I installed Ubuntu 13.10 beta 2 on my ASUS G55V and during install the internet (wireless) connected perfectly fine and downloaded updates.

After install, it was connected for a couple seconds until saying "disconnected"

It was still being recognized, but it would NOT connect.

I then looked online and seen people saying to add/remove things in


but I ended up screwing it up some more. I also ended up removing network manager as a whole as described online.

How do I get the internet working again? Neither wireless or ethernet work.

  • Try sudo ifconfig wlan0 up and revert /etc/network/interfaces back to normal.

In a terminal do this:

sudo sh -c "cat > /etc/network/interfaces"

Now copy the following text:

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

Press Ctrl + D. Now restart your system and it should be back to normal.
