we have a laptop runnig xp pro with a internal prism wireless pci card. it works fine at one location with the wireless, but does not even see the the access point at this other one. it is about 3 feet away, and there are 2 other wireless clients on the network. we have already reinstalled the card, and tried to change the router to be in view of the prism's scanning range, for some reason it was only scanning channels one and two. any help greatly appreciated.
