2015If you’re doing “Predictive Surveys” (really “Predictive Models”) then you owe it to yourself to survey your location and make sure your walls are what you think they are.
If someone is “designing” you a WLAN and they don’t take the time to gather as much real data from the deployment site - you more than likely not going to like the results.
Look, I don’t WANT to judge, but I’m guessing this is probably not something you want accessible from your Guest WLAN.
This coffeeshop has Airport which is fine.
Having the admin password be the same as the PSK?
Not so much. 👎😱
Here`s the dirty little secret of 802.11ac “Waves“ 1 AND 2: You`ll most likely never see those Unicorn Gigabit speeds that are plastered on the side of every box of every 802.11ac access point. ¯\_(ツ)_/¯

Mas metal!
EVERYONE, Wi-Fi and METAL ARE NOT A GOOD MIX!
So, if you’re wondering why your hotel wi-fi sucks it’s probably because of this.
By the numbering scheme it looks like each of these is an individual AP broadcasting its own SSID. I can’t even imagine how bad the Wi-Fi is, and I don’t even want to think about having to manage all these individual access points! 😱

There are plenty of certs out there, but you probably don’t want this one!
I recommend CWNP (Certified Wireless Network Professional.😁
Some things are just out of your control. When a squirrel needs a new hiding place.
Acorn Attenuation! 😱
Went to enjoy a ball game. Overheard someone complaining that their ticket scanners weren’t working right…..*sigh*

Again with the APs in hallways?
EVEN WORSE they are on the walls (incorrectly installed because of the antenna pattern) and THEY ARE FACING EACHOTHER! Even if CCI weren’t an issue (it is) ACI (Adjacent Channel Interfernce) is more than likely gonna be an issue.
This is repeated about every 50ft down the halls.
Can you imagine having someone screaming in your face EVERY SINGLE MINUTE OF EVERY SINGLE DAY?
All one can do at this point is ¯\_(ツ)_/¯.

Yes, it MATTERS how the antennas are positioned. In this case, dipole-omnis, they should all have the same polarization, and be facing the same direction - down.
Dipole-Omnis have a doughnut shaped pattern. So, if your antennas are horizontal with the ceiling, you essentialy have a doughnut-shape up and down (narrow). Set them down (perpendicular to the ceiling) the doughnut is now flat and wide, giving you much larger coverage area.

Xirrus v2? 5G+5G+5G+2.4G tied into one antenna, indoors, no HD areas. #ACI but no adv that I can think of. @Blackbox pic.twitter.com/xLJuzMdxgO
— Devin Akin (@DevinAkin) May 28, 2015Three APs on ONE antenna.
Do. Not. Do. This!
This isn’t even a DAS (Distributed Antenna System)! It’s right there! There’s nothing distributed!
You’re not gonna get more capacity!
All you’re gonna get is $$$$ out of your checking account to the salesperson hat sold this.
Oy.
CCI? What CCI?
EACH AP HEARS EVERY AP!!!!!

Yet another example of why your should NEVER (If you can at all avoid it) install APs in the hallways for client access in rooms.
You can see in the lower photo that all the APs hear ALL the other APs. You’re essentially creating a funnel for all the RF to propagate freely & easily. This causes high level of CCI and probably more importantly: THE WIFI IS NOT WHERE THE CLIENTS ARE!

Let’s securley, secure, our APs.
You know - for security’s sake.
“When brackets are just not needed.”
—If you’re gonna spend money on a pricey peice of gear, maybe you might want to install it properly.
You know for appearances.
And security.
And so the pricey peice of gear don’t break when it rains and the wind blows it off the roof.
I’m sure this is grounded to.
And that Ethernet connection looks thoroughly waterproofed.
Just sayin’.
