I brought Dell Inspiron N5050 few months back. from day 1 i am getting problem with wired connection, i am able to use web browser for few minutes then all of the sudden i lost internet connection but i don't know why transmission is still able to download torrent from internet.
I just got my Wi-Fi internet connection up & running earlier today using this thread on Ubuntu 14.04 LTS (64bit). Unfortunately, even though my connection appears to be up & running, I seem to have difficulties staying connected to the internet. Shortly after beginning downloads or high volume browsing, my connection appears to lose connection to the internet.
