Hi,

i am using a RaspberryPi 4B and a USB-Wifi Adapter with RTL8822bu chipset.
After installing the driver, there are two new devices showing up (wlan1 and wlan2).

How can I remove that wifi adapter?

The manual installation of this driver on ubuntu 2022.04 with the 5.15 kernel on a raspberry pi may have an error

if you run into an issue concerning -mabi options being incorrect then the solution is to specify the architecture during the make step.

So the new steps are as follows

make clean
make ARCH="arm64"
sudo make install
reboot.

The only change is to specify that arm64 is architecture.

Hi Nick & Team,

first of all, thank you for all the hard work maintaining those drivers and guides! They are very well written!

I had a "TP-Link Archer T4U ver.3" lying around and wanted to try using it on my RPi 4 as an access point. First of all: it worked! (maybe you want to add it to the list of supported devices) It is delivering very decent speeds:

[ ID]   Interval         Transfer      Bitrate          Retr
[  5]   0.00-90.00  sec  2.89 GBytes   276 Mbits/sec    0             sender
[  5]   0.00-90.01  sec  2.89 GBytes   276 Mbits/sec                  receiver

The only issue is, that it works only on channel 36 for me. If I set channel=0 to initiate ACS, unfortunately hostapd exits with the following log:

wlan1: interface state COUNTRY_UPDATE->ACS
wlan1: ACS-STARTED 
Interface initialization will be completed in a callback (ACS)
ctrl_iface not configured!
nl80211: Drv Event 33 (NL80211_CMD_TRIGGER_SCAN) received for wlan1

wlan1: Event SCAN_STARTED (47) received
Unknown event 47
nl80211: Drv Event 34 (NL80211_CMD_NEW_SCAN_RESULTS) received for wlan1

Please feel free to close this issue if this is rather a hostapd issue. If anything, I hope this ticket provides some testing results for you.

I followed the instructions that you provided for Ubuntu. The driver seemed to install correctly. The wifi adapter LED is now blinking and it is able see available wifi connections. The problem is that I am unable to connect to the wifi. It repeatedly asks for the wifi password and when I enter in the correct password, it asks again.

According to #2, we know this adapter does not run a 5GHz AP well under usb3 mode on a raspberry pi. However, this issue cannot be reproduced on a x86 computer.

It seems the only file changed when installing on a RPi comparing to on a PC is the make file. So maybe we should leave the makefile untouched?

So please do this experiment:

• Compile and install this driver on a pi WITHOUT running raspi32.sh
• Setup usb3 mode and 5Ghz AP
• Do the iperf test for at least 30s to see if the connection drops

Hello,

I have ASUSTek Computer, Inc. ASUS USB-AC58 USB Wireless adapter. I have successfully installed driver on Fedora 36 with kernel 5.18.7-200.fc36.x86_64. Everything works as expected I have internet connection, signal is great but every time when I reboot or turn on my PC I have to switch from usb 1 to usb 2 (after another reboot from usb 2 to usb 1). Because if I dont do this ritual I am connected to my wifi network but I dont have a internet connection. When I switch adapter from one usb port to another one after that I have internet connection. I have tried to install and reinstall driver many times but it wont help.

I have this installed on OMV 5 Debian. It connects but the link is slow. I don't have access to the router I connect to (shared) and I can't see the link speed in Debian CLI

Any ideas?

31 dec 2021 tested with 1. dlink dwa 182 rev d1 - on entering monitor mode computer freezes and even cursor doesnt move. if any audio playing in the background goes into a short audio loop. Cannot shut down as process doesnt terminate at all. have to disconnect power instead.
2. TP LINK Archer t3u plus v1.0- terminal freezes on monitor mode, cursor still works but cannot shut down as process doesnt terminate at all. have to disconnect power instead.

Rincat release seems to work fine. Had to uninstall yours, if you update this repo please let me know.

Nick,

I'm a relative Linux newbie, but wanted to mention that your driver and cilynx's won't install/build on my Ubuntu 18.04 system if I am running Kernels 5.10 OR 5.15.

Researched on github and forums for solutions and none worked. Had EXACTLY the same problem as this gentleman:
#11

Was using GCC version 11.2 and also fully updated headers/modules for kernels 5.10 and 5.15.

Since I do not have the required technical skill to troubleshoot further, I cleaned my DKMS, uninstalled any failed driver installs, and rolled back my kernel to 5.4 LTS. Et Voila, reinstallation worked perfectly.

