Re: [EXTERNAL] [WIRELESS-LAN] protecting AP's in a gym?

[Mallon, Jason]

Hey Tim,
We are using something similar to what is in the link, and from what I can tell 
it does a fairly good job.  We have an AP right behind one of the goals, so I 
know it has been hit a few times.

Wireless managers,
  We have some Aruba 325 AP’s in a gym and I am wondering what some of you use 
to protect them from physical damage such as a softball ball, etc?  Do you use 
some sort of a cage?  If so what?  If it uses metal, does it interfere with 
your signal strength?

Subject: [EXTERNAL] Re: [WIRELESS-LAN] Client roaming
We’re an Aruba shop and have noticed similar behavior.  We’re having more 
incidents of intermittent connectivity issues this year than in previous years, 
and most of those clients are making questionable roaming decisions.  It’s been 
really prevalent with iOS and MacOS.  Much less on Windows and Android.  
There’s always been problems with picking a good radio when those devices first 
connect, but, historically, once they were steered to a good 5GHz radio they 
stayed there.  They’re not staying there this year.  We haven’t figured out why.

Wondering if anybody else is seeing this.  We currently have devices doing a 
lot of roaming between 5 and 2.4 radios, especially in the dorms.  I would not 
think anything of it normally, but they are moving from a -52 to -58 on the 5 
radio to a -75 or worse on the 2.4 radio.  This doesn’t seem to matter what 
SSID they are connected to.  Band select is enabled on all SSIDs.  We are 
running Cisco 8540 WLCs on 8.10.130.  Most of the complaints are coming from 
the dorms, so I am not sure if it is happening on our other controllers with an 
older code level.

Maybe it is just us, but we have lots of places where a 12dB delta is hard to 
achieve when designing for dual 5G radio coverage at -65 dB.  Clients end up 
skipping an AP (or two) before actually roaming.  Not to mention use case and 
behavior differences between laptops and mobile devices like phones and 
tablets.  You might notice on a laptop Zoom session, maybe not with an iPhone 
VoWi-Fi session.  Our focus was on VoWi-Fi, thinking it was the more 
challenging thing to tackle.   Remote learning is challenging those assumptions.

Subject: Re: [WIRELESS-LAN] Client roaming

On thing to keep in mind is that iOS devices start behavior poorly when they 
have no good option above -65.  That’s the threshold they prefer 5GHz and when 
you combine that with “hallway design” and “band select” you are asking for a 
bad time.

Scenario:
Client doesn’t see 5GHz above -65.  2.4Ghz looks better, client tries to 
associate and bandselect tries to send them back.  Client doesn’t think 5GHz 
meets its requirements, tries to associate on 2.4Ghz.  Round and round they go.

If you need band select for devices like iOS that prefer 5GHz, you likely don’t 
have enough 5GHz coverage, and trying to force them to 5GHz only results in 
issues.

A better approach is to have at least 6db of transmit power more on 5GHz than 
2.4.  This makes 5GHz generally look more attractive so clients naturally pick 
it, band select not needed.  You can easily do this with TPC min/max settings.

Also keep in mind when looking at your survey reports.  -65 is as measured by 
the device, not your fancy sidekick or aircheck.  Figure you need an extra 
7-10db delta to overcome the limitations of some mobiles devices.  That puts 
you -58 to -55 as measured.

Re: [EXTERNAL] Re: [WIRELESS-LAN] Client roaming

[Mallon, Jason]

Agreed, an iOS device at -65 starts roaming and acts wonky from time to time.  
The issue we run into a lot is, which iOS device do you design for?  Do you 
design with the iphone 11 or 10, or do you design for the frst SE, 6, or 7 that 
are four or five years old now?  With iOS devices able to get code updates for 
4 years do you still consider them a relevant device on the network, when you 
might see only a handful of them.  I went back through my tickets earlier 
today, and did notice that most complaints are from macOS and iOS devices.  As 
the wireless cards get better at what point  do you start eliminating the older 
equipment off of your network when you are BYOD?

We are seeing a lot of this on the 1815w’s.  We are getting complaints in dorms 
that have 9115s and 2802s as well.  I am going to fix the building with the 
2802s tomorrow to see if that helps them any.  Same thing we get 1 complaint, 
but everybody on the floor is having the issue.  I am not hearing the 
complaints in academic areas, either and I have a lot of ceiling mount APs in 
those areas.

Clients do roam aggressively, but I am confused as to why they are roaming at a 
-55 5 radio to a -70 2.4 radio.  The client cannot be thinking that connection 
is better.

