Our system was working pretty well and then we upgraded 2 AP’s to 2.4.0. Now we are having all sorts of little issues.
We were working in a 20 MHz band and the PER on a few clients (less than a block away with clear LOS) was high. We increased the power on the A5 and changed to 40 MHz. The PER is now much better, but we have had various things that are strange.
On one AP, we had to power cycle the client 3 or 4 times in order to get a connection and IP address from the router. I think 2.4.0 may have introduced an issue that seemed to have been fixed in 2.3.0. Nothing has physically changed in our network and we may be having DHCP issues again. We use Mikrotik routers to hand out DHCP at each tower.
I’d be curious if anyone else is seeing anything strange with the new 2.4.0 firmware. It’s not consistent, so could be a client router or something else. I know there do not seem to be issues with a G2 behind the C5.
