Share my wireless net connection through a wired Linksys router to another PC?

[Colonel Sanders]

My PC connects to the internet through a Netgear RangeMax access point. My roommate's computer, which is a few feet away from mine, gets poor signal and we are getting latency issues in WoW on her computer (while mine has none) and we both have the same wireless NICs (US Robotics). However, my signal is good and I have no issues in WoW.

Is there a way I can simultaneously connect to wireless and my Linksys wired router and connect her computer to the Linksys and share my internet connection through it somehow?

Thanks
