DHCP fails on WLAN

Hi all

I've got a brand new Levono T61p (running Vista Business) with a WiFiLink
4965AGN and am trying to connect to a Zyxel G-2000plus v2 with DHCP. The
WLAN card does request an IP, the Zyxel does associate the card (MAC
address) with an IP temporarily, but the card then seems to discard the IP,
because the DHCP association disappears again from the Zyxel status page.
Finally, the WLAN card gets a MS home IP address (169.x) and shows 'Limited
Connectivity'. I've installed KB941649, and have tried out the registry fix
of KB928233. KB932063 does not appear to address my problem, so I haven't
requested that update.

Any ideas?
Thanks a lot

Actually, KB928233 does the trick. It's just important to note that below
the "RESOLUTION", there's a "MORE INFORMATION" section with an additional -
important - registry hack.

Cheers
