    I am running a Macbook Pro 2.2ghz, 2 gb of memory on Mac OS X 10.5.8.

    When I plug in my ethernet cable it self assigns an IP address and the internet does not work.

    I have searched around for solutions but mainly get problems with airport and this seems to be a direct connection issue.

    Could it be a problem with the ISP?

    Any help is welcome thank you so much!

    Well, you haven't told us what's on the other end of your Ethernet cable! :) Usually, it's a router, which must (well nearly always must) have DHCP enabled. That's what gives out proper IP addresses, like 192.*.*.*

    "Self assigned" means your mac didn't get your address from your router through DHCP but rather choose one itself. Could be your router which isn't configured correctly. I've also had this problem on a "hackintosh" (pc running OSX) where it would be fine after rebooting with the cable plugged in.
