check what channels routers around are using and change it i heard channel 7 is good always empty
48 Mbps is fine..

if your slow maybe it's your ISP

i still download on a torrent site at 1.4MB/s but i thought it would be faster with a 54 instead of 48 i dont get the difference lol. but what is netstumbler????
