sorry your doomed, you got a linksys router *LOL* sad sad moment.
all kidding aside...do you know how to do port forwarding? if so then forward these ports to your laptop
TCP: 27030-27039
UDP: 1200,27000-27015
that will help - don't forget to SAVE (in router settings) then Power cycle the router. May also want to setup your computer as a set domain, not auto configure. Linksys...default would be 192.168.1.1 (being the IP of the router). Set your IP address to 192.168.1.100 and your gateway and dns server to 192.168.1.1
that will help.
