WIFI driver help please :)

[thomas110]

Hello. I am running the latest version of Ubuntu in VMware Workstation 12. I have a USB wifi card that operates on the RTL8821AU chipset. I have the driver (I think) but when I go into the terminal, and navigate to the driver directory, I put in this command "sudo make install" and I get "No rule to make target 'install'. Stop" I also get this when I try to do the "load" or "unload" command with sudo. I am new to Ubuntu and I would appreciate some help please. Please help me with a step by step guide in as much detail as you can. Thank you all so much. If you need any other information from me, please just advise :)

[jeremy31]

Where did you get the driver from? Have you installed build-essential and linux-headers-generic?

[thomas110]

I have not installed build-essential and linux-headers-generic, and I got the driver from: https://github.com/ulli-kroll/rtl8821au

[thomas110]

UPDATE: Okay. I installed the 2 packages above and here is what I got from the terminal: https://thomaskal.gyazo.com/043da20f957adc7baf1c1ba6d71764df

[jeremy31]

The terminal says to run
apt-get -f install to fix the problems and it may install another driver that should work

[thomas110]

It installed, then I rebooted but the wifi still is not showing up in the top right, Thanks for your help though :) https://thomaskal.gyazo.com/ebec3259270b16752f0bec5a7bc051c3

[jeremy31]

See the wireless script link in my signature and post your results

[thomas110]

Okay. It will be a few mins. It is taking a while to update

[thomas110]

Here it is: http://pastebin.com/4wG7FgXj

[jeremy31]

What happens if you
sudo modprobe -v rtl8821au

[thomas110]

FATAL: Module rtl8821au not found in directory /lib/modules/4.4.0-22-generic

[jeremy31]

How about
sudo modprobe -v rtl8812au

[thomas110]

Still: modprobe: FATAL: Module rtl8812au not found in directory /lib/modules/4.4.0-22-generic

[jeremy31]

Is secure boot enabled? If it is the module will not be allowed to load. I just built the rtl8812au-dkms on my computer and loaded it

[614657.287926] 8812au: module verification failed: signature and/or required key missing - tainting kernel
[614657.291653] RTL871X: module init start

You may have to try
sudo modprobe -v 8812au

[thomas110]

So how would I disable secureboot on Vmware if you know?

[jeremy31]

This might do the trick for vmware install

sudo apt install mokutil
sudo mokutil --disable-validation

This was found at http://askubuntu.com/a/762255/300665

[thomas110]

The second command yields: EFI variables are not supported on this system

[jeremy31]

Is there any response from
sudo modprobe -v 8812au

Might as well add results for
dkms status

[thomas110]

For sudo modprobe -v 8812au, when i hit enter it just goes to the next line. No error.

Fir dkms status gives me some hope: rtl8812au, 4.3.8.12175.20140902+dfsg, 4.4.0-22-generic, x86_64: installed

[thomas110]

But still nothing comes up in iwconfig or ifconfig for wlan0 or anything like that.

[jeremy31]

For iwconfig, you will likely not see any wlan with the new naming, it might be wlx??????????? any result from
dmesg | grep 8812

[thomas110]

Okay. So. I tracked down the 1st party driver from Realtek and here it is along with all the documentation for Linux: https://www.dropbox.com/s/es6h2pyd0e75xe4/linux.zip?dl=0 (UPDATED LINK)

[thomas110]

No result from dmesg | grep 8812Just goes to the next line

[jeremy31]

Does the wifi work in the host? It may have to be disconnected from the host to be used in the guest. The module installed works on normal installs. I am downloading a new ISO to try on vmware to see if my USB wireless card works

[thomas110]

Thank you. Yes It works on the host, but it is connected to the VM. It even shows up in Ubuntus USB list. Another thing I noticed when I "cd" into the driver folder, I try to run the command "sudo make install" to install the driver, but I get this error: install: cannot stat '8821au.ko': No such file or directory

[thomas110]

And that is the driver that came with the usb adapter for Linux. Sudo make load or unload brings up "no rule to make target 'load'. Stop" also. Is it something wrong with the VM or the driver you think?

[jeremy31]

sudo apt-get remove rtl8812au-dkms
That driver was missing the alias for your wifi

git clone https://github.com/ulli-kroll/rtl8821au.git
Ignore if it says something about a non-empty directory, already exists

cd rtl8821au
make
sudo make install
Then restart the guest

[thomas110]

The very last command "sudo make install" I get "make: *** No rule to make target 'install'. Stop."

But everything ellse works fine

[thomas110]

is this an error with the Makefile?

[jeremy31]

It is not a normal makefile for some reason, lets try a different way

sudo cp rtl8821au.ko /lib/modules/$(uname -r)/kernel/drivers/net/wireless
sudo depmod -a

Restart guest

[thomas110]

cp: cannot stat 'rtl8821au.ko': No such file or directory

For the first command

[jeremy31]

Probably weren't in the correct directory

cd rtl8821au
sudo cp rtl8821au.ko /lib/modules/$(uname -r)/kernel/drivers/net/wireless
sudo depmod -a

Then restart guest

[thomas110]

Done. It just skips to the next line. The command goes through but still no wifi

[thomas110]

The first way we tried it: cd rtl8821aumake
sudo make install

That worked up untill the last command when it gave me the error. I read that it could be the Makefile. But it was so close.

[jeremy31]

Post
lsmod | grep 8821

The makefile doesn't contain the normal install header so it won't work

[jeremy31]

Run the wireless script again, the module is loaded

[thomas110]

ok

[thomas110]

[jeremy31]

Try
systemctl restart NetworkManager.service
It shows it being renamed to enx from wlan0, so it could be the network manager bug

[thomas110]

You legend.

[thomas110]

It worked. Thank you so much.

[thomas110]

So now, when I restarted. Its gone again!!!

[jeremy31]

If it works, use the thread tools to mark as solved, I hope that bug is fixed soon

A note to anyone who may come across this thread from a search, please use https://github.com/abperiasamy/rtl8812AU_8821AU_linux

sudo apt-get install git dkms build-essential linux-headers-generic
git clone https://github.com/abperiasamy/rtl8812AU_8821AU_linux.git
sudo dkms add ./rtl8812AU_8821AU_linux
sudo dkms build -m 8812au -v 1.0
sudo dkms install -m 8812au -v 1.0

[thomas110]

Good news: It has detected the wifi adapter and I can see my networks, but I can barely connect to them. And the connection is very slow

[thomas110]

Thank you very much again for your help. I couldnt have done it without you :)

[jeremy31]

It may be worth trying the alternative I posted, I know chili555 has posted answers using it.

Gone after a restart, did you not have this set as persistant

[thomas110]

I did. For some reason I have to unplug and re-plug the adapter in then it detects it, and I am able to connect to a network but load minimal things. Almost like the adapter is running at like 5% power
