I have four 7xxx-class Macs sitting here right now with bad RJ45 ports. And I have two others with totaly blown NICs.
2. Is there anything special I should look for
Check for bent pins, dirt, loose board connections, etc. Worth a try a least...
Thanks to all who responded.
In my case, it was never a question of the ethernet cables. I narrowed it down to the 7600's RJ-45 port by trying cables with other Macs and with other ports on the router. Everything worked except for the 7600 port.
I had never heard nor experienced a port going bad like that. In fact, in all my years of Mac computing and various machines, the only Mac components I have ever had "gone bad" by themselves were a PB 520c CPU, a hard drive and various PRAM batteries. I guess I expect my Macs to just work.
My current work around is to use the AAUI ethernet port with an adapter I already had. In the longer run I expected to migrate to a Beige G3 minitower anyway.
If it was solved by using the AAUI adapter, then the problem absolutely is with the RJ45 connector, since the AAUI and RJ45 connector connect to the same Ethernet circuitry. Possibly a broken connection on the mobo, a dirty or bent pin.
