Automatic wireless reconnection after Vista restart

[Miltongomes]

I am helping a friend setup a home network. I have got a new Belkin N Wireless router (F5D8233-4) set to:
Authentication: WPA-PSK + WPA2 + PSK
Encryption: TKIP + AES
Unique SSID and pre-shared key entered
I also have a new HP Pavilion DV6000 laptop running Vista Premium. Built-in 'G' wireless adapter (Atheros). The driver is the latest version. Using the regular Vista network setup tools, a stable wireless connection can be established with the configuration described above. The problem is that the wireless connection to the private home network fails to automatically re-connect following a Vista restart. The wireless connection can be successfully re-established by disconnecting from the private home network followed by a 'connect' to the same private network. This process does not require entry of the pre-shared key.

Ayn solution?

Can you please post an ipconfig /all from that computer when it is in the "bad" state

This issue occurs because of a difference in design between Windows Vista and Windows XP Service Pack 2 (SP2). Specifically, in Windows XP SP2, the BROADCAST flag in DHCP discovery packets is set to 0 (disabled). In Windows Vista, the BROADCAST flag in DHCP discovery packets is not disabled. Therefore, some routers and some non-Microsoft DHCP servers cannot process the DHCP discovery packets. More information here - http://support.microsoft.com/kb/928233/en-us
