[SOLVED] Odroid C2 Wifi? RTL8811au

[danderson198]

Have usb wifi adapter netgear ac600 chipset rtl8811au will not work. Android 5.1.1 ver 2.1. Says you have rtl8811au drivers in kernel but wont work?

[odroid]

We've tested/supported only below wifi chipsets on Android OS.
Wifi module 5: Realtek RTL8812AU(0BDA:8812)
Wifi module 4: Ralink RT5572 (148F:5572)
Wifi module 3: Realtek RTL8188CUS (0BDA:8176)
Wifi module 1/0: Ralink RT5370 (148F:5370)1

Try to edit /etc/wifi_list.txt file to add the VID/PID of your chipset.
But I am not sure whether it works or not.

[danderson198]

Thanks for the reply!

VID/PID is 0846:9052

This is what I added to the wifi_id_list.txt
/* Netgear - Edimax */0846 9052 8812au /system/etc/modprobe.d/8812au

Not sure if this is right but it didnt work.

Device has rtl8811au chipset but should work with 8812au driver? IDK?

[danderson198]

Update!
Did a fresh install and updated to 5.1.1 ver 2.4 and added this to the wifi_id_list.txt

0846 9052 8812au /system/etc/modprobe.d/8812au

Used this entry instead of the one I tried earlier. Used Solid Explorer File Manager to edit and save text file.
Rebooted and it now works!

rtl8811au chipset works with 8812au driver.

[odroid]

Good to hear we have another working WiFi chipset.
Thank you for the confirmation.

Could someone show me step by step on how to edit the Odroid C2 Wifi RTL8811au driver? I don't know where to go or how to edit the /etc/wifi_list.txt file to add the VID/PID of my chipset. And also where could I find the VID/PID of my chipset.

This is how I did it...

You can get your device VID:PID by unplugging your wifi adapter and typing "lsusb" without the quotes into the terminal emulator then plugging your wifi adapter back in and typing "lsusb" again and taking note of the new device that shows up.

To edit the wifi_id_list.txt I downloaded and used solid explorer file manager app. I used this app because the regular file manager app wouldn't let me save the edited text file for some reason even with SU privileges.
Once you download and install the app click on the 3 bars icon in the upper left corner of the app and click on the root folder then click on the etc folder and scroll down. The wifi_id_liist text file should be towards the bottom. click on it and scroll to the bottom then add this...

0846 9052 8812au /system/etc/modprobe.d/8812au

But make sure to change the VID:PID "0846 9052" to match your device. Then click on the save icon in the top right corner of the app. It might not save it the first time so just click on the red circle with a X in the upper right corner and click save again and it should say file saved. Then reboot and should work if your device has the rtl8811au chipset. But keyword here is "should." Not 100% positive it will work but it did for me.

[Mista Dista]

Cool. Thanks for the info. I'll let you know if I could also successfully edit my driver as well (RTL8811au)

[jspeed3]

is there a way to do this in linux

[danderson198]

is there a way to do this in linux

In general not exactly sure. I think linux comes with the 8812au driver if you were refering to that specific driver.
I plugged the listed wifi adapter in using linux and it worked no problem.

[Wladyslaw]

Unfortunately, this method did not work for me.

Device: TP-Link Archer T2U Nano
Chipset: Realtek 8811AU
VID:PID 2357:011e

Added the device to the list echo "2357 011e 8812au /system/etc/modprobe.d/8812au" >> /system/etc/wifi_id_list.txt and rebooted. But the kernel module was not loaded.

Android 6.0.1 ver. 5.6
dmesg | grep RTL:

Code: Select all

[  203.376977@3] RTL871X: module init start

[  244.481907@0] RTL871X: module exit success

Looks like an issue with the particular (old) version of the driver, newer versions (like https://github.com/jeremyb31/rtl8812au-1) should support it, see https://askubuntu.com/questions/1149117 ... untu-18-04

Any help?

[odroid]

We will check whether a newer RTL driver can be ported to the old Android kernel 3.14 or not.
It may take a couple of weeks.

[Wladyslaw]

Compiled driver v5.6.4.2 for x86_64 kernel 4.4.0 - works fine (2.4 and 5GHz). There is also a config for S905, but it has a different structure than yours, could not figure out yet how to merge it.
NB, TP-Link devices are included in your version of usb_intf.c as well, but it just does not start...

[odroid]

We've tried to port this new open source driver to C2 Android Kernel, but failed because we met some compiling errors with the old C2 3.14 kernel while the C4/N2 Kernel 4.9 could successfully merge it. Sorry about that.
https://github.com/aircrack-ng/rtl8812au/tree/v5.3.4

[Wladyslaw]

Yes, I also tried native compile with gcc-4.9 against the 3.14 kernel sources, but getting errors.

[Wladyslaw]

Managed to fix some errors and ignore others, compiled version v5.6.4.2_35491.20191025 (from https://github.com/aircrack-ng/rtl8812au) for Ubuntu kernel 3.16.82-59. Driver works. Writing this message from C2.

• module is loaded automatically (I must have not run the depmod correctly)

• module is linked as 88XXau.ko and should cover both 8811/8812au, 8821au and 8814au chipsets

• device is displayed correctly as single dual-band interface (I must have compiled it with CONFIG_CONCURRENT_MODE earlier)

• module also works with dkms (automatically recompiled with kernel upgrade to 3.16.85-62)

But, although I was able to compile it against the Android 3.14 kernel (there were just a couple of warnings to fix), the Android module still does not work for me.

[Wladyslaw]

Still struggling with the Android driver.
Compiled with minor fixes and 8814a=n, replaced the module in /system/lib/modules.
After reboot, the cfg80211 and mac80211 modules are loaded, but 8812au not.
Inserted the 8812au.ko manually, ip link shows wlan0 and wlan1 (still don't understand why there are two, but it says in the Makefile that it is required for Android).
Could make wlan0 up with ip (device LED starts blinking), but not wlan1. But Settings app does not see them. Cannot test with iw, as there is no iw on Android.
What else should I try?

[Wladyslaw]

Finally got it working!
(Yes, writing this from Android )
Driver compiles with make KSRC=../linux ARCH=arm64 CROSS_COMPILE= KVER=3.14 -j4 and runs. (I guess, just need to chmod 644 8812au.ko)

Great!
We will try your patch in the next week.

[codewalker]

I applied your patch and modified some codes.

Test version is here.
https://dn.odroid.com/S905/Android/test/marshmallow/

I will test this driver for a few days.

Thank you.