I also wanted to take a moment to thank you for your efforts and for your investment in this driver. It's true that Realtek devices are going to be more and more problematic for Linux users in the future, but your driver has saved me the expense of buying new hardware. Appreciate you!

Error:
* dkms: running auto installation service for kernel 5.15.0-41-generic Error! Could not locate dkms.conf file. File: /var/lib/dkms/rtl88x2bu/5.2.4.4/source/dkms.conf does not exist. ...fail! run-parts: /etc/kernel/postinst.d/dkms exited with return code 4

There are two directories in /var/lib/dkms/rtl88x2bu/ 5.2.4.4 with a wrong link to source and 5.13.1, deleting 5.2.4.4 one solved the problem

Hi, morrownr!

This piece of code. Where did you find it? Is look like the same I wrote a few months ago.
https://github.com/ivanovborislav/rtl88x2bu.git, hal/rtl8822b/usb/rtl8822bu_led.c.
Everything is OK, just point the source. This is right.

Hi Nick (if I may),

first of all, many thanks for this driver. This is the best and most stable driver for my card. I have no problems, but the speed is slower in comparison with the same card under Windows. For my Internet connection the download speed it is 200Mb at best while under Windows is almost maximum at 300Mb. It's not a big deal however I decided to report this.

I've tested different kernels (LTS and latest in Arch) and all the ports in my computer (HP MP9 G2 Retail System). My Windows and Linux machines are close to each other and the router is nearby (about 2m). I'm happy to provide some more details if you need some.

Cheers!

Tested on TP-LINK Archer T4U v3 (Realtek RTL8812BU) works perfectly

• Aircrack 1.6

OS Kali 5.14

• Aircrack 1.6
• Wifite2 2.5.8

First of all, thank you for maintaining this repo. It is the only driver that works for me. Without it, I would have to bear with a long cable running across the entire house.

Short story, install-driver.sh succeeds but the usb adapter won't work (blinks for a few seconds then off). On the other hand, install-driver-no-dkms.sh works.

Here's the longer story. I have an old Dell precision T1500, it is running Ubuntu 20.04. I've been using the 88x2bu-5.8.7.4 driver for the past year and it worked fine until about two weeks ago when suddenly the system cannot recognize the usb wifi adapter. I removed the driver and tried to install-driver.sh again, but make failed with fatal error: net/ipx.h: No such file or directory (due to changes in kernel 5.15?). Then I found this new repo 88x2bu-20210702. The install-driver.sh script runs successfully, dkms confirms that the driver is installed. The usb adapter blinks for a couple of seconds, giving a list of available wifi networks, then the light turns off. Connecting to the networks failed with the message activation of network connection failed (light on usb adapter never turns on again). After multiple unsuccessful attempts with different combinations of options, I decided to give install-driver-no-dkms.sh a try, and voila, it works! I have no clue where (or which log) to look for potential causes of the issue but thought posting it here may be helpful.

More details:
Desktop: Dell precision T1500, only has usb 2.0. The usb adapter says usb 3.0 on it but it has been working fine with a decent speed (60/10 Mbps comparing to 75/11 Mbps on my tablet which is on the same network).

How to fix Mode monitor airodump-ng wlan1 fixed channel 1

computer crashes when start monitor mode on TP-Link t4u v3

Ever since the kernel 5.18 has been released, I've been in a misery of trying to fix my Wifi adapter. For some specific reason, the internet speed drops to 20mb per second from 300mb per second. Therefore I have reverted back to 5.17 kernel for the meantime.

I personally think this issue exists due to the fact that linux 5.18 introduced new wifi adapters to the kernel, making the latest drivers for 88x2bu to be broken possibly?

Regards

Anyidea about this error another Drivers have the same problem here... i hope you can help me @morrownr :)

Hi

The driver is successfully installed into the Pi 4 with 64bit Pi OS. The onboard wifi is disabled via the /boot/config.txt file. After the reboot, the wlan0 shows a list of available wifi endpoints. Once a home wifi is selected, the ESSID shows up correctly in iwconfig result. However, after a few seconds, it is back to unassociated. I tried so many time on either 2.4G or 5G wifi. It never connects. Anyone knows what is going on there?

