Have router but computer tries to dial-up
Hay, my computer is a dell PC with a pentium 3 processor and xp. I'm a student andlive in a house where the router is upstairs and a I need connect my PC using my wireless card to the router upstairs. I've been able to get my card to find our houses server and establish a connection with the router upstairs. However, when I click on the explorer button it comes up saying 'dial up' and stuff and tries to dial instead of connecting through the router. I know nothing about computers. I looked on another website and they said that my problem is that I don't have an ip address (I know I don't have one of these). How do I get one. Help!!
Thanks for taking the time to respond to this.
