I have Cox high speed internet access, two computers, and only one connection at a time. I have a new Siemens 1019 10/100 ethernet NIC card. I used to have a DFE card that worked good on each computer but the Siemens card isn't working or my connection isnt working.

-When I use this current computer (dad's computer), my internet connection works. When I use my computer, my internet connection won't work. I tried reinstalling the Cox software but it can't even retrieve my computer's IP address.

-Do you guys know what the problem is, what I can do to get my IP address working or what settings I need, other than calling COX support?

thanks
