Subject: [WIRELESS-LAN] Android 10 Weirdness - Cisco

Hi Gang,

I'm not sure how much of a problem this is on our network, and I haven't spoken 
with Cisco TAC yet. But I wanted to share what I have seen from a client, in 
case anyone else has seen the same issue.

We are running 8.8.125.0 on a HA pair of 5520s

We have an Android cell phone, running Android 10, that is reported to be 
disconnecting from the network. When I run a debug I see the following 
behaviour:


  *   Client associates to an 1815w in Student Residence
  *   Client performs an intra-roam on the AP from 2.4Ghz to 5GHz, or vice versa
  *   WLC sends an EAP-Identity-Request
  *   Client doesn't respond
  *   Client session is timed out and client is de-authed

This dance seems to repeat whenever an intra roam occurs and has only been 
noticed/reported when they are associated to an 1815w
New associations are fine.

Has anyone seen this before?
Could it be related to this being a sleepy client? Client goes to sleep, but 
the WLC fails to correctly define it and responds as if the client is just 
being unresponsive?
Could it be another AireOS bug?
Is this just a client side bug?

Thanks

Sean

RE: Intel 9560 Wifi NIC Experiences?

[Haynes, Jonathan]

https://www.intel.com/content/www/us/en/support/articles/54799/network-and-i-o/wireless-networking.html

We have just upgraded wireless in some of our residential areas and these have 
Aruba 802.11ax capable APs.  Several students have had issues until drivers are 
updated.  If these are centrally managed laptops however then you just have to 
make sure the drivers are updated after purchase.  Or if you have older non ax 
APs then there is no issue - we have not seen any problems outside of areas 
with the latest APs.

RE: Theater wifi - to have or not to have

[Glinsky, Eric]

I agree with the all-or-nothing stance. Better to have nothing than to have 
mediocrity, which frustrates users as mentioned. If nothing, at least have a 
design and wiring ready. Then buy APs and switches/blades when ready to commit.

We’re just beginning to talk about upgrading wireless in the main performing 
arts theater, which now has good coverage but not density, at the request of 
its manager. Yes, people should be paying attention to the performance, but 
that’s not the only thing the space is used for, plus I’ve personally 
experienced decent WiFi speed during a performance, but then everyone tries to 
use WiFi during intermission and it becomes useless.

Someone mentioned working with the sound engineers in the theater. Absolutely! 
Over the summer, we were asked to disable WiFi in the theater entirely because 
it was causing popping sounds over the headset system. Sure enough, the 
documentation of their system (HME Clear-Com DX – I have a PDF on this if 
anyone’s interested) states that it uses “Spectrum Friendly Mode” (ha!) 
utilizing either the high end or the low end of the 2.4-2.8GHz band, basically 
leaving us only either channel 1 or 11 to use for coexistence. We turned off 
2.4 GHz in the whole building and their issues reportedly went away, but the 
theater manager has since told us to turn it back on and we haven’t heard about 
it since.

I’ve been sitting on the sidelines in this discussion but wanted to mention 
something we are seeing for use in chapels, theaters and auditoriums. That is 
the use of personal cellular devices to assist hearing impaired guests in these 
venues. I believe the app is Listen Everywhere that has an appliance that ties 
into the sound system and the network to provide the service.

Are there others using these services?

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?

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

[Muraca, Peppino P.]

Hi , I would defiantly wire for access points and depending on what type of 
ceiling the architect goes with ( access to locations) I would add the waps. 
You can easily disabled them for events if requested.
Here at Stonehill we plan for coverage in every interior space, we have 
actually had our theatre arts people ask to expand wireless in the theatre.

Like others have said it is easy to add them now , and much more difficult and 
expensive later on.
