On a dell mini 9, I have installed ubuntu 12.10 to a 32gb ssd. The wifi is not being found and I think it has something to do with the network adapter. The wifi is definitely working on other computers and I'm sure it's not there in my laptop. I installed Ubuntu using a USB.

I've got a bunch of mini-9 machines, the broadcom wifi cards in them can be a problem on linux. I would try doing a full update on ethernet, then running "Addition Drivers" (jockey-gtk) to add the proprietary Broadcom driver. – Veazer Nov 21 '12 at 19:48
How do you mean 'a full update on ethernet'. I'm not that experienced with Linux or computers generally and so I don't really know how to. – Louis Nov 23 '12 at 16:01
When I type in jockey-gtk into Terminal it comes out with The program 'jockey-gtk' is currently not installed. You can install it by typing: sudo apt-get install jockey-gtk When I type that into terminal it comes out with Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package jockey-gtk Help? – Louis Nov 24 '12 at 12:09
Every time I try to install something (like 'Additional Drivers'), it just says 'Failed to download repository information', and to check my internet connection, even though during the installation I checked my internet on Firefox. – Louis Nov 24 '12 at 17:04
