I have a sony vaio VGN-AR51J, my wireless was working fine until I turned it off the other day, now when I flip the switch back to the right [on] the wireless light does not come on??

the laptop cant find any wireless networks and when I trouble shoot it tells me the wireless switch is turned off!

I'm not that great with laptops but I've looked on the internet at some of the solutions people have tried with their wireless connection but none have worked for me!

is here anyway I can fix this myself or do I need a new switch?? help please!!!!

Thank you in advance
