I have an hp 15-ac110tx and dual booted with Ubuntu and Windows 10 in UEFI mode with secure boot off. All the things are latest updated and upgraded. But WiFi frequently disconnects.
The output of this command:
wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \ chmod +x wireless-info && \ ./wireless-info
is as follows:
