Hello i have facing small issue while connecting two computers with one router. i have installed the router with the ADSL internet and i just wanted to connect with the other computer. The first computer has windows 7 ultimate and second one has windows XP service pack 2. when i tried to connect the XP computer with windows 7 then the router was showing error message saying: "the cable is unplugged". i have checked the router and everything was plugged. Can anyone suggest some tips to solve this issue.
