I simply cannott get rid of my 169.254 ip address, and I have tried everything!
My ISP requires DHCP, so I set up the mac to use DHCP and configured it per my ISP's instructions for proper built-in-ethernet use. Airport, bluetooth, etc, have been turned off and are not even selected in the network port config, proxies are off, everything else is correct, but I get nothing.
I have powercycled the mac about 20 times, in every possible configuration (eg - swap cable ends, manual release/renew, et-al, and...nothing.
I tried the assistant, no fix, it simply wont detect my ethernet connection.
The sad part is, after all this I just slap the ethernet cable into my PC, and walla! Instant internet.
I am 100% positive this is not an ISP, modem, cat-5 or cable line problem. I don't have a router.
Please, someone help.
