No Internet Connection after Vista SP2 upgrade

[Chioke]

I have upgraded a laptop with Vista 64 SP2 last week. Seems to have retained my 802.11n network settings, but since due to the update only I can connect to local network, can not to the Internet. I have checked there is not a trouble with my network or modem, and another laptop with Vista is working properly. Ethernet connection seems works very well. If any solution please let me know. Any kind of help would be appreciated.

That sounds exactly like my problem. Although I do not understand what happened, I found a solution. Try this: Log on to the router and see what IP address is assigned to the computer that is not connecting. If no task, however, assign a static address. Go to Properties of TCP / IP for the wireless connection and enter manual configuration information: the assigned IP address, subnet mask and address of the router and default gateway. To me, that allowed me to connect via the Internet.

At primary,Enter into the settings manually following every reboot, and router does not properly recognize the MAC address of laptop which. Following some original start the night by, the panel would keep the settings, so you can connect with not having to enter the configuration, the router but silent no MAC address list present. After updating router's firmware. D-Link DIR-655 Now, restart again, the whole thing appears to doing appropriately with a laptop correctly recognized on the router. There was obviously a issue with the network adapter and the router communicating properly.

This is very strange. I know you said you already update the driver but try to remove the driver completely, reboot. Allow Windows to download a new driver for your wireless network. Also try another network card to see if you can solve the problem. Can a list of protocols and services available in TCP / IP for the wireless connection . I would still like to resolve this works so well by default. Thanks again for your help. Any more suggestions are welcome.
