there's a new linux kernel 5.8.0-2parrot1-amd64 released recently but this drivers don't work with it'
the drivers worked well for me on kernel 5.7.0-2parrot2-amd64

edit to add - this was after upgrading from 20.10 to 21.04 beta

Followed steps in readme.

Guessing that the current code is not compatible with the kernel version.

hi i am using rhel8.
The kernel I use is 4.18.0-240.1.1.el8_3.x86_64 from the kernel-lt package.

I also tried the kernel-ml (5.10 mainline kernel) package from the epel 8 repository, but I could not use it because I got the kernel panic.

I followed these steps. I initially built the source:

Hello,

Bluetooth on my debian machine stopped working a couple of days ago. I have been trying to find the root of the problem but haven't been able to. So now I resort to ask for help.

My motherboard is

Asus ROG Strix Z370-I Gaming Mini ITX LGA1151 Motherboard
which has the Realtek Semiconductor Co., Ltd. RTL8822BE 802.11a/b/g/n/ac WiFi adapter. This is the device that provides bluetooth connection as well.

Error log:

• bluetoothctl: No default controller available
• hcitool dev: Devices: . hcitool device is empty.
• systemctl start hciuart: Failed to start hciuart.service: Unit hciuart.service not found.

• sudo rfkill list all: Only 'Wireless LAN' shows up. No bluetooth.
• hciconfig scan: Can't get device info: No such device
• sudo bluetoothd -n -d: bunch of 'Key file does not have key' errors. Then 'Name already in use' and 'Unable to get on D-Bus'
• bt-adapter -l: No adapters found
• sudo cat /var/log/syslog: [haven't really examined closely]

Other notes:

I might have to black list some of those above, but they look the same as someone who had their bluetooth working properly, so I don't know if the issue is here.

I've been hit with issues that I have solved on my own before with my general knowledge of how this driver works, but this issue in particular got me fearing two things:
- Either there is much more I still don't understand about the inner workings of this driver.
- Or my physical bluetooth card is damaged and this is a hardware issue. (I prefer to be an idiot that doesn't know how this system works rather than my motherboard having a component fried)

Anyway, please help shed some light into what might be causing this issue. I would really appreciate it.

Hi,

First of all, thank you very much for your work, your driver is the only one working on ubuntu 20.04.1 for my Realtek 8822be card, it's a life saver.
I know you don't want to change the code for Ubuntu but i don't think the issue i stumble upon is ubuntu related.

Anyway, here's the thing. On a fresh install, i installed your driver as you instructed and it worked like a charm (after setting the disable_aspm option to Y for rtw_pci, this might be ubuntu related).

But, after the first kernel upgrade, even though i installed the drivers again as you instructed, they wouldn't load on boot or with modprobe because rtwpci was in use. After a lot of head scratching, we figured out that on install the distro's drivers (rtwpci and rtw88) were not removed from /lib/modules/$(KVER)/kernel/drivers/net/wireless/realtek/rtw88/ and backed up in ~/rtw88/backup_drivers.tar because that backup_drivers.tar file already existed from the previous install on the previous kernel.

I looked into the makefile and it appears to me that this eventuality is not taken into account, i think that a solution would be to replace in the makefile :

install: all
ifeq (,$(wildcard ./backup_drivers.tar))
	@echo Making backups
	@tar cPf backup_drivers.tar $(MODDESTDIR)
	@modprobe -rf rtwpci
	@modprobe -rf rtw88
	@rm -f $(MODDESTDIR)/rtw88*.ko*
	@rm -f $(MODDESTDIR)/rtwpci.ko*
endif

by

install: all
ifeq (,$(wildcard ./backup_drivers.tar))
	@echo Making backups
	@tar cPf backup_drivers.tar $(MODDESTDIR)
	@modprobe -rf rtwpci
	@modprobe -rf rtw88
	@rm -f $(MODDESTDIR)/rtw88*.ko*
	@rm -f $(MODDESTDIR)/rtwpci.ko*
else
	@echo Making backups
	@tar rPf backup_drivers.tar $(MODDESTDIR)
	@modprobe -rf rtwpci
	@modprobe -rf rtw88
	@rm -f $(MODDESTDIR)/rtw88*.ko*
	@rm -f $(MODDESTDIR)/rtwpci.ko*
endif

This is not a huge issue but i'm worried that it would create problems if one wants to use dkms to install your drivers.
Again, thank you very much for your work and i'm sorry if i'm making you waste your time with this.

