Hi Mathieu.
Thanks for this information !!!!!! We currently use 8.5.161.6 and there are known (DHCP) issues with AP2800 ! I will try to disable MU-MIMO and wait (again) for a fix…. Ps : #CSCvv78719 is a severity 2 bug !

Since the client was already connected they couldn’t roam to another AP.

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.

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. <https://eur04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.cisco.com%2Fweb%2Fsoftware%2F280926587%2F153915%2FRelease_Notes_8_10_139_43.pdf&data=04%7C01%7Cg.scharloo%40UVA.NL%7C39f321b7466f497a759208d88d25f8fc%7Ca0f1cacd618c4403b94576fb3d6874e5%7C1%7C1%7C637414541526424049%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=Xlk1PlSeWQIksmwVQEg6CqDPtC7ft0t%2F4Br5ssZT4DI%3D&reserved=0> https://www.cisco.com/web/software/280926587/153915/Release_Notes_8_10_139_43.pdf Jeff From: The EDUCAUSE Wireless Issues Community Group Listserv < <mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> On Behalf Of Mathieu Sturm Sent: Wednesday, September 23, 2020 3:07 AM To: <mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU 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.