PS: The onboard wifi connects without any issue.
Thanks,
Wilson

new commit will let aircrack-ng can‘t switch to monitor mode in kali, but in 36f5ceb
commit without this problem.

thanks for your job !

Hello, I have a generic Amazon 8812bu dongle and I'm having some issues.

I installed this driver without any issue. I selected Concurrent_Mode during install because I want to have both a 5Ghz and a 2.4Ghz AP.

I'm using Mint 20.3 and I used the GUI to set my two wireless AP as following:

But as far as I see, the access points are working in 802.11n mode only, not ac. And the bit-rate is way too low, 144.4 Mbps is far from the advertised numbers (5GHz (867Mbps) / 2.4GHz (300Mbps)). I verified this by connecting to the networks with my phone and seeing that the AP is "WiFi 4", not 5.

Rebooting or doing $ sudo systemctl restart NetworkManager doesn't make a difference.

This is the output from iwconfig:

$ iwconfig
wlx1ebfcee632b8  IEEE 802.11bgn  ESSID:"Home"  Nickname:"WIFI@RTL88X2BU"
          Mode:Master  Frequency:2.412 GHz  Access Point: 1E:BF:CE:E6:32:B8

wlx1cbfcee632b8  IEEE 802.11bgn  ESSID:"Home_5G"  Nickname:"WIFI@RTL88X2BU"
          Mode:Master  Frequency:2.412 GHz  Access Point: 1C:BF:CE:E6:32:B8

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0

See? both AP are using IEEE 802.11bgn, Frequency:2.412 GHz and Bit Rate:144.4 Mb/s. 🤔

My dongle is connected to a USB3.0 port in the back on the computer, directly to the motherboard (An Asus MAXIMUS VI HERO).

I also tried to manually edit /etc/modprobe.d/88x2bu.conf to define my country code and the wireless mode, but this didn't fix the issue.

options 88x2bu rtw_drv_log_level=0 rtw_led_ctrl=1 rtw_vht_enable=1 rtw_power_mgnt=1 rtw_switch_usb_mode=1 rtw_country_code=ES rtw_wireless_mode=95

My goal is to have a 2.4ghz and a 5ghz network to extend Wi-Fi coverage to my garage where I have some smartplugs that need 2.4ghz Wi-Fi but depending on the day they don't have a good enough connection. The 5ghz network would be used so phones and other mobile devices don't drop connection when they are brought to the garage.

The computer I'm using for this task is an old Intel i5 4670K based computer that I'm using as a "small" server and it's connected to the network using ethernet and it's getting a stable Gigabit connection from a nearby switch.

When reporting problems, remember that the people that will attempt to help you do not know what Linux distro you have. Painting a picture that includes the distro you are using and a brief description of the problem is important.

Checklist regarding what to include:

• A brief description of the problem.
• Paste the screen output provided by the install-driver.sh script.
• The name and version of the Linux distro you are using.
• The information obtained with the below command.

sudo lsusb; rfkill list all; dkms status; iw dev; iw reg get

Thank you

Hi Nick,
Slackware's main site is slackware.com, and there are many mirrors. Slackware.uk is a fast one, and Alien Bob hangs his stuff on slackware.nl. Slackware packages are everything installed by 'make install' - programs, libs, shares, docs & includes. There's no dependency tracking, but there is ldd:). You can upgrade, downgrade, install non_standard, etc. I have a /tmp/pack directory always. The packages are made by 'make DESTDIR=/tmp/pack install; cd /tmp/pack; makepkg ../my_package.txz; rm -rf /tmp/pack/*
Slackware has no systemd, uses /lib for 32bit and /lib64 for 64bit libs, prefers old stuff over new and expects you to know a little. Scripts are usually bash scripts. There is also significant external repositories, arm ports even a risc-V with slarm64. Alien Bob (A slackware dev) supplies useful stuff: 64+32 bit versions of wine, glibc & gcc(the latter 2 needed for multilib); his 32bit compatibility libs(or multilib); an ungoogled version of Chromium; piles of stuff you wanted but couldn't get - like restricted codecs in vlc for the Excited States and unrestricted for the rest of the world. Multilib is needed for running 32bit windows applications (which is most of them) on a 64bit OS.

