2 ethernet adapters?

Hi. Last week my (cable) was down and my isp came to fix it. Since then I have been having trouble connecting through specific ports. I have 2 computers networked (this one, 98se, the other, XP) through a Linksys WRT54G. The XP computer has no trouble with the ports.

 

The only thing i have noticed any difference in (forwarded ports are the same, ips are the same) is when I run ipconfig on this computer it lists 2 adapters:

 

0 Ethernet adapter:

IP address: 0.0.0.0

Subnet Mask: 0.0.0.0

Gateway: (blank)

 

Followed by:

 

1 Ethernet adapter (etc, etc) which lists the correct numbers. I do not recall having 2 adapters listed before the cable went down (my XP comp lists only 1), and if this in fact my source of trouble, how does one change this. I thought of uninstalling the ethernet card, but was unsure if it would get rid of both.

 

Any help would be appreciated. Thanks.
