My new Toshiba A660-18n wireless networking didnt work even straight out of the box,
I was told everything from a faulty machine to faulty drivers.

But then I did a little investigating myself, and discovered the solution, its very simple

go to the following folder on your C: drive

c:\program files\toshiba\tbs

and double click on the file called "Tbs Wireless.exe"
(It has a little icon of an aerial on it)

This will pop up a brief message.

Then press Fn and the F8 Keys together until the little orange light comes on on the lower front right of the computer.

and hey presto, the wireless system will now work.
Its a bit strange how Toshiba didnt spot this flaw.