Hi,

My laptop has an RTL8822BE Wifi/bluetooth controller.

All throughout the release of kernel 5.7 (almost every other subversion) my bluetooth has stopped showing up

Is this a known issue?

Hello, sorry for opening this issue. I have installed your driver, works well. But when i'm airmon-ng start wlan0 all OS is freezing. May be i'm not understand wich drivers must to be blacklisted. Can you give me some advise what to do

Thats so much of pain

There doesn't seem to be a way to reach you, so I'm filing an issue :^)

I spent an entire day trying to get ubuntu to work with my realtek card, and after building about a dozen driver projects, I was about to give up. Then I stumbled on a one-line mention of your rtw88 project and decided to give it a last try.

In just a couple of minutes I checked out your code, built it, and voila - everything works! I wanted to thank you for creating/maintaining this lifesaver - you rock!

I consider this issue closed.

after update to kernel 5.7.0-kali1
and got no wifi, i try use RTW88
and getting frezee use monitoring mode
before update kernel iam use rtlwifi_new and use monitor mode verry well?
any solution to use monitor mode again on this kernel?

Hello, does 8821ce driver in this repo support miracast?

I have used this repo for my rtl8822be chip for a long time with few issues while updating my kernel every few days.
Now it doesn't seem to work for at least this version, probably also the previous 1 or 2. I am running openSUSE tumbleweed with the 5.9.11-1-default kernel.
When I do dmesg, I see following errors:

Throughout the output, a couple of times the following error:

Hi here I am again.

I still have a Lenovo-IdeaPad-C340-14IWL, with a dual boot windows 10 and ubuntu.
I had ubuntu 20.10, but couldn't get the wifi working.
I reinstalled 20.10 clean and the same problem occurs.
I installed 18.04 and the same problem is there.

Sometimes wifi works and sometimes it does not. No wifi networks found / failed to activate wireless connection etc.

I notice that sometimes my laptop freezes every 10 seconds or so for a second, not just the mouse but everything. It might be related but could not find what to do about it.

Either way, I have spend hours and hours on this problem and it is very frustrating. Here is where I am at now. I don't know a lot about ubuntu, so please any help is really welcome.

lspci ouput
02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8822BE 802.11a/b/g/n/ac WiFi adapter (rev ff)

If understand this correctly means that I need a proper rtl_8822be driver. That is what I download here in this rtw88 repo.

lsmod | grep rtw output:
rtwpci 24576 0 rtw88 610304 1 rtwpci mac80211 851968 2 rtwpci,rtw88 cfg80211 712704 2 mac80211,rtw88

I did not blacklist anything, because I don't see conflicting drivers.

I sudo do
sudo modprobe rtw_8822be and it says
modprobe: ERROR: could not insert 'rtw_8822be': Exec format error

please, how can I simply have wifi working reliably? That is one of the essential things of having a laptop

Hi Larry,

Something is borked in your Makefile. If I patch it like this, the install step works again:

Before the r8822be staging driver got removed with linux 5.2, I could use 5GHz AP mode with this adapter just fine. Now, hostapd fails with the following message:

Channel 36 (primary) not allowed for AP mode, flags: 0x853 NO-IR
wlan0: IEEE 802.11 Configured channel (36) not found from the channel list of current mode (2) IEEE 802.11a
wlan0: IEEE 802.11 Hardware does not support configured channel
Could not select hw_mode and channel. (-3)

Is 5GHz AP mode not supported anymore with this driver?

