I am having the problem with my wireless performance... I have DIR-655 and iMac and Macbook connected wirelessly. When I try to transfer a movie from my macbook which is only 2 meters away from my iMac and the router is just next to the Macbook. Everything is in one small room. Anyone has this issue with this? I check on the router transmitting rate. my imac and macbook transmit about 107mb/sec but it is very slow when you transfer something from one mac to another especially to my appletv !!!
