If you still havent figured it out, disconnect everything from your modem and connect 1 PC to it to see if its a bandwith brownout in your area. I didnt catch if its a cable modem or DSL, DSL should not brown out( weak signal) Cable can.
Hey Rusty, i'm on DSL. Another thing is that obviously, me paying the bill, i have the best equipment on my rig, so i connect to my "N" type hub via my ring main, as due to the construction and lay out of my home, wireless didn't work for me very well. The other pc's and laptop, ps3, 360, psp, wii etc all connect via wireless. I've run tests on the other machines and they don't appear to have any issues, just that they always seem to have a higher ping rate than me, but i put that down to them connecting wireless and on "B&G".
cheers
