Brand new Aspire 751h, I wiped XP and installed 9.04. (I tried 9.10, but wireless didn't work at all.)

Anyway, WIFI worked great, WPA-2 at work, so I updated everything after the install. Since then, I can'tget the wireless to work. The network manager says there are networks, it asks for passphrases, it says it's connected, the router says I'm connected with an IP address, but Firefox and update cannot connect.

Here's some stuff to look ate:

I'm not completely daft, I've installed Ubuntu on two notebooks and two desktops over the last couple of years.

Anyone have any advise to offer?

More info: I can pull up the router config page by typing in the IP, so it seems the problem is with DNS, but only on wireless, and only on this new machine.

* I have a wireless connection to this new notebook. The Router confirms this, but I can't connect to anything but my router.
* I can ping Google.
* Everything works when I use the ethernet connection.
* Everything works on another wireless notebook sitting beside the new one.

I'm at a loss. HELP!