I have a rtw8723_de card and experience an unstable connection. Reconnecting to the router gives me for a couple of minutes a stable and fast wireless connection and then it becomes unstable again.
Pinging my router I can see ping timings from 2ms to 1500ms.

Sometimes it becomes more stable, after some time, and I get consistent 2-10ms ping times .
Nothing is logged in dmesg or the system logfile, so I am not sure, what to look for. Signal strength is very good at all times (even when the ping times drop significantly). Any idea what to look for, to debug it further?
I am on kernel 5.7.7.

I got a similar issue to #22, in Ubuntu 18.04 live usb. When I make:

Hi,

This might not be the correct place to ask, i try nonetheless.
the new Kernel 5.8.0+ from repo https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
has these drivers built in.
I compiled it as a module, i need 8821ce.
When loading the module, i get the following in syslog:

Aug 10 10:53:34 localhost kernel: rtw_8821ce 0000:03:00.0: Firmware version 24.5.0, H2C version 12

Aug 10 10:53:34 localhost kernel: rtw_8821ce 0000:03:00.0: failed to setup chip information

I have the correct firmware placed in
/lib/firmware/rtw88/rtw8821c_fw.bin

Any idea how to fix this?

Thank you!

PD : I've just seen that this repo doesnt support rtl8723be. My bad.
Sorry for the inconvenience

I am using the rtw88 modules from kernel 5.10:

 $ lspci

But P2P mode is not supported:

	Supported interface modes:

		 * managed

Is there any plan to add P2P mode support in the drivers?

I see the closed issuse #38 is related to this. I am also trying to enable miracast (gnome-wireless-displays) on my laptop but it fails to work due to lacking support.

Ran the make command for this and it worked like a charm. However, I then learned that I do not have this device. How do I remove the files once installed / made (make)?

while running this command getting module not found error.
(base) naveen@nv:~/rtw88$ sudo modprobe -r rtl8723de

Hi ,

I installed this driver on my fedora 32 for testing purposes, But after testing when I tried to remove the driver using make uninstall its throwing below error

rm: cannot remove '/lib/modules/5.7.10-201.fc32.x86_64/kernel/drivers/net/wireless/realtek/rtw88/rtw_*.ko': No such file or directory
make: *** [Makefile:112: uninstall] Error 1

Also I noticed that my wireless stopped working after running make uninstall , How can I copy back original rtw88 drivers shipped with my os ?
PS: As a temporary fix I have switched to older kernel

thank you so much sir for this project , so much ! no linux has inbuilt driver for my wifi card , if you stop working on it then have to back to windows again :( , by the way I am using fedora 32 , and have succecfully installed the wifi driver from your repo , all working , but i cant make hotspot , fedora show that hotspot created by am not finding connections from others devices ,

I'm using 5.10.0-kali7-amd64 with RTL8723DE controller; following the steps wifi doesnt work. I've been watching and reading lot of info about but nothing has work.

No, no error during or after installing. I'm running in dual boot with Windows 10, could be this the cause of this malfunctioning?

Hi,

I have a lenovo ideapad C340 and since the update to ubuntu 20.04 have had no wifi.
I follow the guide step by step, but at sudo make install I get the problem: make: *** [Makefile:84: install] Error 1

Maybe this is of any help:
output for lspci -v:

	Kernel modules: rtw88_8822be, rtw_8822be

Any idea what I can do to get the driver properly installed?
Best,

Kewin

Dear Larry,
Some command aren't correct in your Makefile. I'd try to fix this problem and solved it correcting these steps:

I have been using this driver without issues for a while, but I just reinstalled my system and it doesn't work anymore. It literally worked yesterday.

