rtl8812AU and/or rtl8814AU drivers

For Developers
145

Hi I'm no programmer too just a hack.
Unfortunately, I haven't build for 8814au in a while since I switch to a dedicated AP and I tried to build a few times before I post this and no luck.
The makefile is basically derived from openwrt/package/kernel/rtl8812au-ct/Makefile
I'll post mine anyway, you might find something useful.

Depends on your target platform, I also had to make changes to the src Makefile to get something compiling. Last time I was able to build the module I think I had to remove -Werror in OpenWrt just to build the module, but can't remember were exactly.
This is as far as I was able to build untill I got an error:

I will try to keep building and see how far I can go.
BTW I build from git master.

146

yes, I also got werror warnings. what I found was if you delete the

NOSTDINC_FLAGS = \
        -I$(PKG_BUILD_DIR) \
        -I$(PKG_BUILD_DIR)/include \
        -I$(STAGING_DIR)/usr/include/mac80211-backport \
        -I$(STAGING_DIR)/usr/include/mac80211-backport/uapi \
        -I$(STAGING_DIR)/usr/include/mac80211 \
        -I$(STAGING_DIR)/usr/include/mac80211/uapi \
        -include backport/backport.h

the compile will be success. but the module won't work.

I will post my Makefile and patches later

Drivers for RTL8812AU are included in OpenWrt 19.07.

You might want to check it here:

Hi all

Is there any particular hint to make it to work?

I am using a rtl8812au dongle on Raspberri PI4 on snapshot

The dongle is recognized but the first strange thing comes from the configuration page, where in 5Ghz there is no possibility to change between AC and N mode.

But trying to bring up and access point in 5Ghz oe 2.4Ghz return hostpad errors and after a while the drivers is uninit

Bye

150

Try building the driver from this source:https://github.com/aircrack-ng/rtl8812au/pull/619
I had tested with rtl8811, rtl8812au and rtl8814au USB WiFi dongles, working well and has AC mode support.

151

How could I test that driver?

152

You have to download the source driver and cross compile or add it to OpenWrt Buildroot as a patch https://github.com/1Jeff1/openwrt/commit/5249b47cc4658ee78cb2a94362d3401cea90e9cd.patch

Should I download the patch? In which directory?

154

From the root directory:

wget https://github.com/1Jeff1/openwrt/commit/5249b47cc4658ee78cb2a94362d3401cea90e9cd.patch

patch -p 1 -i 5249b47cc4658ee78cb2a94362d3401cea90e9cd.patch

Do they work as APs?
A drawback to Realtek was they didn't (same with Intel)... I think.

156

@jeff1 Are you able to give a look at the 8812BU driver and try to build it in Openwrt?
I tried but with no success, I have limited knowledge of Openwrt build system

157

BTW tried the driver built in the latest snapshot
Actually it is working as bad as the -ct one currently in the repo
I am not able to run it in AC mode, sometimes it works in N mode @2.4Ghz, but slow and for example there is no rate indication

158

I want to try this driver on the nanopi r2s, but I get this error when is compiling:

I updated the rtl8812au-ac driver, It should work now.

Thanks @jeff1 I was able to compile the WiFi driver for the NanoPi R2S and confirm working with my dongle Alfa AWUS036ACS with no issues at all, also this driver works better than the one used on friendlywrt as this support AC WiFi.

161

How did you set it up? By CLI or GUI?

162

I set it up using GUI, I'm not familiarized with CLI.

163

I mean by LuCI? Because I have an Archer T4UHP with the rtl8812au chipset and it doesn't work.

164

@jeff1
I managed to compile your rtl8812au-ac driver package as single package for 19.07.3 on a Archer C2600 (have modified 0003-wireless-5.8.patch to match the older kernel code). The driver can do a successful scan on my ASUS USB-AC56 wifi device (after having problems with the delivered rtl8812au-ct driver).

The problem is, that I am not able to successfully connect to a hotspot:

Any idea why the wifi disconnects directly? The same config works on a other device.

Thanks for creating this patch and for using the aircrack driver! I am able to scan!
Haven't previously been able to do that.
