When I plugged in my cable modem from my roomate's computer into the new one, it doesn't recognize the new device plugged into the ethernet input (which it always has for USB). So I go to the add new hardware option, and it doesn't recognize any new devices; however, looking at my Device Manager, it DOES show "Sis 900-Based PCI Fast Ethernet Adapter", though I don't know if that signifies any existence of an Ethernet modem being connected to said card. Using XP on my new PC, 98 on my old one. I'm scared. +Someone just told me that it's trying to get an IP from the modem, went to command prompt and typed 'ipconfig/renew' . It sat there for a minute and came back with an error specifying "unable to contact your DHCP server. Request has timed out."
