OK, last night I was randomly cut off my wireless network.. Thought it could be a temporary problem so just slept it off, woke up again this morning and I've not been able to connect my laptop to the wireless network. I've even come down to the host computer and placed my laptop next to it, to see if the signal was any better.. and it is just non existant.

I click on "wireless network connection" and refresh network list and it just "no wireless networks were found in range" and whenever I click refresh network list it just comes up with the same message straight away.. Not allowing it to search. I'm so worried it might be something to do with my laptop because I am going to uni next week, so NEED wireless when I am there.. It's so annoying!

Any ideas on what I could do?

Oh my god, like a complete mug it was the wireless button that had been pressed in or something.. I didn't even know my laptop had a wireless button!

lol - glad you found it....
