My graphite Airport Base Station appears to continually reset in the evenings from about 6pm until 8pm. The lights appear green for short periods (1-2 minutes), during which I get normal access, but most of the time, the lights are orange or red.
Oddly, it seems OK during the day and in late evening. It is hooked up to a router which is hooked up to our cable set top box via ethernet. One answer could be 'busy internet' but I don't see how this could be the case. Resetting the ABS has no effect. Curious.