My 88x2bu is not going. The module appears sensitive to multithreaded builds. I have two git clones here(well organised, amn't I?) and two modules, and diff shows them as differing :-o. The infuriating thing for me was that I had the dongle working in my shiny new pc, but updated the kernel trying to get kernel support for the RTL8811CU, and lost my module. I could never get it going again. This thread refers https://www.linuxquestions.org/questions/linux-hardware-18/hardware-problem-with-wifi-dongle-4175714726/ and saves a lot of typing. I installed my OS on this new pc by installing the basics, then restoring a backup from my recently retired laptop. I still have the laptop. The same dongle works in that! It has the same crash in dmesg when I insert the dongle, 'ifconfig wlan2 up' only takes 2-3 seconds, I get good upload & download, but that has it's own highly sensitive built-in Atheros wifi hardware as well, which I have to disable to test the dongle.

I can't get debug type feedback from ifconfig or iw while they are sitting quietly for 10 seconds - I'd love a suggestion on that score. I know strace & gdb are included with slackware, but I've never used them. Ditto the insertion crash, which happens every time.

So as you see, I've kinda fingered my shiny new pc as the problem, although it worked there before. And the dongle is obviously a POS. (usb id: 0bda:b812). Any ideas welcome

rtl88x2bu/5.13.1: added

Hello, I am quite new to linux, so may have some dumb errors. I am running CentOS 7 and was trying to install the driver but when I used automated script it gave me dkms error =10, I tried to run it manually through make but also without success. please find the output of the terminal in the file attached. \I would appreciate if you can advice where I should move from here. Thank you for your help and detailed instructions
file.txt

The driver does not work on ubuntu kernel: 5.11.0-38-generic(Realtek) with NetGear A6150.
I have successful used 88x2bu driver on ubuntu kernel: 5.8(Realtek) but it does not work after I upgrade ubuntu to 5.11(Realtek).
So I reinstalled 88x2bu-20210702, it still does not work.
No wireless interface show in 'lshw -C network'.
Could you have a check? Thank you.

Build fails on Fedora 35 kernel 5.14.16.
Any idea ?

Can you please tell me what are the average or maximum throughput for 2.4 and 5 GHz on these two AC WiFi cards jjPlus WMU6202 and Edimax EW-7822ULC ?

I plan to buy one of these and put it on my mini PC and configure them to work as an access point.

Thank you.

My system is a raspberry pi 3b+ equipped with piCorePlayer v8.2 64 bit and a Tp-Link Archer T3U Plus wifi dongle.
The wifi dongle is not recognized out of the box, thus I ran the procedure for generating a dedicated driver for RTL8812BU chipset.
The selected kernel was 5.15.35-pcpCore-v8. Therefore I launched the following command:
make KVER=5.15.35-pcpCore-v8 -j 1

The processs ended with errors, as follows:

The wifi dongle is Device 004.

Despite the errors, I ran the script to recompile the kernel (adding the driver for RTL8812BU). Predictably that script ended with errors as follows:

Hi, testing a BrosTrend AC1200 adapter that should have an RTL8812BU chipset.

The item appears to work with this driver, both as a USB2 and as a USB3 device. My issue is that it seems extremely sensitive to the antenna orientation. You get the orientation wrong (even by a few degrees) and immediately you get extremely erratic ping times while for another orientation the ping times are very repeatable. By erratic I mean that pinging a remote site periodically goes from the expected 100ms up to 1-2s. for 3-4 packets every 20-40 packets and then back to normal, which basically makes the connection unusable. When this happens, at times the connection breaks completely (network unreachable).

There are two weird things about this:

• when this happens there is no actual connection drop from the access point (i.e., you get network unreachable but the adapter stays connected to the router);
• when you get the erratic ping times, there is no sign of connection degradation in terms of "Signal strenght" reported by the adapter.

In the past I had a router doing something similar. It was meant to have a super-smart "adaptive" beamforming and noise filtering technology but the adaptive algorithm was periodically running into some crisis. Eventually, I found that it was possible to disable the adaptive behavior and with that the router behaved regularly.

Has anything like that been experienced by others with this chipset?
Are there any params controlling the beamforming or the adaptive behavior of the device?

