Yesterday my laptop (ASUS E200HA) was upgraded to 18.04.2, but now the WiFi doesn't work. I've tried following just about every instruction for 10 hours now and still no joy. Bluetooth works, which is how I'm connected just now.

  • Another whole day trying to resolve this - is there another update coming out to correct the last update? I'm so fed up with this I'm on the verge of going back to Mint :(

  • try sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/* and reboot, wifi power management might be causing the driver to crash

  • Thanks @Jeremy31 tried that but sadly no joy. Still no wifi adapter found.

Yesterday my laptop (ASUS E200HA) was upgraded to 18.04.2, but now the WiFi doesn't work. I've tried following just about every instruction for 10 hours now and still no joy. Bluetooth works, which is how I'm connected just now.

  • Another whole day trying to resolve this - is there another update coming out to correct the last update? I'm so fed up with this I'm on the verge of going back to Mint :(

  • try sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/* and reboot, wifi power management might be causing the driver to crash

  • Thanks @Jeremy31 tried that but sadly no joy. Still no wifi adapter found.

Yesterday my laptop (ASUS E200HA) was upgraded to 18.04.2, but now the WiFi doesn't work. I've tried following just about every instruction for 10 hours now and still no joy. Bluetooth works, which is how I'm connected just now.

Yesterday my laptop (ASUS E200HA) was upgraded to 18.04.2, but now the WiFi doesn't work. I've tried following just about every instruction for 10 hours now and still no joy. Bluetooth works, which is how I'm connected just now.

  • Another whole day trying to resolve this - is there another update coming out to correct the last update? I'm so fed up with this I'm on the verge of going back to Mint :(

  • try sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/* and reboot, wifi power management might be causing the driver to crash
