I recently set up a home network. Using Linksys WRT54G Router. I have two computers currently hooked up to it. A wired desktop and a wireless laptop. Both of these are running windows XP. I have since bought a new laptop with windows vista and a built in wireless card. The new laptop will not locate my signal being broadcast from the router. Any suggestions on why this could be? Do I need to update firmware or is this a XP Vista compatibility issue? Please help thanks.
