I have a XP computer hooked up to a network which had some internet issues for the longest time. The issue would be sometimes during restarts the computer would not detect the router and other times I would get a perfect connection. Then sometime later the restarts would not help and I would just stop getting a internet connection. I searched about the issue on google and found out that my computer had DHCP labeled off when I did ipconfig /all. One of the solutions people brought up was that a network card could be installed and I could get internet from there, but that card does not detect any cables plugged into it. I have the computers set up with a static ip, but with the old network connection I got the ip 169.254.x.x when I enabled find ip automatically.
