Internet Problem

[BileGhost]

Hi, I've got a MacBook 3,1 (White, late 08 model) which is happily connecting to the wireless network but refusing to use the internet. Other computers on the network use it fine.

What's more, when I restart to my bootcamp partition, the internet works fine. It's only in Mac OS that I have a problem.

I have Googled around but failed to find anything that may help, so I would be happy to get any advice.

Thanks

First question would be, is the Macbook obtaining an IP address on the network?

You can check by opening System Preferences > Network > Airport

Is it lit as green and providing an IP?

Yup, it has an IP address and has connected fine.

I'm afraid that didn't work either. I've also tried resetting the PRAM, and resetting the SMC (just to try everything ), and running all the things in MainMenu. I've also repaired permissions in SafeMode. Still no dice.

Anyone got other ideas?
