I have a Gateway M- 7351U laptop. The wifi keeps telling me that it is off even when I turn the external switch to the on position. I have tried using fn f2 but it has done nothing. A friend recommended manually trying to turn it on by going to the mobility center but when I did that the option for turning the wifi back on was greyed out so I could not select it. Please help!!

So nothing changes when you have the switch on and you use the Fn+F2 key combination. This might indicate there is a problem with the wireless card. If that is the case and you are not comfortable opening up your laptop to replace it then you might want to consider a wireless dongle like this one - http://www.newegg.com/Product/Product.aspx?Item=N82E168... (2 year warranty) or this one - http://www.newegg.com/Product/Product.aspx?Item=N82E168... (3 year warranty). There are more wireless USB adapter options and a search of Amazon or Newegg or TigerDirect will help you find one.
