SP2 ate my Hamster.

Yesterday I installed SP2 onto my computer. I did a sweep with adaware but the first attempt froze halfway so I rebooted, uninstalled it then disabled all major programmes running in the background and installed it again, this time it seemed to work. After that everything seemed fine, no apparent problems.
This morning I get up and I can't connect to the internet. So I check the cable on the wireless router and check the internet on the other two computers and everything there is fine. So I reinstall the drivers for my wireless dongle, still nothing.
The computer can still see the wireless network it just seems incapable of connecting to it properly. When you reboot it starts up connected but it will not connect to the internet, when you disconnect and reconnect it says something about the connection not being complete.
Now the only thing that has changed is I've installed SP2 and I don't quite get it as the wireless and the internet worked fine all day yesterday after the installation. But today it's decided against it.
The Messenger Live trouble shooter says somethings up with the default gateway.
Any ideas?
