I purchased a Toshiba laptop in 2012... it’s been great. I’ve had no issues. However, now, I cannot get it to connect to the internet! I have tried the FN-F8 approach. It just shows that the connection is disabled. It will not allow me to right click to enable. I also, tried to use the connection switch located at the top of the keyboard. It makes a noise & the light comes on! However, it does not connect to the internet. What is going on, here? Helppppp please! It is insisting on using the switch... but the switch is not cooperating!
