Lost LAN connection

I have four computers here. Two PC's (wife's laptop and my internet machine) have recently been infected with all kinds of spyware. Now, neither of them will connect to the internet or even pull a valid IP address from my Linksys WRT54G wireless router. In the process of removing the spyware, I killed something on my computer that I really shouldn't have. Now, I have a Packet Scheduler Miniport that won't start, cause it isn't in the registry anymore, but I can't uninstall it either becuase allegedly Windows needs it to start up. On her laptop, I have been removing spyware left and right but haven't changed the registry at all.

My IP's on both machines are 169.254.XXX.XXX. When I try to repair the connection I get "The following steps of the repair operation failed: Renewing the IP address. Please contact your network admin or ISP."

On her laptop, it sees the wireless connection just fine but it still won't get a good IP.

IPConfig /release won't do anything. IPConfig /renew tells me "An error occured while renewing interface blah: An operation was attempted on something that is not a socket."

On my gaming machine, I did /release, then /renew and it worked just like it is supposed to, so I know the router is working. Server also connects to internet just fine.

Does anyone have any ideas?? I don't mind re-installing XP on my machine, and it is about that time, but I don't want to dig out the restore disk for her laptop. Thanks!!
