Hi, we need you to detail some more.
1. Do you mean Wi-Fi adapter still appears, but you fail to connect to
existing WiFi networks that used to connect to? You mentioned the WLAN
is still visible and you're able to enter WLAN SSID/passphrase.
2. Please attach system journal again against the failing kernel
4.15.0-96+ and 5.3.0-28+. We need to know what happen when you upgraded
to new kernels. You may have no network access then, so you can run
following commands to save logs and attach them later when rebooted back
to 4.15.0-96:
$ sudo journalctl -b 0 | tee journal.$(uname -r)
This will create one journal.* file at your present working
directory. So reboot to 4.15.0-96+ kernel, run the command once, and
then reboot to 5.3.0-28+ again, and run that command again as well.
Attach both files as attachments here please.

Title:
Ralink RT2790 [1814:0781] Subsystem [1462:6890] wifi card lost
function
Status in linux package in Ubuntu:
Confirmed
Bug description:
The kernel 4.15.0-96 is the last working one with my WiFi card. The
same problem occurred with kernels larger than 5.3.0-28. My first
thought of a hardware failure due to a low or empty BIOS battery was
not confirmed. The laptop is a dual boot with Linux Mint 19.3 as first
system and Win 8.1 as second. Win 8.1 did not show these errors. It is
also not my first choice. The non-functioning kernels can't find my
WLAN anymore, the neighbors can. Even re-entering the SSID and the key
does not help. The WLAN is visible.
