I upgraded to 13.10 but now my laptop won't connect to wifi any more. I can see there are plenty of questions and answers around but my biggest problem is that I've only been using ubuntu for about a month and before that it was all windows and honestly I have no idea what I'm doing. Except to restart, I restarted. I wouldn't mind going back to 13.4 but I don't know how to -_- I can connect with a wire (and stay connected wirelessly for a while after that O.o) but that's it. I... also don't know how to check what my wireless card is. Clearly I should have waited with the upgrade but it's late for that advice now so, can anyone help?
