[SOLVED] No Wifi in Linux Mint After it Had Been Working — Why? How Can I Fix It?

Post by mintyfreshuser » Wed Jan 10, 2018 3:01 am

My Wifi stopped working but it had previously been working just fine. I’ve been using Linux Mint for over a week with no Wifi issues so I don’t understand why this would happen now.

I had to use a USB Wifi dongle in order to post this. The USB Wifi dongle works as it should, but why doesn’t my computer’s built-in Wifi work anymore?

The distro of Linux Mint that I’m using is Linux 18.3 Sylvia and the desktop environment is Cinnamon 3.6.6 if that helps.

 echo "options rtl8188ee swenc=Y ips=N" | sudo tee /etc/modprobe.d/rtl8188ee.conf

I suspect that the last update you did included and kernel update and that is what might have caused the problem.
good luck.

Not sure why wifi is hard blocked?! I was using it normally in the morning and afternoon without any update wifi didn’t want to start up. I was trying to turn it on and off in BIOS but nothing has helped.

When i left click on network icon and try to turn it on switch button do not want to move it is just »slipping». When i go to network settings wifi switch goes on but then after some time it goes back off. :/

Not sure what is a problem.

Please help me somehow. Thanks a million.

Linux mint wifi недоступно

Добрый день!
После установки LM 19.3 x64 Cinnamon 4.4.8
Подключение к интернету только через провод, судя по всему WiFi адаптер не работает. Что я не так делаю? Сразу скажу, что Линукс для меня случился впервые, прошу отнестись с пониманием.

YuNo , Ещё одну вещь забыл , может он выключен . Увидеть можно rfkill list
И вдогонку , проверь в биосе secure boot , при включенном не установится ни один проприетарный драйвер.
