Sorry, for some reason, perhaps the link, caused your post to get caught in the moderator's queue and I missed it for a couple minutes.
Looks like the one that I edited and added to my post above.
Anyway since you report that device manager seems to think that both your wired and wireless adapters are working fine....
You may want to try resetting the Winsock Catalog as well as the TCP/IP Stack, try this;
To reset Winsock for Windows Vista, follow these steps:
Click the start orb, type cmd in the Start Search box, right-click cmd.exe, click Run as administrator, and then press Continue.
Type netsh winsock reset at the command prompt, and then press ENTER.
Note If the command is typed incorrectly, you will receive an error message. Type the command again. When the command is completed successfully, a confirmation appears, followed by a new command prompt. Then, go to step 3.
Type exit, and then press ENTER.

The reset command is available in the IP context of the NetShell utility. Follow these steps to use the reset command to reset TCP/IP manually:
Click the start orb, type cmd in the Start Search box, right-click cmd.exe, click Run as administrator, and then press Continue.
At the command prompt, copy and paste (or type) the following command and then press ENTER:
netsh int ip reset c:\resetlog.txt
Note If you do not want to specify a directory path for the log file, use the following command:
netsh int ip reset resetlog.txt
Reboot the computer.
When you run the reset command, it rewrites two registry keys that are used by TCP/IP. This has the same result as removing and reinstalling the protocol.
