    What source code did you use? What are results for
    Code:
    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.

    Code:
    taylord@TaylorD:~$ sudo apt install make
    Reading package lists... Done
    Building dependency tree       
    Reading state information... Done
    Package make is not available, but is referred to by another package.
    This may mean that the package is missing, has been obsoleted, or
    is only available from another source
    
    E: Package 'make' has no installation candidate
    taylord@TaylorD:~$
    I'm connected via ethernet and using the laptop to post this, so I know it's not a network issue.

    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
