I should add: I also am running a PS3 (60GB-Feb. 07 I think) which plays online pretty well, and an iPod Touch which works pretty well. Also a Mac on Ethernet-is fine
Also, the router/modem have always been in the basement, whilst the problem PC and PS3 are 2nd floor-maybe 20-40 ft (pretty rough estimate) (iPod usually used from same area too)-and the mac is 1st floor-maybe 10 or less feet away.
As far as ethernet for upstairs-not a job I want to deal with or pay for.
