Hello,

I post this information I got on internet because it was hard to solve
that problem.

Model computer: Sony VAIO VGN-N21E/W SW1 (Swiss Model)

Operating system: Microsoft Windows Vista Home Premium

Wireless card: LAN-Express

Access Point: SonicWall

Problem: The problem come from the new tcp/ip stack integrated in
Vista.. I couldn't get any IP from a DHCP server. I could see the
Access Point and connect my laptop on it but never get any IP from my
DHCP server.

How to solve: You have to modify a key in the registry to make your
Vista able to get an IP from your DHCP server.

1. Click the Start button.
2. Select All Programs > Accessories.
3. Right click Command Prompt and click Run as administrator.
4. Type regedit.exe and press enter.
5. Go to the following location: HKEY_LOCAL_MACHINE\SYSTEM
\CurrentControlSet\Services\Tcpip\Parameters
6. Right click this entry and select New Dword.
7. Rename the new entry ArpRetryCount (leave it set to 0 by
default).
8. Restart the computer.
9. Reassociate with the SonicWALL. You should notice a successful
connection.

Hope it can help people.
