[MLB-WIRELESS] Strange interference side effect

[Horace Pinker]

I have been runing my ap for a few years now but all of a sudden i am 
getting some strange interference ?. The resulting weird side efect is that 
the lan part of the network dies, i can associate to the ap i can ping the 
ap but i cant ping the machine connected to the ap until i force an ap 
reboot. This has now happened to 3 ap's dlink200ap+ minitar mnwapb and a 
asus wl500g(standard firmware)

I havent pinpointed it to be interference at this stage as i also have a 
suspicion about bittorrent causing things to go fudd, so anyone else seen 
similiar thing any workarounds ?
Cheers
