Loss of internet connection after upgrade from 8.04 to 8.10

Like the title says, I lost my internet connection after upgrading my Ubuntu system from 8.04 to 8.10.

I used the downloaded automated method. It appeared to work fine on its initial reboot into 8.10. But I noticed the internet icon indicated loss of connection. Even so, I was still able to browse the net through Firefox. But then when I rebooted the next day the opposite was true: the connection icon indicated connection, but Firefox would not actually connect, nor would update manager. It has been like this since.

This is a dual boot machine, and the Windows XP Pro side still connects to the internet as usual, no problems.

So how can I make my new 8.10 system connect to the internet?

Here's more info:

I'm having a very similar problem.

Upgraded from 8.04 to 8.10 in the same automatic way. When i restarted there was no network connection sign, and i couldnt connect to the internet with firefox/update manager etc

i also have a belkin wireless router though. Were you running your drivers through ndiswrapper? I feel thats where the problem is. Although my drivers show up in ndiswrapper, as does the hardware. They just dont seem to be coming together to actually give me internet.

Any help would be greatly appreciated. Cheers.
