Does it work in kernel 4.4.0-93? The modinfo looks correct

Right now the only wifi signal/icon visible in the wifi tray is for the laptop internal. Last week there were 2 choices, but now only one. So far the Realtek is not showing up in the wifi tray. (I have rebooted twice today already as well.) This same issue came up about 18 months ago after an upgrade to Cinnamon, and it had to do with using the Terminal to open up the USB port the Realtek uses, etc. Back then I had a local friend who was familiar with Linux who fixed it for me, but unfortunately he no longer lives close by.

See what happens with this

Code: Select all

sudo modprobe -r ath9k

Code: Select all

iwconfig; ifconfig

Code: Select all

iwlist scan

Code: Select all

lsmod | grep 88


I thought about this a little more. Is Secure Boot enabled in the BIOS? The 4.4.0-21 kernel that was the original kernel for LM18 did not enforce Secure Boot rules, everything later did and since the rtl8812au is compiled from source, it is unsigned and a kernel that enforces Secure Boot rules with Secure Boot enabled will refuse to load the module

Unfortunately I have no idea what you mean by any of this. I am willing to take directions and learn what I can, but this is all still very new to me.

I don't see anything that would indicate you have a UEFI install but the module isn't loaded either, try

Code: Select all

sudo modprobe -v 8812au

Your last comments about not finding the software made me remember that the aux antennae came with an install driver CD. The name is Netis. For the WF2561 AC1200 Wireless Dual Band High Power USB Adapter.

So it looks like I may have the missing software you need, but I will need some help mounting it if it doesn't auto install straight from the CD tray. Which is what I will attempt to do right now....

UPDATE: It did not self mount or auto install. This is the file name from the CD: rtl8812AU_linux_v4.2.5_10143.20140103_ASUS, which I have saved/extracted to the Desktop. See also attached pic.

Can you show me how to mount this?

The "Exec format error" is caused by a bug in the rtl8812au-dkms source code. Let's use code from github that work

Code: Select all

sudo apt-get purge rtl8812au-dkms

Reboot

Code: Select all

sudo apt-get install git

Code: Select all

git clone https://github.com/jeremyb31/rtl8812AU.git

Code: Select all

sudo dkms add ./rtl8812AU

Code: Select all

sudo dkms install 8812AU/5

Reboot and it should work

The driver on that disk is 3 years old and it isn't likely to work with a 4.4 kernel as the driver was made when the 3.13-3.17 kernels were made

The final command gave an error code:

Code: Select all

sudo dkms install 8812AU/5
Error! Could not find module source directory.
Directory: /usr/src/8812AU-5 does not exist.


All other commands worked OK I think.

I don't know if it (the final command) is supposed to look like that, so i will go ahead with the reboot and come back with an update....

UPDATE: No joy. Realtek still not loaded into the WIFI tray.

YES!!!!! Realtek wifi is back up and running!!!!! Thank you so much for your time and patience Jeremy, I couldn't have done it without your help!

One final request if I may. Now that we know what the total issue was, would you please make one last post with all the necessary commands all together one last time in correct order, in case I/we need them again after another major update next year or something? Many thanks in advance!

This should do it on a new install

Code: Select all

sudo apt-get install git dkms build-essential

Code: Select all

git clone https://github.com/jeremyb31/rtl8812AU.git

Code: Select all

sudo dkms add ./rtl8812AU

Code: Select all

sudo dkms install rtl8812AU/5

Then reboot

Perfect. Thanks again!

Now that the basic issue if connectivity is solved, I'm wondering if you have any insider tips or tricks on how to make my system more reliable? In other words, any tips on increasing bars while limiting drop out would be greatly appreciated.

I'm on a public router (not mine), so I don't think those tips are for me. Thanks anyway.
