Thanks for the advice t_ski, Crap Daddy and Random. I'm sure I'd be finding this all very useful when I get back at home tomorrow.
On "default" I still couldn't get online though from the cellphone. I'm assuming that was 'my' connection, since 'BlackPanther' didn't appear.
What's weird is that the pc can see the router but it's not called Edimax anymore

but NU11 or something similar...
I googled NU11 and apparently it's a wireless adapter. I haven't got any of the sort.
Edit: Thanks brandon I just saw your post. I will try that tomorrow as well.
Thanks everyone for the help, much appreciated!
