No Wifi

I picked up an older Acer Aspire 5250, Win. 10, am not getting a WiFi signal, when I hit the icon, says WiFi not connected, I go to the WiFi icon and it is off, but after trying the on/off choice it does not turn on. Help!

 

Are you pressing the fn button as well ?

 

It may be the windows button , instead of fn, but usually pressing fn +f3 button together should work

Many notebooks have a separate button to instantly disable wireless. Look for it - often along the front edge. Also you typically can quickly disable the wireless using the correct Fn + F-key combination. There is no industry standard for this. On my Toshiba, it is FN + F8. This basically puts the notebook in "airplane" mode. This should be in the manual, or just look at the keys for an antenna icon.