To deal with a graphics issue, I upgraded to kernel (& headers) 5.18.14. The '-mharden-sls=all' option has gone in as a security measure by default for 5.18.x. The compile bales out thusly: bash-5.1$ make -j6 make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules/5.18.14/build M=/home/dec/Downloads/88x2bu-20210702 modules make[1]: Entering directory '/usr/src/linux-5.18.14' warning: the compiler differs from the one used to build the kernel The kernel was built by: gcc (GCC) 12.1.0 You are using: gcc (GCC) 11.2.0 CC [M] /home/dec/Downloads/88x2bu-20210702/core/rtw_cmd.o CC [M] /home/dec/Downloads/88x2bu-20210702/core/rtw_security.o CC [M] /home/dec/Downloads/88x2bu-20210702/core/rtw_debug.o CC [M] /home/dec/Downloads/88x2bu-20210702/core/rtw_io.o CC [M] /home/dec/Downloads/88x2bu-20210702/core/rtw_ioctl_query.o CC [M] /home/dec/Downloads/88x2bu-20210702/core/rtw_ioctl_set.o gcc: error: unrecognized command-line option ‘-mharden-sls=all’ gcc: error: unrecognized command-line option ‘-mharden-sls=all’ make[2]: *** [scripts/Makefile.build:289: /home/dec/Downloads/88x2bu-20210702/core/rtw_io.o] Error 1 make[2]: *** Waiting for unfinished jobs.... make[2]: *** [scripts/Makefile.build:289: /home/dec/Downloads/88x2bu-20210702/core/rtw_ioctl_query.o] Error 1 gcc: error: unrecognized command-line option ‘-mharden-sls=all’ gcc: error: unrecognized command-line option ‘-mharden-sls=all’ make[2]: *** [scripts/Makefile.build:289: /home/dec/Downloads/88x2bu-20210702/core/rtw_cmd.o] Error 1 make[2]: *** [scripts/Makefile.build:289: /home/dec/Downloads/88x2bu-20210702/core/rtw_ioctl_set.o] Error 1 gcc: error: unrecognized command-line option ‘-mharden-sls=all’ make[2]: *** [scripts/Makefile.build:289: /home/dec/Downloads/88x2bu-20210702/core/rtw_security.o] Error 1 gcc: error: unrecognized command-line option ‘-mharden-sls=all’ make[2]: *** [scripts/Makefile.build:289: /home/dec/Downloads/88x2bu-20210702/core/rtw_debug.o] Error 1 make[1]: *** [Makefile:1838: /home/dec/Downloads/88x2bu-20210702] Error 2 make[1]: Leaving directory '/usr/src/linux-5.18.14' make: *** [Makefile:2499: modules] Error 2 bash-5.1$

I still have your module compiled for the 5.15.27 kernel, so this isn't a disasater, just a heads up.

I try so to install the driver on WSL2 Ubuntu 20.04 and get fail with auto dkms or no_dksm.sh and also install by manual but still got no luck.
$lsusb I got :

then I do
$sudo modprobe btusb
and I got

but the bluetoothctl and hcitool dev cannot work because cannot found the bluetooth adapter.
try to remove driver and install again still cannot solve the problem.

Please check a log file below and help me fix that build error
Thanks in advance.

I am posting this issue as a place for everyone to add the information they have in an effort to fix the issue.

Bug: This appears to only happen when the driver is under heavy load in 5 GHz AP mode while USB3 is active on a RasPi4B. The AP will simply drop the client and the only way to get things going again is to reboot the AP. Testing has shown that if USB2 is active, there is no problem so this is a very specific issue.

Note: This issue is specific to Raspberry Pi 4B hardware as far as we can tell.

Is it possible to install the driver on a phone?

I have an S20 FE 5G but whenever I plug in the wifi adapter to my phone the wrong driver shows up, 88XXau instead of 88XXBu

I tested this driver on my computer and it worked perfectly, but I don't know how to get it working on my phone

Hi!

I've got a very strange case here.
My setup first.
I'm using a raspberry as a wifi to wifi router. The raspberry pi 4B is connected to a wifi modem/router that doesn't support DNS settings nor DynDNS etc. As I can't access it directly, I'm using my raspberry pi and connect it to it. A USB WiFi in ap mode is connected to the raspberry pi and other devices connect to this AP. On the raspberry pi I run a pi-hole with a custom DNS setting. A iptables rule forwards the requests from the wifi ap ip address to the wifi module that is connected to the modem/router.

Now the problem:
If I'm near the hotspot, I can connect and access to the internet without any trouble. But if I'm about 10m away (WiFi strength is still good with about 80%), then I can't connect to the hotspot. It always stops at obtaining the IP address and fails there.

