Best thing you can do for clients is have a 5GHz only SSID. We moved over the summer to this with our main 802.1x network and it has fixed a ton of these roaming issues and complaints of performance. Basically take the decision making out of the hands of the client, give them only one band to choose from. Band Select / steering may work but can lead to a lot of users issues as roaming can break if the client doesnt take the hint to use 5GHz. Transitions with real time applications like voice can be negatively affected.
For those on our campus that have 2.4GHz only devices, we offer eduroam in both bands and have them use that then use AAA override to place them in the same network as our branded ssid giving them all the same access to resources. Our branded 802.1x, MWireless, has 95% of our user devices. -Jimmy -- James Helzerman Wireless Network Engineer University of Michigan - ITS On Fri, Oct 9, 2020 at 12:03 PM Enfield, Chuck <[email protected]> wrote: > FWIW, I’ve been reluctant to assume this is a new problem.
