Lately I switched off the WLAN on my laptop, but it can't be switched on since then.
I've restarted the laptop several times, have already updated the driver of the wireless adapter. I have also restarted the wireless service under the control panel. That did not work. Do you have any idea what else I could try?
For information: I have an MSI GT70. The wireless adapter is called "Killer Wireless-N 1202 Network Adapter" and is from Qualcomm Atheros Communications.
The wireless key on the notebook keyboard already tried?
Let's start at the top: device type and operating system?
then it would be good to know HOW you have switched off the Wi-Fi, after all, there are several options.
It has just finished by itself. My guess is that the driver update I've just done took a while. So the mistake was that the drivers of the WLAN adapter were not up-to-date.
