Hello, I have a dual boot windows 7 and XP PC (both 32 bit). I formatted the hard drive 3 weeks ago and installed fresh copies of Windows 7 (RC1 or 7100) and XP. Everything was working fine until today, upon reboot, my windows seven stopped connecting to internet. I tried several methods in the control panel to connect without any success. So I went back to XP and the internet connects awesome. This confirms that there is no problem with the router or modem (I use a university T3 connection-sometimes go to 8 MB/sec!!!). I had a similar few days ago and I restarted the computer several times and it connected to the internet by itself. Zthis time it doesn't want to do it. I was wondering if anyone has a solution to this problem. I really liked the Windows 7 and want to use it instead of XP. I have a custom built core 2 duo, 4 GB RAM (3.5 GB detected), 128 MB graphics card and 3 400GB hard drives. Thanks for any help.
