Turn on WiFi on Windows 7 to fix laptop errors not found WiFi network

On a beautiful day, you turn on your laptop and suddenly because of a list of WiFi networks, the laptop doesn't find any WiFi networks? What the hell is going on, I still use normal last night, WiFi is still full.

If the laptop just can't find a WiFi network, the problem is likely to be in that WiFi network (lost the network, the router is turned off, the network cable connected to the modem / router breaks, slips, .) but if the laptop doesn't Find any WiFi network, think of WiFi on your laptop.

I met this case on a computer with Windows 7 installed, after accidentally pressing a combination of keys, it showed up a small frame on the screen but was in a hurry to turn off the computer, so I turned it off (at a hurry, I don't know how to press right off button no more) without reading what it is. The next time you turn on the device, no WiFi networks will be found.

Then adjust the Adapter settings, run the Windows debugger, update the driver, scan the virus for all types, add the WiFi network manually and not lose. Press both the WiFi key on the keyboard and not. Finally, I found a way to turn on WiFi on Windows 7 and that damn error has disappeared.

Through research, I found that, most Acer laptops can turn on / off WiFi via keyboard shortcuts, some other laptop companies have the switch to turn on. If you have used these hard keys to turn on WiFi without working, the laptop still can't find the WiFi network, so the switch to turn on WiFi with the software is turned off, follow the instructions below to turn it on. ok
