I recently wrapped up a new build involving an nForce4-SLi motherboard (specs in signature). I've taken it on the network where I normally stay, without any hindrances. However, I recently took this new system for a long-term visit with a friend. It does not seem to be coping with her network well. I've updated the drivers and NAM, but it is unable to secure a workable IP address on her network. I've manually configured it to use an IP address on the 192.168.1.x network, which theoretically should work, but though it registers just dandy with DNS, it still will not allow me on the network. Another strange thing is, I've performed "ipconfig /all" on her computer (which works), and it shows that the gateway DHCP is 192.168.1.1, but the DHCP my system tries to use when I enable it is 255.255.255.0. Any ideas? Responses would be greatly appreciated.
