Hi, trying to compile with included dkms-install script make “time and date” error while running make.

Sorry if is trivial issue to fix for savvy user, but might be good to know if unaware.

What I did was remove IF statement that check for version and make EXTRA_CFLAGS += -Wno-date-time always on. This was near line 23 of included Make file.

I have to remove the existing folder /usr/src/88x2bu- and run the script once more after apply change to Make file.

The driver has successful compiled on my old desktop with Kali. Monitor mode work now. Hope this help.

Unknow Hiro USB adapter, also. Want to say thank you for this version. It is not easy to find, I am glad it is here.

wpa_supplicant version is 2.8-devel by default along with latest raspberry pi OS.
Not sure if this is a known issue or not.

WPA3-SAE (Personal) is listed as part of features though it's not mentioned in client mode... need some help and clarity here.

BTW, gave it a try on macOS driver provided by Dlink https://support.dlink.com/ProductInfo.aspx?m=DWA-181-US on my macbook and both my Dlink DWA-181 and TPlink T3U were able to connect the same WPA3 AP.

There are some cases when it makes sense to disable Power Saving and there have been cases reported over the years where disabling Power Saving made adapters usable. I have no problems and only had one report of someone having a problem with this driver on a modern OS but I am inclined to add the options to turn power save off. I have added what I think are the correct module parameters to 88x2bu.conf but have not changed the README pending some testing and feedback.

Your testing and feedback is requested.

Nick

Can report successfully building and running the current driver on the following Raspberry Pi/OS versions:

Raspberry Pi 4B (armv8) - DietPi 64-bit, PiOS 32-bit

Raspberry Pi 3B (armv8) - DietPi 32-bit, DietPi 64-bit

Raspberry Pi 2B (armv7) - PiOS 32-bit

Raspberry Pi A+ (armv6) - PiOS 32-bit

• Swapfile increased to 512MB for compilation.
• Compilation time circa 4 hrs!

Also have a Pi Zero - but will get to that when time permits and update this post accordingly.

Can also state that AP mode, packet injection and USB3.0 mode work as expected on a Pi 4B running 32-bit PiOS.

Is there an AUR package?

I have another pi with an older driver working fine as a network bridge, when I install this driver and use the same bridge and iptable configs it does not pass traffic through the vpn.
Raspberry Pi mod 4, Raspian OS,
iptable config:
-A FORWARD -i eth0 -o wlan1 -m state --state RELATED,ESTABLISHED -j ACCEPT
-A FORWARD -i wlan1 -o eth0 -j ACCEPT
-A FORWARD -i eth0 -o tun0 -m state --state RELATED,ESTABLISHED -j ACCEPT
-A FORWARD -i tun0 -o eth0 -j ACCEPT
-A FORWARD -i eth0 -o wlan0 -m state --state RELATED,ESTABLISHED -j ACCEPT
-A FORWARD -i wlan0 -o eth0 -j ACCEPT
-t nat:
-A POSTROUTING -o tun0 -j MASQUERADE.
I would like to use your driver as when installed, and vpn is unloaded, it provides much better speed than the old driver.
Not sure what other info you might need, just ask and i'll provide.

Thanks in advance,
Gene.

Hi, thanks for your time in creating this driver =)

I'm running Mint 20 Cinnamon (4.6.7) Kernel 5.4.0-58-generic.
I've got a Comfast CF-812AC (Chipset RTL8812BU)
I've followed your instructions and when i go to the network icon I can see "realtek 802.11ac NIC" and AP's but I get a connection failed error when I try to connect it keeps saying Auhentication required and it won't connect.

There is another wifi adapter installed on this computer (will move the hard drive into another computer that doesn't have onboard wifi). When I disconnect the Qualcomm Atheros wifi adapter (see screenshot) it will also disable the "USB Wi-Fi"

Any idea how to get this working ?

Hi! Thank you for your work! On my machine I run Arch Linux with two kernel packages, the latest linux and linux-lts. I would like to use this driver for my Archer T3U on both kernels, but I noticed that the install script created a directory named after the driver name and its version, so when I compiled it agains the linux-lts headers it worked flawlessly and the driver was added to the dkms tree successfully, but when I did the same agains the linux headers, dkms found there already was the driver directory, so it stopped. Please, can you add support for multiple kernels? Do you think it's feasible by just adding to the dkms directory name the kernel version?

