Hi there,
In this problamatic school there are 3 D-Link 2100+AP's. They have different SSID's and are transmitting on channel 1,3,6 (ah should be 1,6,11 will change that on Monday), they are solely used as Accees points but every so often they stop transmitting. Its as if they crash and the only way to get them operational is to power them off and back on again. You can't even browse to them once they crash they are completely dead but lights are on and blinking.
This can occur after 10 minutes or 6 hours, its completely random as far as I can tell and it happens to all AP's at different times.
Assuming it isn't the small gap between channels I'm stumped, I don't think its interference from outside as just down the road I set up a wireless network a month ago with no problems (yet).
Any help please would be a god send.
