Qualcomm Atheros QCA9377 [168c:0042] subsystem [17aa:0901] not available in Ubuntu 19.10

[Anonymous User]

I have installed the ubuntu 19.10 and since the installation it says no wifi adpter found but the wifi was working with Windows perfectly but since I switch to ubuntu I am not able to use the wifi. I have tried lots of different methods to fix this issue on the internet and also asked on Ubuntu community for help but none worked for me. It seems there's some bug on the os because during the installation the wifi was working but after the installation has completed the wifi stoped working and says No wifi adapter found.