Hi,
I am doing one university project about mac address randomization, and I want to change the mac address during the probe request phase only to locally administrated, I tried in function _issue_probereq() function, the driver sends probe request with a new random mac just one and then don't move on to the authentication phase. I tried
u8 mac[] = {0xbe, 0xf5, 0x70, 0x99, 0x59, 0x1b} then
_rtw_memcpy(pwlanhdr->addr2, mac, ETH_ALEN)

To have 867Mb/s enable, the driver flag rtw_vht_enable_ should be set to 2.

Hi, I am using this driver to create an AP with WPS mode. I have populated the metadata fields and hostapd seems to believe that the beacon is being created properly. When I do an iw scan on a different pi I am picking up other devices wps data, but not that of this given AP. Ideally I would be able to get the Model Number, Serial Number, Device Type, and Device Name properly populated. On a different note that I haven't tried to investigating any insights into station count and utilization outside of WPS would be great as well. Example scan is here iw-scan.txt.

Can you list an explicit license on this repo? I'm working on packaging this for nixpkgs and would like to ensure that I can mark the right license for the module.

Thanks!

I did the installation, reboot and still not working.

Some outputs that might be useful:

I purchased a WiFi USB dongle which the seller claims uses the RTL8812BU chipset - https://www.amazon.com/gp/product/B08BYBL2TQ/ .

It shows up using lsusb as: Bus 001 Device 016: ID 0bda:b812 Realtek Semiconductor Corp.

) #5218.04.1-Ubuntu

Since the driver is not loaded, it does not show up for iwconfig or ifconfig.

I followed the install instructions and rebooted. When plugging the device in, numerous errors and warnings are added to the syslog, please see attached.

Could be an issue with the backport-iwlwifi package ...

Hello. I have ubuntu 20.04 and after reboot my TP-link t4u not connecting to the network with authentication error. I have to delete the network settings (forget the network) and reconnect with the password.

Hi, there is an error when i run sudo ./install_driver.sh.

Anyone help me pleeeeee..

I don't know how to send the author a note so I am posting here.
I have an AC1200 and it is working like GANGBUSTERS thanks to your git for 88x2bu
862mb/s (5Ghz) -- 👍

Looking into a kernel hang issue that seems to be happening with a 8822bu chipset wifi module that we are working with on a custom board.

This is running on a Raspberry Pi CM4 with a 64 bit Centos 8 Stream OS variant which is fairly bare bones. We are also running an 8812au chipset variant with your other driver. We can call iw dev wlan8812au del without any issues, but upon running the same command on the interface for the 8822bu, the kernel seems to hang. I have moved to various versions of iw and all paths lead back to a driver issue. I have been having hard time getting any sort of logs off of the device as after execution the entire device hangs and a hard power off and reboot is required. It seems none of the logs are surviving the reboot and am looking for any recommendations on how to debug and rule the driver out or rule the driver in. It seems this does not cause a core dump itself and have not seen a kernel panic other then a process is stuck.

Hey, I've tried using this driver with my Customer WU1300S and haven't been able to get it work in a proper manner

• Can't connect to 5GHz (despite them appearing), only 2.4GHz connections. 5GHz connections ask me to re-input password endlessly
• Connection speed on 2.4GHz connection is incredibly slow and inconsistent (below 1 megabit per second according to Google's speed test)
• Disconnecting the adapted and putting it in a different USB port might stop it from being detected at all

I'm on Linux Mint 20 with kernel 5.8.0-33 generic. The ID in lsusb is just 0bda:b812

I tried also using the driver listed on Cudy's website but I am having the same issues with that driver too, so I'm not certain this is an issue with this driver or if it's something related to my machine causing this. I did use a different wifi adapted previously and that worked fine, though (with in-kernel drivers). Any help would be greatly appreciated.

Sometimes I can't connect to AP with following message:

This happens when the signal is weak, when this happens if I move the client to a better signal location it wouldn't recover, However With a system reboot the problem goes away, and I can connect it again.

