ip not being assigned by router

[grizzly]

I was wondering whether bad drivers could be responsible for dhcp problems.
Here's what is happening:
new laptop with vista, no xp drivers . Found a driver for atheros ar5006eg card from windows update.
Now I can connect to a d-link wireless router if i assign a static ip address to the wireless network adapter, but if I switch to DHCP I get -

" limited or no connectivity. "this problem occured because the network did not assign a netowrk address to the computer"

With the exact same configuration on the same laptop I can connect to the laptop wirelessly with vista. Currently I am connected to the router with an ethernet cable on xp

So could this be a bad driver or is there anything else I should check ? and if it is a bad driver , then is there any site where I can try a few drivers?

Things i have checked: wireless antenna is on , dhcp is running, signal strength is excellent.

Thanks

Check the network card driver status from device manager, make sure it's working well. If not, uninstall and reinstall with the latest driver, you can get the latest driver from the wireless adapter's vendor website.