A lot of devices roam aggressively once RSSI falls below some threshold level.  
It was -70dBm for a few years.  It started on Apple products and was soon 
copied by Samsung, Microsoft, and many others.  I’ve long treated roaming 
issues where the 5GHz signal is around or weaker than -70 as coverage problems, 
and when we improved the coverage the roaming problem went away.  This year 
we’re seeing the problem where the 5GHz signal is clearly better than -70.  Not 
sure if the threshold changed on the client devices or if something else is at 
work here, but something seems different this year.

We're getting hit with this too, and have a case open with Cisco on it. Next 
step is to set up some live debugging...
We have two 8510's paired for failover, upwards of 3,000 client wi-fi devices 
connected, and we've had maybe 20-30 reports that might be related to this.
We may have clients who are feeling it and putting up with it, we're hearing a 
few say "everyone on my floor" etc.
I agree there are certainly some new practices going on, with students holed up 
in their rooms on Zoom meetings all day!
Specifically on the reports we're getting, we're seeing multiple platforms 
(everything from MacOS, iOS, Windows, Androids) roaming around to the nearest 
2-5 ap's on a regular basis.
It's usually from a student who doesn't have an ap in their room - we have 
Cisco 1810W's approx every other room.
Not hearing any reports of this in NON-residential areas, which are all 
2700-series mostly out in hallways etc
Less roaming options, makes sense... hmm, maybe shut off half our 1810W's in 
the dorms? :D

Subject: [EXTERNAL] Re: [WIRELESS-LAN] Client roaming
We’re an Aruba shop and have noticed similar behavior.  We’re having more 
incidents of intermittent connectivity issues this year than in previous years, 
and most of those clients are making questionable roaming decisions.  It’s been 
really prevalent with iOS and MacOS.  Much less on Windows and Android.  
There’s always been problems with picking a good radio when those devices first 
connect, but, historically, once they were steered to a good 5GHz radio they 
stayed there.  They’re not staying there this year.  We haven’t figured out why.

Wondering if anybody else is seeing this.  We currently have devices doing a 
lot of roaming between 5 and 2.4 radios, especially in the dorms.  I would not 
think anything of it normally, but they are moving from a -52 to -58 on the 5 
radio to a -75 or worse on the 2.4 radio.  This doesn’t seem to matter what 
SSID they are connected to.  Band select is enabled on all SSIDs.  We are

We are in the process of upgrading our wireless from a Cisco 8510 to a Cisco 
9800-80. I wanted to query those on this list who have already gone through 
this process about any lessons learned that would have been nice to know before 
transitioning your existing AP inventory that is compliant with the new 
hardware. I am building the configuration for the 9800 from scratch and it has 
been a challenge learning the new concepts for configuring this type of 
controller, so I was hoping to see what others have learned from the 
experience. Any thoughts would be appreciated.

[Mallon, Jason]

Mathieu,
Our Android is a little on the bare side.  Most of our mobile devices are iOS 
based, and they were still seeing the issue.  It was honestly pick and choose 
what would connect and what wouldn’t.  Sometimes trying for 9 or 10 times the 
device would suddenly connect.  This didn’t matter if it was eduroam or PSK.  
We have had good luck with adaptive Fast Transition across all devices.

I’m with you on 8.10MR4.  Not ready to start testing another controller code.

Regarding 8.10.130.0 Our IT helpdesk has had their work on upgrading NIC’s. 
Most of our issue’s are solvable with updating the NIC or manually making a 
profile in W10. The eduroam cattool has helped a lot as well.

I  saw that there is a beta for 8.10MR4 but I’m not to keen to experiment with 
this.

Upgrading to escalation build 8.5.161.6 helped a lot here. Not sure if that

*Message sent from a system outside of UConn.*

Hello,

Our residential students returned to campus this past weekend. Since then, we 
have had numerous reports of student devices unable to access the internet in 
their rooms after connecting to our SSIDs. The #1 reported device type is Roku. 
Rebooting the access point in an affected area usually allows non-Roku devices 
to gain internet access for a while.

Reading up on Roku inference via Google searches seems to indicate that they 
have several problematic features such as “Device Connect” and “Interference 
Mitigation” that cannot always be disabled depending on the type of Roku device 
and its software version.

Our residence halls all have Cisco 3802 access points. We were stuck on 
8.3.150.0 until recently but we got rid of the older access points that were 
holding us back over the summer. We upgraded to 8.5.161.0 around the beginning 
of last month and there were no reported issues from the few people living the 
residence halls. This is the only change we have made to the controllers since 
Spring semester.

We opened a case with TAC on Monday about this issue but they have not been 
very responsive. We had the case requeued yesterday and the new engineer is 
looking over some logs.

I know that devices like Rokus that broadcast their own SSID (hidden or 
otherwise) have always been a nuisance in the residential WiFi realm but we 
have never been hit this hard. Is CleanAir bugged in this version? Has anyone 
else experience this? What did you do to get it resolved?

