There does seem to be something wrong with it - the signal quality is 
claims to get from the access point is about 50% - which is weak 
considering the access point is about 15 feet away. Also it constantly 
backs off the rate from 54M down to 1M - my guess is either the wireless 
card or the router are decrepit - does that sound reasonable?
