HowTo fix: Airport has a self-assigned IP address and may not be able to connect to the internet.
Sunday, May 9th, 2010My girlfriend could not connect to our network, and Airport told her: Airport has a self-assigned IP address and may not be able to connect to the internet.
The problem was that her mac would self-assign a IP address, 169.x.x.x and Subnet Mask: 255.255.0.0. It seemed to be connected to our Time Capsule, though it did not get a IP address by the DHCP server. I tried renewing the DHCP but that did not work. I also tried accessing a ip address, as it could be an DNS error, this was not the case either.
Problem solving
I fixed the problem by manually setting up the network settings, to make sure they matched my own in, DNS Server, Router, Subnet Mask, and IP address +1. That worked but this could only be a temporarily solution as she uses her mac multiple places.
So I adventured out into the great indexed space of google to find a solution to the problem. As it turned out quite a few people was addressing the problem, and it seems to be a problem that Apple have had this problem for quite a while. In my search I found the problem has occured in an update to Apple OS X Leopard somewhere between update version 10.5.2 and 10.5.6. While the mac in question is at OS X 10.5.8 the problem still seems unsolved by Apple.