I've been trying to get this driver up and running on my raspberry pi 4 for the last couple of hours but no luck so far. The raspberry pi is running Kali 2020.1 with the latest upgrades etc. Installing the driver seems to work just fine and no errors occur.

However, I can't seem the interface up, I've tried "ifconfig wlan0 up" and "ip link set wlan0 up", both times I get the error "SIOCSIFFLAGS: Operation not permitted" (yes I'm running it as root so sudo isn't needed).

Kernel version = 4.19.118-Re4son-v8l+

I've been checking my logs but can't find anything related to the issue.

Hope someone can assist me in this matter.

Apologies if I am asking too much. My bodgy half-half ubuntu 20.10/Pop_OS! install seems to not want to play nicely with my new wifi dongle, and your drivers have gotten me the furthest so far over a few days of mucking about and swapping wifi dongles over to get onto the internet using my old slow dongle that works, searching up solutions, switching over to the new dongle, reboot, still not working, repeat.

Serial number is 123456 so I am pretty sure it's a dodgy knock-off of some sort?

Your install works well (much better than the dodgy files included in the url in the amazon listing) and actually goes through cleanly. I can see the driver loaded in lsmod

$ lsmod | grep 88x

I've followed the wifi setup hints (set my AP to split 2.4 and 5ghz into different SSIDs, set the channels and widths as recommended). But I am variously getting NetworkManager asking for the password over and over again, or spinning circle endlessly, or a "failed to activate network device" error.

I did get a solid connection briefly before I split my 2.4 and 5ghz wifi, but it was slow and DNS intermittently resolving. Lasted all of 20 seconds or so.

Thanks for help

I think the ARCH definition for CONFIG_PLATFORM_ARM_RPI should be:

ARCH ?= arm

The definition for CONFIG_PLATFORM_ARM64_RPI is correct.

We have kind of an odd set up and are using this driver.

We have two Cudy AC1300 devices with the rtl8822bu plugged into a Raspberry Pi 4 64 bit Centos flavored linux and using NetworkManager. One Cudy is connecting to a network and the other is in AP mode. Modified config to set USB to 3.0 and vht auto enabled 2. Seems that we are getting quite a bit of different behavior with two plugged in compared to just one. The first being kernel panics (logs pasted below). I've disabled the USB 3.0 and the kernel panic goes away. In USB 2.0 mode nmcli says that the AP is being broadcasted, but it is not until we physically unplug/replug the dongle. Both odd issues that I wanted to bring to your attention. If any other information is needed feel free to reach out.

Dear morrownr,

First of all, thank you very much! Your repository has made life a little bit easier, at least for me, since i've stumbled upon it. I've been using your driver for the Realtek-rtl8812bu chipset on a machine with both Linux Mint (Ubuntu based) and LMDE 4 (Debian based) very successfully 👍
(here the wifi adapter: https://www.amazon.de/EasyULT-1200Mbps-802-11ac-Dualband-Empf%C3%A4nger/dp/B07YDHTHH3/ref=cm_cr_arp_d_product_top?ie=UTF8).
Both USB 2.0 and USB 3.1 (gen1) were working fine. 👍

Here is the the problem:

When i use Fedora 33 on this same machine without GUI it doesn't work for me (i am trying to turn this machine into a server, but i am rather new to Linux). I am at a loss on how to activate the wifi adapter.

What i did to install the driver:

sudo dnf update
sudo dnf install -y dkms git
mkdir src
cd ~/src
git clone https://github.com/morrownr/88x2bu.git
cd ~/src/88x2bu
sudo ./install-driver.sh
sudo reboot

after the reboot i tried to check for wifi signals with:
(following this guide: https://ostechnix.com/connect-and-disconnect-wifi-from-commandline-in-linux/)

$ nmcli device wifi list

It doesn't give me any output though. No wifi networks are listed that i could connect to. See here:

Also the wifi-stick doesn't blink blue, so i think it still is turned off.

How to turn it on? Is the driver not compatible with Fedora or am i missing something?

Hey Nick,

Quick question, according to WiFi Alliance, the RTL8812BU is capable of 802.11mc FTM. Would you happen to know if this driver supports it? Or if not, how I could go about trying to develop/implement this feature on this driver to get the RTL8812BU to either act as a FTM initiator or responder?

