Hello everyone,

We’ve been having issues on 8.10.130.0 where a client could connect to a 
certain 2800/3800/9120 but didn’t have network access. Since the client was 
already connected they couldn’t roam to another AP.

We first thought it to be this bug: 
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvv78366
Cisco thinks this is only cosmetic… so they now think we are facing this bug: 
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvv78719%20/?rfs=iqvred

Their (temporary) solution is to

Step 1
Choose WLANs and click the WLAN ID.
Step 2
In the Advanced tab, check or uncheck the 11ac MU-MIMO check box.
Step 3
In the 802.11ax BSS Configuration section, check or uncheck the Down Link 
MU-MIMO and Up Link MU-MIMO  disable MU-MIMO on 802.11ax APs.

I’m not to keen on doing this. It makes our 2800/3800/9120’s pretty worthless.

We also saw these bugs:

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvk68674/?rfs=iqvred
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvh04804/?rfs=iqvred

We are waiting for MR4 were hopefully these bugs will be gone (We can only hope 
😊)

We have upgrade 2/3 WLC pairs from 8.5.151 to 8.10.103.0 – seems to be going ok 
with the exception of DNAC-C reporting slower / more DHCP failures – while we 
have received no support calls – just wondering if anyone else has seen this?

Mathieu, thanks for the tip on the bug, now watching that too.

thanks

Little update, I came across this bug id: 
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvu65125/?rfs=iqvred<https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbst.cloudapps.cisco.com%2Fbugsearch%2Fbug%2FCSCvu65125%2F%3Frfs%3Diqvred&data=02%7C01%7Cmathieu.sturm%40HOGENT.BE%7C8f16fa3f458248ddd86808d86596c4fd%7C5cf7310e091a4bc5acd726c721d4cccd%7C1%7C1%7C637371045528043511&sdata=oRxCC%2BNXXmwGOXEMbFpukuN2uMj9Xjg1%2FUgBzxIbH%2FE%3D&reserved=0>
 (thanks Jeff for the hint about version 8.10.139.43)

So I decided to change the settings on the SSID from WPA2 + WPA3 back to 
WPA+WPA2 and this seems to have resolved our issues (we’re testing right now).

My wife is about to deliver our 2nd daughter so I will ask my colleagues to 
update if possible.

Hi,

Watching this thread closely.  We're currently on 8.5.151 but need to migrate 
to an 8.10 release for the 9130ax's.

If anyone has any TAC cases or bug IDs that may reference this issue, that 
would be super useful!

You probably want 8.10.139.43, which is fully BU supported and suggested for 
production. This is a link to the release notes, I’d check to see if any of 
these apply. Also, verify your timeouts aren’t set too low for the radius 
responses coming from eduroam.  I ran into this at Cal Poly in Pomona, where I 
could not interactively login to eduroam, but I could save my credentials and 
it worked just fine.  I suspected a timeout set too low (this was Aruba 
equipment however). Had an entire group there for a meeting that faced the same 
issues.

Subject: [WIRELESS-LAN] Cisco 8.10.130.0 eduroam issues

Hello,

We updated our Cisco 5520 controllers from 8.5.151.0 to 8.10.130.0. Since the 
update we have issues with eduroam. Before the update the students and other 
users could select the ssid eduroam and fill in the credentials and they were 
connected.
Now we have to update the NIC’s (mostly AX200) to the latest version and/or 
update to W10 version 2004. And even then we often have to configure the SSID 
manually and save credentials.

We see that the users get to the ISE and are permitted but the WLC doesn’t 
always see this permit. Or the ISE gives a certificate warning (I’ve checked 
our certificates, all are valid).

Is anyone experiencing the same thing?

We went tot 8.10.130.0 for our new 9120’s.
