I'm using "Dell Vostro 5490", OS Ubuntu 18.04, Wifi module "Intel(R) Dual Band Wireless AC 9462".
For two months everything worked well. Once after update I reboot Dell and Wi-Fi adapter is not visible anymore. In the "Settings" I see message "No Wi-Fi adapter found".
sudo rfkill list shows Bluetooth only
dmesg shows Detected Intel(R) Dual Band Wireless AC 9462, REV=0x354
I tried to use answer from here and it works. However, then I had another update of Ubuntu and needed to reboot. After another reboot Wi-Fi didn't work again.
I tried again the same answer. Before make install I run git pull origin master. After that during reboot Ubuntu just stuck. From the root mode I just run make uninstall in backport-iwlwifi. Now Ubuntu works, but without Wi-Fi.
Did anybody encounter this problem? Can you give any solution or advice?
