What looks to be very similar to the 350 conversation...! I have one that the user is saying they cant get internet access through it occasionaly, and then it just comes back. The logs show the ethernet flapping, but the switch doesnt appear to have an issue. The AP wasnt rebooted for several months, so it isnt the AP going up and down. this is from the logs, does anything look out of the ordinary?

This could be a hardware problem.

what is the make and model of the ethernet switch? What is the speed and duplex setting on the AP and the ethernet switch?
