I don't see that particular line in my /boot/grub/grub.cfg on LM18.3 or LM19.3, so assume it must be unique to LM20 which I don't have installed. Anyway, the grub.cfg file is built up from, in addition to the /etc/default/grub file, some files in /etc/grub.d - in particular take a look at /etc/grub...

I think that setting involves network devices specified in /etc/network/interfaces, if managed=false then network manager will not manage that interface

See if removing the internal wifi card helps. You might need to reset BIOS settings if that doesn't work

That worked! Thank you for your help :)

Can I ask what it was that needed fixing?

Or did you disable Secure Boot in BIOS settings?

The chart at https://wireless.wiki.kernel.org/en/users/drivers/b43 shows that only the proprietary module works for that device

Try

Code: Select all

echo "blacklist asus_wireless" | sudo tee /etc/modprobe.d/asus_wireless.conf

Reboot

Code: Select all

dkms uninstall rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414
dkms remove rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414 --all
sudo rm -r /usr/src/rtl8723de-5.1.1.8_21285.20171026_COEX20170111-1414
cd rtl8723de
git pull

See if it updates anything, some of those errors were from older code

Mint 17 is no longer supported. If you can change the channel the wifi is on, I would change to channel 1-11 and see if Mint can find it then

Lets see the errors on the build

Code: Select all

cat /var/lib/dkms/rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414/build/make.log

Maybe you can turn wifi on in Bios or reset to defaults. Did check BIOS, early stages of this project, no real option of enable or disable. Other BIOS may & often do offer this option. However your mention of BIOS brings up another possible option upgrade current version F.35 to F.37 Thank you Go i...

Try this before anything else

Code: Select all

echo "options asus-nb-wmi wapf=4" | sudo tee /etc/modprobe.d/asus-nb-wmi.conf

Reboot, check rfkill list and see if anything is hard blocked, if it is try the FN combo again to see if it gets unblocked
