So, the built ethernet will not communicate with the N+ Belkin router I just bought. I don't think the ethernet cable is a crossover (plus it worked when plugged directly into the cable modem, it also worked when setting up the ibook) and when I plug both ends into two of the four slots of the router the "wired" light comes on (according to folks at Belkin this proves my cable is good). The Belkin folks are blaming my ethernet port and believe there is something I could do but can't help reconfigure the ethernets IP address???????? Just to double check, I hooked up the belkin with my ibook G4 (much newer) and it worked fine through the router. The ibook has airport, do I need Airport in my old G4 desktop? Can't I just leave it connected to my router (if it worked) The whole point is to get two computers on line at the same time. Would anybody like to share some thoughts?
