10.4.4 Possible Broke Network Settings?

[dapoppa1]

After upgrading to the 10.4.4, I"ve tried three sperate means of connecting at this point. All three worked before the upgrade. Through my wireless router, my bluetooth phone, and my neighbor's wireless. My WLAN is working for other computers. When I connect to my router, the airport indication light in the network status menu goes yellow, claiming that I have a self assigned IP address and may not be able to connect to the internet. Upon examining my airport TCP/IP settings, the ip address is set to something absurd outside of my LAN. When I renew the DHCP lease, it just reassigns the bogus IP. If I manually configure my IP settings the indicator goes green, and I should be able to connect at this point, but no luck. I cannot even ping the router with the self assigned IP address. I've tried resetting the router/cable modem etc., and I cannot connect to three seperate means, so I'm pretty certain this has something to do with the upgrade. This is driving me crazy... Has this happened to anyone else or does anyone have any suggestions?
