Alfa AWUS036ACH (AC1200) not working [Solved]

Post by Mumrik93 » Mon Jul 29, 2019 8:01 am

Hello!

So i've just migrated over to Linux and noticed that my former wifi adapter (Netgear a2610) did not work as great on Linux as it had on Windows, as such i set out to find an adapter that did work better and linux and the Alfa AWUS036ACH adapter was recommended to me. I've just got it, plugged it in, the driver manager detected it so i used my phones shared internet to download it, rebooted.. and then nothing. The adapter still does not light up nor does it connect to the router, the Network manager does not even detect it, but the driver-manager still does and claims the drivers are installed and fully functional.

So i've hit a bit of a wall now, i've been looking around and i cant find out what the problem is, not do i find any who might have the same problem i could discuss with. Does anyone here happen to know what the problem might be? And how it can be solved?

The screenshot below shows the driver-manager and the driver for the wifi-adapter being installed and ready to use.

Should mention that i did try to run one of the possible solutions found here;
viewtopic.php?f=53&t=294630&p=1638313&h ... H#p1638313

I ran the commands (lsusb) and indeed the wireless adapter was found, but when i tried running the commands to "Activate" them (modprobe 8812au) the only answer i got was this;
modprobe: FATAL: Module 8812au not found in directory /lib/modules/5.0.0-20-generic

Please generate an overview of your system like this:
- Launch a terminal window (this is how to launch a terminal window);
- make the terminal window full screen, to avoid chopped lines;
- Copy/paste this command into the terminal:

Code: Select all

inxi -Fxz
(if you type: the letter F is a capital letter)

Press Enter.

Copy/paste the output in your next message.

Do the same with the following four commands:

Code: Select all

rfkill list all

Code: Select all

iwconfig

Code: Select all

lsusb

Code: Select all

lspci

Done and done!

Good to hear! :)
You needed a better driver. Which you've installed now.

Note that (as the how-to says at the end) installing kernel updates will probably break the driver, so you might want to freeze the kernel as described in the how-to as well.

I had the same issues with my Alfa Network AC1200 adapter. The tips by Pjotr were right on and now it is working fine.

Thanks so much..
