I am running a dell inspiron 1501. When I booted ubuntu in my computer and could not find wifi. So i found this thread: can't find wifi on newly installed ubuntu 14 Which I believe will solve my answer(the answer on the forum was to update driver using ethernet cable). However when I plug in the ethernet cable, its not getting any internet connection. I have tried 2 cables each in different ports on the router and still doesn't work. 1 computer is getting internet from the ethernet connection from the router indicating the router does work. How do I get ethernet connection working! By the way i recommend reading the forum for more information on my problem. Please Reply ASAP!

You installed a wrong wireless driver that does not support your wireless adapter and blocked your Ethernet card.

You can fix it this way. Run in terminal

sudo apt-get purge bcmwl-kernel-source

and reboot. Your Ethernet card will start working.

After that connect to the internet by wire and install the correct wireless firmware by

sudo apt-get install firmware-b43-installer