Thanks!

Hi,
I want to change the sequence number in probe request to each 4 (ex: 0, 4, 8 ....), so far I have treid (rtw_mlme_ext.c: _issue_probereq()):
SetSeqNum(pwlanhdr, pmlmeext->mgnt_seq)
pmlmeext->mgnt_seq += 4
But no effect

Hello,

I am unable to make this driver work in Debian.

System configuration :

Debian 11 (bullseye), fully updated, kernel 5.9.0.1
Driver version : 5.8.7.4 (I saw #10 and tried to delete everything and reinstall but no luck)

But the device will not connect despite correct configuration used in /etc/network/interfaces

When I use wpa_supplicant I get this :

Using wpa_cli

Note that I succeeded once with scanning but at the last step (enable_network) it threw a firmware error and errored out. Sadly I did not copy the message.

Let me know if you need more information !

EDIT : purely informative, this driver : https://github.com/RinCat/RTL88x2BU-Linux-Driver works but only in USB 2.0 mode (crashed when I attempted to transfer a file when in USB 3.0 mode)

All,

Maintaining 5 Realtek out-of-kernel drivers as well as the informational sites related to using USB adapters on Linux is something that I enjoy but I have some requests and information I want to pass on. Most of the issues that are reported are not bugs but are configuration and setup issues. I am requesting anyone with knowledge on the subject being reported to offer help. Any issues that you can help resolve allows me to work on the things you really need me working on... like keeping these drivers working on new kernels as they are released.

If you are reporting an issue, please give us a statement about what you are trying to accomplish with your setup, the pertinent hardware and software details, exactly what the problem is and what the results should be and lastly, please provide the steps necessary to duplicate the issue. These drivers can and do work on a vast number of operating systems and hardware combinations so you need to set the table for those that can help you.

Note: My experience maintaining and using these drivers causes me to offer this advice. Many Linux users would be better served with adapters that do not use these Realtek drivers. These Realtek drivers are not Linux Wireless standards compliant. This causes a variety of issues when using various apps and utilities. Realtek does not release these drivers publicly and they do not support them. Have you tried to report a bug to Realtek lately? My recommendation to most Linux users is to use usb adapters that use in-kernel drivers as those drivers do support Linux Wireless standards and it is possible to report bugs. To that end, I have established this site:

https://github.com/morrownr/USB-WiFi

Do I plan to keep maintaining these Realtek drivers? Yes, I have and support adapters that use the Realtek chipsets. Will I be buying new adapters that use Realtek chipsets? No, not as long as there are good alternatives that are properly supported.

Comments welcome.

Regards,

Nick

Have just upgraded my RPI3B. New kernel. New kernel source (both version 20201201-1). Compilation of the 88x2bu driver failed due to the headers 5.4.79 not having been 'fixed' for 64-bit compilation. Consequently, no 88x2bu 64-bit driver!

This has happened before and will probably happen again. I'd caution anyone who's running 64-bit PiOS or DietPi NOT to upgrade the kernel until the headers have been fixed. A fresh 64-bit DietPi install will also fail because it runs an 'upgrade' and 'dist-upgrade' as part of the install/configuration process.

I'm reverting to 32-bit as a consequence of my dependency on the 88x2bu driver.

I have a 5 GHz usb wifi dongle and router, but it uses the 2.4 GHz channel. I am using Ubuntu 20.10 arm64 on Raspberry Pi 4.

Hi!

Successfully deployed on RaspberryPi 4 under Ubuntu Bionic Beaver.

But.

Unable to dump traffic in 80MHz channels. HT40+ and HT40- works fine but 80MHz can show me only Management frames. And I know that there is data, because there is transmission that I can see with my Intel ax200 chipset and in Radiotap info there is 80MHz.

TP-Link Archer T4U V3. RTL8812BU.

