Title: Can't connect to Wifi connection(Wifi gone in network manager)
Hi

I can't connect to Wifi connection(Wifi gone in network manager) in Lubuntu.
I can correctly connect with ethernet but it doesn't connect to wifi or pick up any wifi connection or device any more.
Wifi stopped being picked up just after I did some Lubuntu updates and restarted it.

I am using dual-boot Lubuntu firmware.
I did so many customizations, would be very sad too loose everything just to reinstall firmware for working wifi.

Are there terminal commands I can try or uninstall/reinstall network manager to get it to pick up wifi again.

Please help.

Firstly, you should run
sudo ifconfig -a
to list all the network inferaces.

Then do a WiFi reset:
sudo /usr/local/bin/wifi-off.sh
sleep 3
sudo /usr/local/bin/wifi-on.sh

Check the network interfaces again:
sudo ifconfig -a

View kernel log:
sudo dmesg

Please post the result here.

Thanks

I recopied the wifi firmware files AP6335.bin etc. from here - https://github.com/gouwa/hwpacks back and it worked.
Somehow after a 'sudo update' the wifi firmware files went missing.
