My laptop was running smoothly until yesterday. Today, I can't connect to the Internet at home anymore. I am only able to access the router, but no Internet access.
A have a Dell Latitude E6320 with Ubuntu 12.04. At my job, I don't have any problems connecting this laptop both via Wireless and Ethernet. At home, if I try connecting it through Windows, it does work fine. I even checked the MAC address and it's OK.
My other laptop, which also runs Ubuntu, is not facing this problem.
I have already tried to restart and downgrade
network-manager package and its dependencies.
Can anyone help me please? I am afraid, I will have to reinstall everything.
