I just set up a new computer with win 7 - 64. The cable broadband download speed is less than 1 meg/sec. My wife and daughters computers, which are wireless, see now slowdown. My computer is connected to the router thru the ethernet connection.
The previous computer using win xp - 32, plugged into the same router had no unusual speed problems. I did turn off the windows 7 firewall. Did no good.
Could there be some incompatibility between the router and win 7 - 64?? Are there some settings that need changing?