Re: [EXTERNAL] Re: [WIRELESS-LAN] WLC 8.10.121 Deferred

[Mallon, Jason]

We have WPA2 and WPA3 checked at this time.  The only issue we have seen have 
been with Windows 10 devices.  We have a handful of Android 10 devices that as 
far as I know are mainly Pixel and Samsung that have not had issues.  No Mac 
issues that I have heard about.

A. No. WPA2 + WPA3, but only WPA2 is checked. I will experiment with this when 
I get back to the office. The big problem is it's impacting Windows 10 PCs. We 
have not seen the issue with iPhones or Android devices, but there may not be 
enough of them on campus right now to say for sure (we don't have a summer 
semester). We do have Mac's having a similar issue, but forgetting the SSID and 
re-selecting fixes any auth issues we see there.

Q. FYI:   I noticed that  "over-the-ds" setting changed when we upgraded from 
8.5 to 8.10.121.0.  There may be other settings that changed as well.

A. One of the engineers mentioned another setting was different (sorry, can't 
remember which it was), but then he called me right back and said that wasn't 
the issue. I believe there was something he found in the logs based on the 
conversation, so hopefully we'll have more info soon. It might've been beacon 
related, but I could have that planted in my head from an earlier post.

Q. There was a memory leak in the AP. Clients were not moving from 
authentication to the AP through the association phase on the controller.(these 
terms seem backwards to me backwards -- authentication is finding the AP, 
association is the 802.1x/radius part). The AP was not forwarding the 
association PDU to the controller (so the radius servers never got to see 
request let alone send a rejection). Rebooting the AP at the time /might/ fix 
the problem, but if a large number of clients immediately connected to the 
newly rebooted AP it ran out memory and became semi-operational again. I'd 
check the AP rather than the controller logs to see what it's reporting.

A. There's not an AP model on the campus that we've found the behavior any 
different. In our office where we test, it's a 2802 ... but the issue exists 
with the 3800's and even the new 9100's as well.

Q. Have you tested your Android devices with FT disabled? (instead of FT 
Adaptive). I would be curious to hear what results you get.

A. We haven't seen any issues with Android devices (yet), but we don't have 
enough on the campus to say for sure. We did go Adaptive at the suggestion of 
Cisco and a Presidio engineer because of some issues with iPads. So, I wouldn't 
be keen to change that.

We were running 8.10.121 on our 5520 and began having authentication issues. It 
is weird because radius isn't even seeing the attempts (or weren't logging 
rejections). The behavior persists even using local authentication. Eventually 
we can get the clients to connect, but it takes a number of attempts. It's very 
frustrating.

Cisco had us upgrade to 8.10.122, but the problem still persists. We would roll 
back, but we have 9130's on the campus now and we need 8.10.122 to manage them.

Such a headache right now.

Chuck,
We can get the Xbox’s connected on to our guest network with ease, but moving 
them back we are still seeing the issue.  We were able to get him to download 
the new code from the guest network, and that didn’t fix the issue either.

I’m not saying this is what you have, but around October we started getting 
XboxOne issues.  If you run the network test on the console you get an error 
forming the Teredo tunnel.  Neither a soft nor hard reset of the console fixes 
it, but switching networks seems to.  In our case we have the user connect to 
guest, then move back to the IoT SSID, and that seems to fix it.

FWIW, this seems to correlate with an update of Call of Duty Modern Warfare and 
there’s chat in the forums about that update having the same effect on home 
networks.

I can’t provide much more precise detail because I didn’t work on it myself.

Chintan,
All of our older dorms are wired currently wired, and are both pod-style and 
apartment.  These all have wires in them.  The newer dorms all of which have 
been pod-style are wireless only.  New construction we are using ceiling mount 
APs like the 1815i or 2802.  In the older dorms that we have to upgrade, we 
will be using the hospitality units (1815w).  We have them deployed in a couple 
dorms now and the coverage has been great.  We are also removing the hard lines 
in the older dorms and going to wireless only.

What code / controllers will you be using?  We looked at this as an option but 
with the 8540 and 8.9? code we found that most of the 802.11ax functions wont 
work.  If you are considering this you may want to reach out to your SE for 
specifics of what works and what doesnt.

I've never liked the idea of mixing models of aps in areas but have lucked out 
and not had to do it so not sure of all the cons.  One thing I would be aware 
of is devices that hold on to newer protocol versus better signal/performance.

Re: [WIRELESS-LAN] Deploying Cisco 9120's with existing APs

I am testing 8.10 right now using a 2800, 1815w, and a bunch of 2700s.  I 
haven’t seen any issues with any of those APs as of yet.  So far everything has 
been running smooth with zero complaints.  The only issue is a cosmetic bug on 
the 1815w (chatter: simple_action packet too short (expected 0x300, payload 
18)) that has been confirmed with TAC.  We have our first batch of 9115s, 9120s 
and 9130s on the way, so the upgrade is coming sooner rather than later for us 
as well.

