Hi, Please refer to http://support.microsoft.com/kb/928233/en-us The problem is the BROADCAST flag in DHCP discovery packets different in Vista vs. XP SP2. And for me the solution was to set the following registry entry as follows: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID} Value name: DhcpConnForceBroadcastFlag Value type: REG_DWORD Value data: 0 After that, please manually remove the Wi-Fi card from the computer and restart.
