i know this is a very general question to which there may be a thousand answers, but i figure the previous experiences of those of you on this site may help. i am using a desktop with a wireless linksys usb network adaptor. i continually have this problem where internet pages will not load while i have reportedly excellent signal and connectivity. upon "repairing" my connection the internet begins working again. not a big problem, until it happens every minute and a half. does anyone have any pointers that they wouldnt mind sharing? thanks.
