Arch Linux User Repository

This package now forces to use the branch v5.6.4.2 (the one that works better for me), which is the default one in the remote repository although they still mention branch v5.3.4 as the stable one. If you have any issues, please leave a comment, and also tried to change the branch in the source array. For example, change it to:

source=('rtl88xxau::git+https://github.com/aircrack-ng/rtl8812au.git#branch=v5.3.4'

Read the README.me to learn how to set your interface in monitor mode (and other things).

Important: Use ip and iw instead of ifconfig and iwconfig

If DKMS can't compile the driver for kernel 5.6 and 5.7, just install the package again on (top of itself). I was debugging my rig with cats and dogs, but installing the package updated it from r1038.945d6ed to r1059.8b29c11 which did the trick. (And as of writing this, the package version listed on the top of this page is r999.65174c4 to confuse me even more ;)

the workaround for iwd are no longer needed.

yshui's advice seem to have solved my long standing problem. :-)

For people who uses iwd and is experiencing problems with hangs after loading the module, you can try adding this to /etc/iwd/main.conf

@iyanmv, thanks for reply and yes indeed tricky. You inspired me to read some more and for anyone interested here are a few thoughts. I turns out its not more interfaces I should be looking for. Reading about IEEE 802.11ac at Wikipedia it seems like a adapter marked with AC1200 should be able to use 2.4+5GHz at the same time under the right circumstances. Reading about the rtl8812au chip on realtek homepage it seems the chip should be able to be used in 802.11ac/abgn or 802.11ac 2x2 combination. But how to configure it is a mystery and probably has more to do with how the AP is set-up. I'll see if I can find a good forum for hostapd and see if anyone there knows more.

Again, thanks and may the arch force be with you!

PS. I already have two USB adapters, one dedicated for 2.4 and one for 5 GHz APs, this is just because I'm curious and what to understand how stuff works. Now I'm also curious about aircracking so I'll dig more into that :)

@k96hkh this is a tricky question. To be honest, I do not know if this driver would work even in the case that your chipset supports that. But you can give it a try and figure it out. First, I would be sure that your device can simultaneously use both bands at the same time. iw list can help you find that out. Having two antennas doesn't mean that it can use both bands at the same time. Normally you can create as many software monitor interfaces as you want (iw dev YOUR_CHIPSET interface add NAME_MONITOR_INTERFACE type monitor), although with this driver I have issues with this thing, but they will compete for the resources, meaning that if you, for example use airodump-ng simultaneously with both interfaces on different channels, it will not work as you expected. There are some chipsets that support that though, but I guess you will have some lines in the "interface combinations" section when you run iw list.

What I usually do when I want to scan both 2.4 and 5 GHz bands is select the specific channels and let airodump-ng hop from one to another. It works quite good. For example, airodump-ng -WMU wlp0s20u1 -c 1,6,11,36,44

Thanks for a great work on this package! I have a question and maybe someone here knows or can point in the right direction. I have an USB external adapter with two antennas. Is it possible to create one AP at 2.4 GHz and and one at 5 GHz at the same time? What I have found on the internet is: Maybe if two interfaces are created for the adapter. Is this something rtl88xxau driver can do? Is it depending on adapter or maybe just "no can do".

Cheers!

@banzr not really, what if someone uses linux-lts, linux-hardened or linux-zen? Why would they want linux-headers on their system? I think people using dkms should take care of installing the headers they need. All these are mentioned as optional dependencies when installing dkms.

This package is missing a dependency to linux-headers.

Versions of this driver after r918.73f0a88 still completely knocks out my system as described below. https://aur.archlinux.org/packages/rtl88xxau-aircrack-dkms-git/#comment-716905 r918.73f0a88 still works fine.
