Re: [WIRELESS-LAN] Odd incident on our 8540 Controllers- wondering if anyone has seen similar?

I’d settle for being able to jump to a new code version without upgrading everything. It’s a bit easier with virtual controllers, just spin up a new one and move some APs to it. Of course, even when you do that users still take a week to start reporting problems … -- James Andrewartha Network &

Re: [WIRELESS-LAN] Playstation 4 (PS4) Not Connecting to Wireless

We have had a few reports of PS4 problems, but as far as I can tell they are mostly because PS4's only have a 2.4GHz radio. Often the AP near them has gone into air monitor mode from too much 2.4 in the air, and the antenna on the PS4 isn't that fantastic. Plus, many students shove it in a cab

Have you actually confirmed that both devices are getting the same IP address offered via DHCP, or is it just that one of the clients is using that address without DHCP? If the latter, I would strongly recommend you turn on the enable DHCP feature on your VAPs to prevent statically configured
