Realtek RTL8723DE Wireless Card and 18.04

[shanasman450]

Is anyone who has a Realtek RTL8723DE wireless card currently having any issues with connectivity?

What source code did you use? What are results for

modinfo -p 8723de; modinfo -p rtl8723de

I'm not currently on 18.04, my bad if I made it sound that way. I'm actually on 16.04 and had wireless issues that I fixed with a driver. I'm mainly trying to find out if this issue still persists with 18.04 and if it is still just a driver issue. If that's the case I'm going to go ahead and grab the iso and install it.

Well, I decided to just go ahead and install 18.04. I'm wishing I hadn't now. I have the needed driver for the wireless card, but when I cd to the driver file location I can't use make/make install because make itself has to be installed. Problem is, I can't install make. I get this.

I'm connected via ethernet and using the laptop to post this, so I know it's not a network issue.

Try

sudo apt update && sudo apt install build-essential

Thanks, that did it.

That didn't do it for me. Modprobe gives error:
ERROR: could not insert 'rtl8723de': Required key not available

Go into BIOS settings and disable secure boot
