Ron, I think your router experience is pretty common. When I was renting a room from a friend my router was piggybacking off her PC and my Mac worked fine. Since moving into this apartment TWO seasoned computer consultants have tried unsuccessfully to get the same router to work with my Mac, with no PC in between. The manufacturer's tech service rep was no help whatsoever--couldn't even read the script very well. I solved the problem by purchasing a $6 Ethernet cable. Inelegant, yes, but it does the job. One day I'll buy a new router--a Mac router--and try again.
