The following happened.
My laptop was connected normally, just like the smartphone. I have not looked at the laptop for about 10 minutes and when I looked back on it was only displayed (following picture). In the network settings I'm the menu point wlan garnichtmehr displayed.
On the smartphone, there are still no problems! Wlan is running perfectly.
Did you accidentally shut down your Wi-Fi?
With Lappis there's a normal button for it… Me already happened
Otherwise, go to the settings for Internet connections and call the self-diagnosis. After an update (some are so small that they are not displayed extra) sometimes they change
If I had to guess I would say Windows has tried to update the driver for the wireless card and has verkackt properly.
Have you ever tried a reboot?
If that does not help you have to plug your laptop with a cable on the router and download the wlantreiber from the website of the notebook manufacturer and install.
You should restart. But hope that the laptop does not hang when rebooting like my previous laptop, because otherwise it is no longer on.
