I have Ubuntu 12.04. I was downloading something via Aria... and then it suddenly stopped. There was no connection to the Internet.
I tried to ping the host but there was no reply. Also tried to ping the route 192.168.250.1 but there was no reply. I got a message saying 'Ubuntu 12.04 has experienced internal error'.
I restarted system but nothing was sorted out.
The wired connection 'establishes' but I am not able to use Internet or ping either to host/route/18.104.22.168.
The wireless is working fine and it does connect to Internet. I have a static IP address for a wired connection and it connects to Internet on Windows OS installed on the same laptop with same IP settings.
Please suggest how I can get my wired connection to start working properly again.
