|Well, you've ruled out the cable so that just leaves the network interface on the computer. You've already tried updating the drivers so the next step would be to reset the TCP/IP stack. To reset your TCP/IP stack first open a command prompt window (ie: Start >> Run >> type cmd and hit Enter) and perform the following command:|
netsh int ipv4 reset c:\resetlog.txt
(change ipv4 to ipv6 to reset IPv6 in Windows 7 – in Windows XP, all you need is “ip”)
If you do not want to specify a directory path for the log file, use the following command:
netsh int ipv4 reset resetlog.txt
Then reboot the computer.
If that doesn't do the trick, the last thing to do is to remove the device in Device Manager and then let Windows "find" the device again and reinstall it.
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.
