After attempting to use a VPN client (Astrill), I can no longer access the internet through my Ubuntu installation. The VPN was setup as piece of software, not something to be used through Ubuntu settings.
Its not a network issue, as on the same Wifi and wired network both my Windows install and other comps can connect and use the network.
I can, however, connect to sites via a proxy client running through WINE. I've tried changing proxy settings, but to no avail. I'm really at a loss and have no idea what I should do,
Whenever I try to run Firefox, I get almost immediately "Unable to connect" and when I try to update (
sudo apt-get update) in the terminal, it immediately comes back with cannot find. There isn't a moments hesitation, just bam! can't do it!
