unindentified network - no default gateway

[AnonDN]

Try to uninstall/reinstall your network adapter from Device Manager.

Any Security/Firwall Software installed in your computer?

Let's try repairing the TCP/IP and Winsock. If this doesn't work for you then it might be worth replacing your network adapter.
Click on Start=> All Programs => Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.
Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log press enter
Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log press enter
Reset WINSOCK entries to installation defaults: netsh winsock reset catalog press enter

Restart the computer after.

Please let us know.

I have the same problem and this doesn't work for me (Reseting IP & etc.) :/
