Have a 1200 on the latest firmware 10.5.0.0 build 190.
some clients are either:
1. loosing the pw for the wifi point
2. loosing the ip address on the client, but teh 1200 clearly shows the mac & ip address as authorized.
if I go into "client connectivity" then start a test, it is continually stopping at "4-way Handshake - Frame 4" then goes no further (zone director)
Every other client (apart from 2 or 3)runs past this & into the DHCP request.
But if I reboot the 1200, then it all clear up & issues a dhcp lease, but some time after that, the client trashes the DHCP again and ends up disconnected, even though the 1200 shows the mac & ip address
There is not a shortage of DHCP leases or ip addresses, besides the DHCP is still valid according to the AD server & 1200
I have never had this issue previously....
