Why can't I connect wirelessly when I can connect via ethernet card?

My client has a Toshiba Satellite psm42u laptop.  I set it up for her about two weeks ago.  Everything worked.  She came back with it today and can't get on Internet via wireless but the wired works fine.  
The router is giving an ip address and a strong signal.  Certain functions work, like downloading microsoft updates, but email, firefox, ie, and updating avg antivirus doesn't.  They can't connect
the ip address to a valid website.  I disabled and enabled the adapter, ran Panda activescan and LSP fix and couldn't find anything, then did a restore back to about a week ago.  Still no luck.

it could be norton firewall, or any very strong firewall.

Check the following: Settings on the router... and secondly, the firewall on the laptop.

Try using a set of DNS servers from somewhere outside... and are a good set of servers to test with.

Did you try entering the ip settings manually, including the DNS servers? Looks like a DNS server problem. Try entering your gateway's address as the DNS server, it'll know where to look most of the times. Of cours try setting those settings in the wireless card's properties! You may even want to disable the wired ethernet card to make sure it works.

Verify that "Block Anonymous Internet Requests" is not enabled on you wireless router.

I finally did a repair install of windows and got back the wireless connection.  Since I'm not sure exactly what did it, splitting points.
