I liked this one the best, it is specific for 8821au and is packaged on AUR. While driver #3 eventually worked for me, I would certainly recommend trying the other ones also, it is very likely they might be working for you when you try this. The problem is, it takes some time for drivers to catch up with new kernels, and some of them get stale, so you might need to try out a few of them in order to find one that works. create file /etc/modules_load.d/nf with just one line: 8812au, if that is the name of installed driver.).įinally, if driver is set up correctly, when we plug in the wifi adapter, we should see new entry for it when we run ip link. Make sure driver module loads on system boot (e.g.Make sure we have dmks installed (dkms ensure that driver is rebuilt when kernel is updated).Regardless of which driver we choose, installing/setup should go something like this: There are even more drivers, but these ones seemed most prominent to me at the moment of writing. rtl8812au (Github, gnab) -> also just github, also has decent number of stars.rtl8812au (Github, gordboy) -> this one is just github, no package, has decent number of stars.rtl88xxau-aircrack-dkms-git (AUR) as alternative choice since it is more general.rtl8812au-dkms-git (AUR) as reasonable first choice.Btw, you can also check first if dongle is shown via lsusb, that should work even without driver, if not then there is some other problem also involved.Īlfa AWUS036ACH uses Realtek 8812au chipset so we need driver for that chipset. Run ip link to see if your dongle is recognized (is there new entry when you connect it to your PC?). Still, it took some effort to set everything up as I wanted, so I will describe the steps here. I found on the net that others got Alfa AWUS036ACH working on Arch so I went with it! Therefore I decided to buy wifi dongle, and was looking for one that can work with Arch Linux. My laptop does not have the best network card: it works only with 2.4GHz networks and it has poor signal. Setting up wifi dongle (Alfa AWUS036ACH) on Arch Linux.
