I've just upgraded my computer with a new motherboard and CPU, and now I can't connect my computer to an existing home network, or the internet through the network.
I use WinXP Home connect to a router which is connected to a computer which acts as a gateway to an ISDN internet connection. I don't think my problem is with that computer or the ISDN connection as there are already two others connected to it and they have no problems.
I can see my network card in the System properties window and it's working alright. In TCP/IP settings I have tried it set to "detect settings automatically", and that makes the network status say "acquiring network address" indefinitely. I have tried it with the IPs that I had before I upgraded, which were 192.168.0.1 with a subnet mask of 255.255.255.0 - and then it says that another computer on the network has the same IP.
I've never really done any networking before and my roommate who set it up has moved out Can anyone help me?
