RTL8723DE wireless support

Post by stewschneider »

I bought a anew HP and I'm trying to install LM Tessa with the 4.15 kernel. There seems to be no support for this wireless card. After a bit of searching I found some instructions, but it requires the 4.17 kernel. I'd like to demonstrate that everything runs correctly from the USB drive before I wipe the disk on the laptop. Can anyone help?

In terminal check mokutil --sb-state as Secure Boot needs to be disabled in BIOS, don't delete the Secure Boot keys
Then do

Code: Select all

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
Reboot

That's very helpful. Thank you. Two quick questions: 1) I'm still running off the thumbdrive. Can I do this without installing to the hard drive?
2) What about the concern over the 4.17 kernel version?
Many thanks in advance

I am not sure if it can be done from the thumdrive and the stories about kernel 4.17 are false. If Mint is installed to the hard drive the instructions I gave work in the 4.15.0 kernels that Mint uses, they will get security updates until 2023
