My personal belief is that even today, technologies like band select just compete with the secret sauce on the client side, and are subject to problems. Every time I've experimented with it, I turn it back off (cisco and aruba), as your success is often short-lived until the next device OS or driver update.
Specific to 8.10, TAC and the BU have recommended the interim 8.10.139.43 until 8.10 MR4 is out. As such, you may want to take a look at the release notes to see if there are any defects registered that relate to the issue. https://community.cisco.com/t5/wireless-and-mobility/announcing-cisco-wireless-8-10mr4-first-interim-8-10-139-43/td-p/4155055 Jeff From: The EDUCAUSE Wireless Issues Community Group Listserv <WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> On Behalf Of Mallon, Jason Sent: Friday, October 09, 2020 7:30 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: [WIRELESS-LAN] Client roaming 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.
