Arch Linux User Repository

To all having an issue with this driver: please try https://aur.archlinux.org/packages/rtl88xxau-aircrack-dkms-git alternatively.

How goes the investigations? Are driver version 5.2.20.2 more stable? (I have recurring connection issues with the present version.)

@lupoalberto

What works?

Your chipset is not suitable for THIS driver, and that is all I actually care about.

If you can find another driver that actually FULLY supports your chipset, then fine. But I don't think anyone here in this particular space cares very much. The comments here are for the RTL8812AU driver alone, but thanks for your input.

@gordboy, thanks for comment but although my adapter is based on RTL8812BU chip it works. Don't as I want but works.

Look there https://aur.archlinux.org/packages/rtl8822bu-dkms-git/

@lupoalberto

Sorry my friend.

Your device is RTL8812BU and therefore this driver will not work with it, as the driver only supports RTL8812AU and no other.

In fact, I don't think there is a Linux driver available yet for your device.

The Windows 10 driver works but no Linux driver, as far as I know.

@zebulon, I've such Dual Band USB Adapter named as AC1200M. When I insert it in usb port I get this:

~/ lsusb | grep Realtek

I'm trying do

sudo modprobe 8812au

and get

~/ lsmod | grep 8812au

but the adapter dosn't work (ifconfig does'n see it).

Could you help me to make it work?

@gordboy: sounds fantastic, thank you. Will do the update later this week once we have a chance to do further testing. But great, thanks!

@zebulon

I've updated my main repo to driver version 5.2.20.2, which has a massive rewrite of phydm making the driver much more stable (thus far).

I tested for our old friend the "4 second glitch" and it seems to have been greatly reduced or removed entirely. If I do

ping 192.168.0.1

from my laptop (to the router), instead of getting the usual occasional 4000ms ping time, the maximum is now 300ms. Anyways, fingers crossed, splice the mainbrace, and Tally Ho! this seems to be a very worthwhile update.

Of course, if it all breaks tomorrow, I will go back to 5.2.20 ... :)

I had those. The problem was solved by rebooting the AP. So it had nothing to do with the driver. Sorry for the noise!

@mokkurkalve driver works fine with 4.17.2 and also 4.18-rc1.

Please make sure you have

[device]
wifi.scan-rand-mac-address=no

in /etc/NetworkManager/NetworkManager.conf.

Also make sure you have the correct regdb files in /lib/firmware, as mentioned in the notes.

@mokkurkalve: thanks for reporting. I am away from my computer for a while, so unable to test. But once this is confirmed and fixed, I will make the package available as soon as possible.
