RE: Wi-Fi expectations/service levels and validation

[Kushner, Jeff]

It is interesting, when I started doing wireless almost 20 years ago, before 
lightweight really existed, wireless was always positioned as a best effort and 
wired was definitely the way to go if a reliable connection was required. 
Today, wireless has become a replacement for wired in many locations, but our 
success is almost our downfall, the proliferation of wireless devices and 
interferers makes the delivery of quality wireless connections a constant 
battle. Not to mention the wide variety of client devices. And lets not even 
mention the manufacturers and issues with the firmware and software. I guess we 
can call all the aggravation a form of job security.

Hi All,

Coming out of a very rough fall semester start that left many of our users 
suffering with "bad" Wi-Fi, we've since (understandably) been asked what 
constitutes "good" Wi-Fi.  We have not previously published information to our 
community on what they should expect or on how they can validate those 
expectations.  Does anyone have any knowledge articles or links they could 
share?

Thanks!
Dave

The 9800 does have a conversion tool for the aireOS controller configs and does

Even if building from scratch, running the existing config through the tool may 
help in understanding how all the pieces work, including the equivalent 
commands between the two.

When building from scratch, it can be helpful to forget about what you had, and 
treat it as a different vendor product. It’s a rather radical change, but far 
more powerful, and despite many will initially ignore the built-in wizards, 
they are pretty powerful.

That is an interesting solution. Our university is very concerned about

A few years ago we had to "light up" a couple of parking lots. The light poles 
there are on timers, so there is no power during the day. Trenching was cost 
prohibitive as well.

We ended up setting up a mesh from a nearby building to send data to these two 
APs. And for power, we used continuous power bridges from Solis Energy. At 
night, the light circuit provides power (which is 240v) to the bridge, which in 
turns provides power to the access point while at the same time charging up a 
battery. Once power is disconnected, the battery kicks in and powers the AP 
during the day. Only issue we had when they were configured was they gave us 
802.11af injectors instead of 802.11at ones, which was required for the AP to 
work.

It’s something to verify though.  The problem with bollards is that combined 
with the light poles, it makes the area very busy with vertical poles.  It’s 
supposed to be an inviting area, not one that looks like a jail (or crib).



Thanks though.  All of these are being added to our “double check” list!

In my experience (YMMV) light poles have photo cells which would prevent proper 
power from being fed to your APs during the day. In my case, it’s even worse, 
there is one “loop” that feeds the power to all poles on campus, so all poles 
light up at the same time, I cannot only power one up, say because I have an AP 
on it but not on the others. And we’re not even talking about convincing the 
power people to let you put something on “their” pole...



Hanging from roof is just a huge hassle, too high anyways and the cost in 
wiring in addition to the loss you would get even using LMR600 would be too 
much trouble IMO.



So either bollards or some kind of a pole or even a skinned building-side 
solution could be best. If you have bus stop enclosures that are heated/cooled, 
maybe they could help you cover the area?

We had to upgrade to 8.5.161.4 due to issues we experienced with the 8.5.161.0. 
We had a problem where an AP would allow clients to associate but they would 
not pass traffic. The new code, as recommended by TAC appears to have fixed the 
issue, we have been running it for 36 days. But we won’t know for sure until we 
get our normal client levels back with the return of students to campus.

Hello everyone,

We are running code 8.5.135.0 on one of our WLC 8540 pair. We can’t go past 8.5 
because of presence of 3500 and 3600 model Aps which are not supported beyond 
code 8.5.

What code you are running in 8.5 train and how satisfied you are with it?

Is anyone running code 8.5.161.0 recommended by Cisco TAC? How stable is it? 
Have you encountered any major issues in your environment?

Has anyone tried 8.5.16.4 (escalation code)?

Thanks in advance for your responses 😊

Do any colleges have any workarounds or solutions for this?
