So I ran out a bought a new wireless card this afternoon, loaded up the installation disk, plugged in the card and voila! a very quick, great connection...for 15 minutes. And then, the same old problems: pages not loading, the connection timing out, sluggishness, etc., etc.
Called Norm at work and we both wondered if the slot the card slides into is shot or one or more pins are bent or broken. Norm had me talk to one of his co-workers, who suggested that something may be getting too hot and shutting down.
SO thirty-five bucks later, nothing solved, but one more possible problem crossed off the list.
Computers...gotta love 'em.