Outdoor wireless

[Mallon, Jason]

Hey everyone,

Recently, discussion has started to evaluate wireless coverage all over our 
quad area.  We currently have 4, 2700s with patch antennas (AIR-ANT2566P4W-R) 
on the side of buildings with those hitting their limit of 400 clients at given 
times during the day (Probably just a lot of background noise).  I am not sure 
on the capacity they will want covered at this current time.  We do know there 
will be some on light poles, and we were thinking bollards also, other 
suggestions are more than welcome.  I also don’t know what other universities 
are doing as far as open areas for coverage, high density or not?  What to 
expect as far a congregation on the quad?  Will this bring more people to 
sitting on the quad and doing course work?  Will students be out there just 
streaming?  Any ideas or information from those who have done this would be 
greatly appreciated!

Re: [WIRELESS-LAN] Theater wifi - to have or not to have

[Mallon, Jason]

As of right now we are only doing wireless backstage and in the ticketing 
booths.  There is some bleed over into the audience section, but we are not 
trying to cover an entire theater.  Haven’t been asked to do this as of yet.  
All of our theaters have been in place for years and getting this done now 
would be a nightmare.  If a new theater was coming up I would probably do the 
design work and get the pipes to the correct places so that we would have the 
option to do something in the future.

Thanks,

Subject: [WIRELESS-LAN] Theater wifi - to have or not to have

Hello all,

I’m wondering if anyone here has dealt with a decision on wireless in the 
theaters, concert halls, or recital halls on their campus. We have a new arts 
complex coming on line in the next two years and there’s no clear direction 
from faculty on whether wireless for the audience is desirable. The previous 
main theater, and other currently used theaters on campus, did/do not have full 
connectivity for the audience (just a few aps tacked on the walls that were 
useless when the room was full). Facilities planning is favorable toward 
building it in, so I’d prefer that too, especially since it would be much 
harder or impossible to install if the faculty changes their mind in a few 
years once the building is complete. However, I’m not sure whether there is 
really an expectation from the audience that they should have wifi when they 
attend a show or concert.

Has anyone dealt with this on their campus? What influenced your choice?

Second GT’s comments, but would also suggest looking at iBwave. Unfortunately,

The software most predominant in the industry is from Ekahau. Most of us that

with the software.

If you decide to purchase it feel free to reach out to me. A friend of mine is

Re: [WIRELESS-LAN] Cisco 8540 WLC random reboots

Thanks for the input on that.  We have another pair of 8540s I could try this 
with and see if it works.  The current setup has been working for months with 
no issues then all of a sudden last week this all happened.

We had this issue very recently when upgrading our 8540s from 8.2.166.0 to 
8.5.131.0 (MR3):

A few days after the upgrade, the Standby 8540s started going through reboot 
loop, because it had an NaServCaCert_p12.pem certificate missing from the 
Active 8540. When the Standby can’t find the certificate on the Active 8540, it 
starts rebooting, until the Standby mercifully goes into Maintenance mode. 
During one of the reboots the certificate is restored on the Standby (I am 
told), but the Active 8540 still needs the NaServCaCert_p12.pem  certificate 
manually uploaded, in order for the HA SSO pair to be restored.

If one took the path of 8.2.x … upgrade to 8.3 (NaServCaCert_p12.pem created 
here?) … THEN upgraded to 8.5.X, you do not encounter the missing 
NaServCaCert_p12.pem certificate and rebooting standby WLC.

My mistake, I misunderstood.  Yeah, then, from others said, it would seem that 
our best bet is to get that MR3 version of 8.5.131.0.  That is what our local 
Cisco SE told us to do when we met up with them in late June.

FWIW, we run all of our 1815w APs on code version 8.5.120.0  in FlexConnect 
mode (although they worked when we tested them in Local mode as well).  I 
thought you might like to know that you potentially don't need to run them on 
8.4 code any longer.

Re: Cisco 8540 WLC random reboots

[Mallon, Jason]

I am curious what HA bug are you having an issue with an 8.5.131?

Hi, yes, it is, but the 8.5.131 code that is out now has a major HA bug that is 
very hard to recover from.

Cisco wireless engineers promised us code by the end of July that will address 
that issue.

Lots of bugs in 8.5.120, including some giant HA bugs.

The version of 8.5.131 coming later this month is where you'll want to be. 
Specifically, one of the fixes in the version of 8.5 coming later this month 
deals with HA issues.

a continuous boot loop.  We restarted one of the controllers to its emergency 
code (8.2.166) and it rebooted correctly without any issues, disabled SSO mode, 
rebooted back into 8.5.120 with no issues.  We enabled SSO again and 
immediately went back to having boot loop issues.  Is anybody else seeing this 
issue?
