How do i connect the 2 computers without loosing internet connection?
It depends on the OS’s on each PC. If you have either XP or Vista on both, then just buy a ethernet cable and plug into each port on each PC. Then it’s just a matter of setting up the windows or software firewall to allow traffic/sharing between each PC. The easiest way is to physically remove your internet connection network cable, or just turn off the modem/router that your PC is connected to for internet access. Then just turn off all firewall and anti-virus software temporarily while you play, then turn everything back on when u r done. In this way it will be very easy to set up, and you will be 100% secure from the internet bad guys out there.
