Hi friends,
I can't enable Wi-Fi. Do I have any wireless devices? If NO, what should I do?

Other devices (android os) work well. Any Ideas? Thanks in advance.

Thread moved to MINT as the more appropriate forum.

Please post your output between [CODE] and [/CODE] tags for clarity. Or highlight the output and use the button in the *Adv Reply* toolbar.

Also, please refrain from using nonstandard fonts/styles because many forum members must view from mobile devices or have vision restrictions.

sudo apt-get install dkms git build-essential
git clone -b extended https://github.com/lwfinger/rtlwifi_new.git
sudo dkms add ./rtlwifi_new
sudo dkms install rtlwifi-new/0.6
sudo cp -r rtlwifi_new/firmware/rtlwifi/ /lib/firmware/rtlwifi/
echo "options rtl8723de ant_sel=2" | sudo tee /etc/modprobe.d/rtl8723de.conf

Check [c]mokutil --sb-state[/c] as if it says Secure Boot is enabled, you will need to disable Secure Boot in BIOS/UEFI when you reboot, don't delete the Secure Boot keys