The title is pretty much self explanatory.

i give you some output of maybe useful commands

dmseg doesn't have anything useful on bluetooth side

let me know if you need anything more

The check for fsleep in commit accc527 doesn't work - on newer kernels the build fails because fsleep gets redefined. I tried finding out more about the way you checked for fsleep being defined but didn't find any information about whether this is supposed to work. An alternative way would apparently be using the __weak__ function attribute, but I couldn't get that to work either. For now I just removed the definition in main.h as a workaround for me.

in my hp laptop with rtl8723de chip WiFi speed is unstable and too slow. ping to modem is too high and also packet loss is there.
I'm getting full speed on windows and also via external WiFi adaptor. Tried manjaro , popOS, OpenSuse ,Garuda Linux with kernel 5.8 , 5.9 , 5.10 & 5.11 same issue is in all WiFi worked otb in all distros but this issue exist.
I've installed this driver and same issue facing here too

Results of my actual WiFi speed and speed I'm getting is attached below.
Please do help me out to get it working.

Hi,

First, let me thank you for your help, it is greatly appreciated.

I'm running into an issue and I'm not sure how to fix it, I have read the README several times now.

On your readme it says:

The correct ones are:
rtw_8723de rtw_8723d rtw_8822be rtw_8822b rtw_8822ce rtw_8822c rtw_core and rtw_pci

Is this sentence missing rtw_8821ce ?

When I do lsmod | grep rtw I get this:

rtw_8821ce 0
rtw_8821c 1 rtw_8821ce
rtw_pci 1 rtw_8821ce
rtw_core 2 rtw_8821c,rtw_pci
mac80211 2 rtw_core,rtw_pci
cfg80211 3 rtw_core,mac80211,8821ce

I guess my questions is, how do I know if I'm using your driver, or the one from:

https://github.com/tomaspinho/rtl8821ce

Because I forgot which one I installed.

Is it possible that they have the same name?

And how do I switch between them if they have the same name?

I'm getting really weak wifi signal and don't know how to fix it.

Thank you so much!

After installing Debian 10, install the firmware to be able to use Wifi, from rtw88.git.
I was able to use the Wifi of my HP Proobok.
However, after a while, the following error begins to be generated and after that, my notebook is crach.
I attach features of my OS and errors before crash.

Thank you very much for your help!

solving by deleting it, on my system after that maked sucessfuly.

First, thank you so much for maintaining this repository. I've been using the driver for quite some time and it's made my lenovo yoga run like a champ with Kali.

During the latest kernel upgrade I received the following gcc errors when running make

Any thoughts - I've not come accross this until this kernel. Thanks again!

I have a laptop with an rtl8821ce wifi adapter. 5GHz works great with this driver, but 2.4 GHz has very weak reception. It won't even pick up my home router's 2.4 GHz signal from the next room. My phone's wifi tethering supports only 2.4 GHz. The phone can be right next to my laptop and register weak signal with about 1 Mbps download speed and 4 Mbps upload. My laptop worked well on 2.4 GHz wifi with the rtl8821ce driver provided by tomaspinho, so I know it's not a hardware issue.

I'm using rtl8723de and build the latest rtw88 driver. When I set ant_sel=2 in modprobe.d directory, I got this from dmesg:
rtw_8723de: unknown parameter 'ant_sel' ignored

OS: Artix Linux
Kernel: 5.7.6-artix1-1

Thank You.

basically i have tried all your instructions but still not working, i could see there is no network controller available in the list above. I am using virtualBox but wifi works fine in laptop. I tried different linux OS still same issue persist. watched too many videos and books but couldn't find solution. most of the users using your repository. i think this is the best platform where i can expect to get the resolution.

PLEASE HELP TO SORT THIS OUT!!

Not sure if its an issue on your the driver's or not. Had no issues during previous updates. After updating to 5.4.88-1-lts (on Arch) and reinstalling the drivers as usual, wifi went down. lspci and modprobe show module loaded correctly.
Steps taken: updated kernel, rebooted, reinstalled drivers, rebooted
Downgrading to 5.4.87-1-lts solved the issue.

Im just wondering if you support freebsd in future?
