|You might want to start by checking to see if there's a newer driver for your wireless device. If there is, install it and see if your computer can't see wireless networks then.|
If that doesn't work, you may have to reset the TCP/IP stack as per the following instructions:
To reset your TCP/IP stack first o pen a command prompt window (ie: Start >> Run >> type cmd and hit Enter) and perform the following command:
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
Then reboot the computer.
If that doesn't do the trick, you might have to completely uninstall the wireless interface and then reboot and let windows "find" and reinstall it.
If none of the above works, you will probably have to take it in for servicing with a qualified repair depot.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
