rtl8812AU and/or rtl8814AU drivers

Likewise, a lot cannot be done because it does not work well.

BenSisko · September 23, 2020, 10:30pm

Yeah, I can't connect either with the patch he posted but it scans and this is the first patch I've seen using the aircrack source for openwrt. I know aircrack drivers work in client mode on arch linux so I think it's a step in the right direction at least.

It connect only to encrypted networks, some parameter seems to be missing that make it look on the web UI that is not connected.

Hi,

trying to compile the RTL8812AU driver but I cant find:

compat-wireless "Module.symvers" located in build_dir/target.../linux-.../compat-wireless into the folder "staging_dir/target.../usr/include/mac80211/Module.symvers" as to allow proper linking

I have copied the driver to the proper location and I can find it in make menuconfig

I am building OpenWrt 19.07.2 for x86 on Ubuntu 20...

I get this error:

How can I resolve this?

1715173329 · October 5, 2020, 7:34pm

I tried the driver above, and it works.

In my environment, it cannot run AC & AP mode (and reboot is required if switch from one to another) at the same time, and the LuCI seemed not right as some info may not provided correctly by driver or we cannot identify it.

Howerver, it's really a bit step supporting RTL firmwares, hoping it would be better in the future.

gimbleguy · January 20, 2021, 1:08pm

Thank you so much Jeff. Much appreciated for your work. This patch works really well with the latest snapshot of OpenWRT. I'm using the ALFA Awus1900 USB wifi.

Keep up the good work. Please let us know if you have any more new patches.

Thank you

gimbleguy · January 20, 2021, 1:14pm

Just doing some comparison with my WRT1900acs V2 running the latest OpenWRT snapshot. I have the ALFA Awus1900 USB wifi connect at the back of the WRT1900acs usb port.

This is a 5Ghz stock test no tweaking or tuning on the WRT1900 wifi and the ALFA wifi.

WRT1900acs V2 @ 5Ghz wifi

ALFA Awus1900 USB @ 5Ghz wifi

Check the pings!
Jeff's driver is a blessing in the skies. Thanks again Jeff!

gimbleguy · January 20, 2021, 11:29pm

I don't have Ubuntu, but I use MXLinux(debian freespin). It should be similar??

gimbleguy · January 22, 2021, 5:41am

Just awesome

Around 10 meters behind a plaster wall

Around 7 meters, behind 2 plaster walls and a large wardrobe and TV blocking the Awus1900.

All tests done on 5Ghz wifi Channel 161. Clients have intel 7260ac

Using Jeff1's patch.

For some reason none of the drivers in the Openwrt package lists work with this Awus1900. Only Jeff1''s patch. If anyone has managed to get one of the drivers in the OpenWRT to work with this Awus1900, please let me know.

Cheers

Hello I use edup 1612 8814au (3x3, 4 antennas) as an access point at an x86-64 home server running openwrt under proxmox

Jeffs patch works very good .
Gimbleguy thank you for the video how to compile
With openwrt the device has much stronger signal than both aircrack-ng driver under linux (hostapd) and windows 8.1 with realtek's own utility as an access point (at openwrt I can choose 30db with the right country i.e. panama)
Speeds are on par wih windows 8.1 access point and at difficult rooms better than windows (with 30db setting ).
Using as a client a dell1830 (3x3) card I can see about 560mbit/s (at the same room with 8814au)

but there are some problems:

the most serious is that I can not use a channel above 48 (5240). The channels 5260-5320 and 5500-5885 are shown at the luci drop-down list and I can choose them. Luci reports that it transmits at the chosen channel (i.e.5500) but it has switched to 5180 (36). Tried to change countries without much luck.
iw list shows that all the above channels are available
At debian hostapd says something about neighbouring BSSes and automatically changes channel (at some of the
mentioned channels)
At windows I can transmit at all the above channels as access point (so it is not a hardware thing)
After I change a hardware setting (i.e transmit channel) a reboot is needed. Without reboot the clients associate but the password is not accepted
The CPU usage seems much higher with openwrt than debian even without traffic (just with clients connected).
At linux I have about 2-3% of a single CPU (i5-6500) and at openwrt about 10-12%. I think it helps if I chose to install USB3
drivers at make menuconfig --> kernel modules --> USB support --> Support for USB3 controllers
With it enabled I think it idles at 5-10% (instead of 10-12%). I need to do some more tests for it
I need to install not luci but luci-ssl (else I have problems connecting with firefox)

Any help with the channel problem will be much appreciated

Thank you

pdionisis · February 28, 2021, 5:07am

Another problem.
When the power is cut and reboot the device is "disabled".
I need to manually restart the device from Luci in order to be enabled
This is a big problem because at a power outage the AP is not available.

Any solution?

pdionisis · March 6, 2021, 6:54am

I can not get a console with enter or ctrl-c after a power outage

Only way to get a console is to do a restart of wireless device through Luci or reboot manually openwrt (from luci no console)

Next is the screen after a reboot

It seems that 1st boot stops just before "usbcore: registered new interfaxe driver rtl88XXau"

For snapshot on x86, I made a video for you.

Giant thanks for your description. Now I'm able to compile with success. I was trying to compile stable version and it was my trap.

I have similar observations:

Client mode works only after reboot (any seting change need reboot);
In AP mode i can change channal in luci but in deed it is still 5180 (36); I can change bandwidth; Without reboot the clients associate but the password is not accepted;

So far no solutions.
