Dear All,
One of my wi-fi site having 2nos cisco 2950 switchs. in that network some D-link unmanageble swithes also there
and access points also connected to cisco switchs and D-link switchs.
after one or two days i am not able to connect the wi-fi, then i need to restart the access point then only wi-fi is working fine.
I upgraded the latest ios also.
I connected some access points to the cisco switch ports, those ports are showing crc error messages like below.
145 input errors, 144 CRC, 1 frame, 0 overrun, 0 ignored
and log file also show some errors like below.

is there any logs on the WAP side?
try to connect the device directly using a small (1 meter or so ) cable.
