I have a tp-link ac1900 archer T9UH wifi adapter that I’m trying to use on my 16.04 lts machine. The box for the tp-link states: Linux (kernel 2.6.18-4.4.6) However this means that you need to find a zipfile on the tp-link website wich contains code and instructions on how to “make” the driver and install it. And that’s where things went wrong. The instructions are straightforward:
$ make clean
$ sudo cp 8814au.ko /lib/modules/4.4.0-142-generic/kernel/drivers/net/wireless/
$ sudo depmod –a
output: modprobe: FATAL: Module 8814au.ko not found in directory /lib/modules/4.4.0-142-generic
I have then tried 3 different variants on this theme that I found on this site all with similar results. Last one I tried is this one: I'm Trying to install rtl8814au drivers fairly new to linux specifically these commands:
$ sudo apt-get update
$ sudo apt-get install git dkms
$ git clone https://github.com/sbosshardt/rtl8814AU.git
$ cd rtl8814AU
$ sudo ./dkms-install.sh
Alas no working wifi adapter but I now have this output from running the script:
sph@SKYBOL:~/Desktop/driver3/rtl8814AU$ sudo ./dkms-install.sh
About to run dkms install steps...

Running module version sanity check.
Error! Module version v4.3.21_17997.20160531 for 8814au.ko is not newer than what is already found in kernel 4.4.0-142-generic (v4.3.21_xxxx.20171031_beta).
You may override by specifying --force.
DKMS: install completed.
Finished running dkms install steps.
And when I do:
sph@SKYBOL:~$ dkms status
rtl8814AU, 4.3.21, 4.4.0-142-generic, x86_64: installed (WARNING! Diff between built and installed module!) virtualbox, 5.1.38, 4.4.0-142-generic, x86_64: installed
This looks like this problem: Install rtl8814AU driver on ubuntu 16.04
However I am not sure how to proceed.
Do I use –force like the error message suggests?
If so where do I use it?
Also I am not sure how “unclean” my system has become.
Are there any files left laying around from previous attempts that will interfere with new attempts at installing the right driver?
