In summary : I can see and connect to to my home network via wifi (entered password), however on Mozilla impossible to load any internet pages, or even connect to my router via

I'm not sure it's the same issue as the post in your comment. See my output for "modinfo p54usb" above. –  DWryly Feb 21 at 20:28
Also, as I mentioned, I'm a complete novice. So even if the issue is similar, I have no idea how to adapt it to my problem! –  DWryly Feb 21 at 20:30
I just ran sudo apt-get install linux-backports-modules-cw-3.6-precise-generic. Don't know if it applies to me (3.6 vs my 3.11) but it may have worked. If you can see this comment, then it appears it will have. –  DWryly Feb 21 at 20:40
