Vista Wireless Mapped Drive Issue

I have a little bit of a strange issue happening. We recent started having wireless access at my company. we are running server 2003, and have a Linksys Wireless WRT110 router hooked up. Everything was running pretty smoothly until I hooked up a vista laptop. I cannot access mapped drives from the server through the wireless connection, if I hook it up wired it is not a problem, but as soon as i just go wireless I can not access the mapped drive… does anyone have any advice for this issue?
