Do the gigabit ports on the AE need to "activated"?
i use my Airport Extreme to connect both wirelessly and wired - wired, via ''cat6 cable (75')''bold text to my iMac.
I can select 1000baseT in Network set-up for the iMac, but if so, I can't connect to the AE - gigabit is not an option on the AE and I can only connect if I set the iMac back down to "100baseTX".
BTW - forgot to mention that I bought it used, but ran the serial number and according to the specs on the Apple support pages, it's a gigabit version.
Any suggestions? Thanks in advance!
