Above are the information about our system.
I installed LMDE 6 on my Acer Aspire 5 A515-51G-54AW laptop with UEFI and secure boot disabled.
While installing the wifi detected my home router and I so I was connected during install.
Post install post reboot, I could still connect to my home router and downloaded many things and updating the drivers was one of the things I did.
Since next morning the wifi is detecting whole building's routers except my home router. I even tried to switch on my mobile hotspot and that as well not getting detected.
I saw that the network card i have is Qualcomm Atheros QCA9377 and so I did tha following:-

sudo apt-cache search qualcomm

sudo apt install firmware-atheros
I tried removing it and installing again and rebooting, but it did not solve the problem.
Then I decided to upgrade linux kernel using backport so I did and got the latest version installed by the following command
Code: Select all
sudo apt install -t bookworm-backports linux-image-amd64
I read every post about wifi not working on LMDE 6 available here and nothing seems to help.
I DONT WANT TO GO BACK TO WINDOWS.
Please help, any help will be hugely appreciated.