In Usb2.0 mode everything working fine, when switch to usb3.0 ap is not working with following error message:

nl80211: beacon_ies - hexdump(len=6): 7f 04 00 00 00 02
nl80211: proberesp_ies - hexdump(len=6): 7f 04 00 00 00 02
nl80211: assocresp_ies - hexdump(len=6): 7f 04 00 00 00 02
nl80211: Beacon set failed: -22 (Invalid argument)
Failed to set beacon parameters

I use rpi4 8gb with ubuntu server 20.04.2.

Is it possible to make 88x2BU runs softap and p2p go concurrently? or enable multiple softap at the same time?

Hello, I've been trying to get my rtl8812bu adapter working with Kali Linux on my Pi 4B and I was recommended this driver, however upon successfully building/installing it, I'm unable to do anything with the adapter.
If I try to bring it UP, set it into monitor mode, etc it throws an "Operation not permitted" error. I've run the 64 bit Raspberry Pi script and the fix described in #8 to no avail (though #8 did fix build errors I had)

When enable usb3.0 the rpi4 onboard 2.4Ghz band ap stop working, and any other wifi adapter has the same issue, stop working on 2.4Ghz band ap, I've tested netgear A6120 and asus ac51 all these can't work on 2.4Ghz, seems have serious interference!

Hi, i've problem with driver, i followed the instruction and after reboot nothing changed, so i check that the driver was loaded with lsmod, but it wasn't there, so i loaded manually with modprobe but also nothing

wifi stick: TP-Link Archer T3U Plus with 8822bu chipset
distro: xubuntu-20.04

hello, thanks for your work.
do you know how it compare to others 88x2bu drivers like Rincat's (the one I'm using) and cilynx's

I will try it when getting back home, but if you know some details that make this repo "better" than the other, I would like to know so I can change to this driver, thanks

Does it support wifi packet injection?

Hi, I am running in Linux 20.04
I am trying to use MAC randomization by defining the macro #CONFIG_RTW_CFGVENDOR_RANDOM_MAC_OUI in drv.types.h, but during compilation I get:
ERROR: modpost: "rtw_hal_set_pno_random_get_mac_addr" [full_path] undefined!
ERROR: modpost: "rtw_hal_set_hw_mac_addr" [full_path] undefined!

Well I went with the Cudy WU100s like many recommended. I am so close to finally having my WIFI set up I can feel it. I'll keep working on it regardless. I am stuck on Part 5 of this Install if you have any more advice to offer. I have the driver on CD, USB, can download from the Internet using a Hotspot, and have it in a tar.gz file through /Home/Jimmy/Project/. For whatever reason I can't seem to access once I switch to the Terminal. No such file or directory. I figured the CD only has Windows/MAC driver. Should I do root@linux since I'm on Linux Mint and not Ubuntu? https://newwezhanoss.oss-cn-hangzhou.aliyuncs.com/contents/sitefiles2019/10096568/files/281895..pdf?Expires=1612638716&OSSAccessKeyId=LTAIekGM1705vEQp&Signature=9heL83c+ZueYqtoPEFIop1dca2k=&response-content-disposition=inline;filename=RTL88x2BU%20linux%20Installation%20guide.pdf&response-content-type=application/pdf
Edit 1: I found the Realtek RTL811 under Network connections but can't seem to connect to this device.

Device: Cudy AC1300 WU1300S (0bda:b812)
Distro: Pop OS 20.04
Kernel: 5.8.0-7642-generic

Video evidence with dmesg -w

• It's connected via USB 3 directly to the motherboard. I tried rtw_switch_usb_mode=1, to no avail.
• This didn't happen when I installed the driver. It started happening after a reboot.
• Unplugging it and plugging it back in fixed it. I can't reproduce now even after a reboot. Thought it was still worth tracking.

P.S. Thanks for your valuable work.

Hi Developer

Hi,
it might be strange but I have noticed with the latest version of the driver a strange behavior. I check the txpower power from time to time and I notice that it changes from 20 up to 23 dBm. I swear I don't touch the txpower neither me nor a script. I have tested other similar drivers but its only with this one that I noticed it. My dongle is a T4U v.3

To make my self clear, I don't consider it as a problem I just want to mention it because it's kinda strange.

Could you please give advice on how to interrogate, and potentially modify, the various driver options found when you issue the "ls /sys/module/88x2bu/parameters" command?

Thanks in advance.
