I am using Lubuntu 18.04. I am unable to connect to my Wi-Fi network. I just happened since an hour ago.
In my edit connections options it is showing my Wi-Fi name:
VodafoneMobileWifi-51BB
which was last active 1 hour ago.
My Enable Networking and Enable Wi-Fi options are checked.
But my laptop is suddenly unable to connect to the network.
My Wi-Fi adapter is Qualcomm Atheros QCA9377
I followed the instructions given in the first answer of this askubuntu question
sudo make defconfig-ath10k
gives me the prompt:
