Curtis:
I have seen issues w/ R700s, specifically on the 5Ghz radio. (running a ZD3050 w/ 9.10.0.0 build 218)
Most of the R700s work most of the time but sometimes one of them will flake out.
Clients get intermittant connectivity and sometimes no connectivity but usually stay associated.
Because the problem is seen on the 5Ghz side, mac users (and computers with wifi configured to prefer 5Ghz connections) often report the problem when other PC users do not.
Rebooting the the AP resolves the problem.
My problem is finding out which APs need to be rebooted and when.
Does an AP reboot give you some relief?
