RE: Client roaming

2020-10-09 Thread Jeffrey D. Sessler
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.

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.

I have not been able to pinpoint a device type as of yet.  It seems to be 
happening across all platforms including game systems.

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.