OS is Ubuntu Server 22.04.
My USB WiFi is EDUP EP-AC1686. It uses the RTL8812BU driver.
Driver settings:

options 88x2bu rtw_drv_log_level=0 rtw_led_ctrl=0 rtw_vht_enable=1 rtw_power_mgnt=0 rtw_switch_usb_mode=2

Hostapd settings:

interface=wlxe84e069cc6e0
driver=nl80211
ssid=myaccesspoint
hw_mode=g
channel=7
wmm_enabled=0
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_passphrase=mypassword
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP

Any ideas what could be the cause?

I have noticed some concerns regarding txpower and range. Maybe this is a topic we should explore during testing to see if we can determine if there is a problem and if so, how bad is the problem.

Let me start by saying that I have expressed concerns in other locations about the quality of many adapters that are based on the rtl8812bu and rtl8811cu chipsets. The rock bottom prices some of the adapters based on these chipsets sell for should be an indication that corners will be cut and performance can suffer. I have 4 adapters based on the 8812bu chipset. Even among this small subset of adapters, there is a large variation in quality and capability.

The best indication that we will have that there is a problem with this driver is if we see a large difference in the range with a specific adapter that is tested with this driver and then with a Windows or OSX driver. I have no systems running Windows or OSX nor do I have access to them so hopefully some of the rest of you do and can take on looking at this issue from a comparison standpoint.

The command to change txpower in this driver is:

sudo iw dev wlxb44bd623a7XX set txpower fixed 2200

The default txpower for the adapter I am testing was set to 22 dBm. I ran the power down to 15 dBm and then up to 30 dBm and watched the results on 2 separate apps that show signal strength. I saw movements that indicated the changes worked. Not all adapters will allow changes to be made as the setting may be locked or limited in firmware so it will depend on the adapter you have.

Keep in mind that our mission here is to test and get things ready for a public release, not get lost in long philosophical discussions. Can we improve the user experience with better documentation, better settings or even code changes? Let's find out.

Nick

Request that you test and report any problems. Specific bugs should be reported by opening a new issue. Discussion can go here.

Of note: I am requesting that you follow the documentation so as to check and provide correction to the documentation. It could be easy to miss issues in the documentation if you used the prior version of this driver.

Of particular interest is AP mode operation. Hopefully AP mode is MUCH better now.

Nick

Hi,

I am trying to use this driver suite with Kali Linux ARM64 Raspberry pi 4 2021.4 which unfortunately for me and any users in similar situation - has changed to the Re4son Kernel.

What would need to be done to assist with the modification of this driver suite build / install scripts to support the Re4son kernel as part of kali-linux-2021.4-rpi-arm64.img?

For more information I am trying to setup Archer T4U Plus which may be suitable for this driver suite if the new addition can be made / assisted.

Thanks

I built a new kernel for the Raspberry pi 4 then built and installed the 88x2bu-20210702 driver, for a TP-Link USB Wi-Fi adapter I have never used before. It seems to work fine as a wifi interface (no AP mode, no 867 MHz, no concurrent mode, USB2). But I’m getting kernel error messages in /var/log/messages and dmesg when the driver is loaded at boot.

The adapter is a TP-Link Archer 3U Plus, connected to a USB2 hub. I know USB2 is not ideal, but it would be difficult to replace it with a USB3 hub in my existing project. I am connected to a 2.4 GHz AP so throughput should not be an issue.

Thanks in advance for any help you can offer.

Hello,

I am using a kernel built with Clang / LLVM.

Wi-Fi driver installation failed because of compiler option for Clang
so I would like to build the driver with Clang / LLVM.
However I couldn't find how to.

Could I use Clang / LLVM?

Thank you in advance.

rtl88x2bu/5.13.1: added

I use Gembird WNP-UA1300-02, it's a RTL8812BU chipset USB 3.0 wifi adapter. On every startup the connection to wifi network takes up to 10 minutes and fails at the end, so I have to forget the network, enter the password again and then it connects in a few seconds.

Here is my 88x2bu.conf:
options 88x2bu rtw_drv_log_level=0 rtw_led_ctrl=1 rtw_vht_enable=1 rtw_power_mgnt=0 rtw_switch_usb_mode=0

I set rtw_power_mgn to 0, that improved connection stability and now I am able to just unplug the adapter and plug it to another usb port, with power saving adapter was not starting up after replug to different port.
