Wireless drivers on GitHub

I have a new HP laptop with a Realtek d723 wireless adapter that is not recognized but my question is not how to fix it.
I see several other threads for the same (or similar) issue and many of them point to installing drivers from
https://github.com/lwfinger (or one or two others, e.g. smlinux). I can go ahead and try that but first I have to ask who is this person and where did the code come from? I haven't been able to find any answers so I hope someone can clue me in.
I certainly don't want to cast false aspersions; more than likely everything is on the up-and-up but I feel some need to understand a little more before blindly installing these drivers.

Thank you! That's probably as good an answer as I could have hoped for. I imagine it also means these drivers may make their way into the kernel at some point.
I do have one more question. lspci -knn reports the wifi adapter as
Code: Select all
02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:d723]
Subsystem: Hewlett-Packard Company Device [103c:8319]
I think another name for this device is RTL8723DE. Is that correct? How could I have known that?

You can Google the device ID:
https://www.google.com/search?q=10ec%3Ad723
Note that you need to install the
extended edition of lwfinger's driver. Here's a how-to that I've written for installing it:

(item 8, right column)
As it's an HP laptop, you might also need to fix the antenna selection:

@Pjotr, TYVM! I did notice that extended branch. I think I've found three repos with this driver, lwfinger, smlinux and jeremyb31. I'm not sure what the differences might be, or if there is a preference.
Thanks again, I really appreciate all the work you and other folks put into this. I've used your site a fair amount!

I am fairly certain that my code for rtl8723de will not work with the 4.15 kernel and I know lwfinger's does work

@JeremyB, I've just installed LM18.3 Cinnamon and updated to the 4.15 kernel. I'll try lwfinger's driver next and will report back. Thank you!

All went well and wifi is working now, but I think I need to check the antenna options. I'm only seeing my SSIDs and usually I see several others here in the neighborhood. I also only see my 2.4GHz SSIDs, no 5GHz. That's not a show stopper for me but 5GHz would be nice.
When doing the make, I noticed the message
Code: Select all
Makefile:976: "Cannot use CONFIG_STACK_VALIDATION=y, please install libelf-dev, libelf-devel or elfutils-libelf-devel"
but none of these packages seem to be in the Mint Software Manager. Do I need to install one of them?

Those errors can be ignored

Can't see 5GHz networks from Windows either, so maybe the RTL8723DE is only capable of 2.4GHz?
Edit: I see that according to
the Realtek web site it is 2.4GHz only.

Larry Finger's driver and ant_sel=2 did the trick (used Pjotr's instructions), things are looking very good. Not a bad little machine (inxi below). On sale at Staples for $349. My wife was looking for something smaller and lighter. Just a Core i3 but it seems plenty fast. Next step will be to ditch Windows completely and make it a Linux only machine
Thanks again for all your help, you guys rock!

Contrary to the advice on Pjotr's website
I installed a new kernel, upgrading from 4.15.0-29 to -30.
I thought just reinstalling the driver (sudo make install) might be enough. It was not, but the following worked:
So really not too bad
