Larry passed away a few months ago, so this repo is no longer maintained.
Doesn't the rtw89 driver in kernel 6.11 work for you?

This error appeared on Kali Linux kernel 6.11.2. Is there a solution?
It works flawlessly on kernel versions 6.8.11 and 6.10.11, but something broke after the release of 6.11.2.

Hi @iiivwviii,

There are two solution available for you.

1. Use the built-in rtw89 in your kernel which is even newer than the one here.
2. Use my rtw89 driver which is backported from kernel 6.13.

[iiivwviii]

unfortunately, these methods do not help (
Yes, all drivers are installed correctly, there are no errors during the installation process, but after restarting the PC, the Internet still works unstable, it may appear for a while, and then disappears again. There is a wi-fi connection, and when you try to execute a ping command to any site, there are long delays (1000ms) and severe packet loss, although there is a connection. Something is not working as it should.
Any idea why this might be?

@iiivwviii
Is your chip a RTL8852BE, too? Is there any error message in your dmesg? Could you post the full dmesg?
btw, the rtw89 driver here will work on kernel 6.11 if this patch is applied.

dmesg.txt
Yes, my chip is RTL8852BE.
Network controller: Realtek Semiconductor Co., Ltd. RTL8852BE PCIe 802.11ax Wireless Network Controller
Everything seems to be fine in dmesg. There are no errors related to rtw89.
patch for mac80211.c did not help me.

I tested my rtw89 driver on Kali LiveCD 2024.4 and no problem found, so...no idea what is wrong.

@a5a5aa555oo Thank you for your help!
I tried to reinstall the system completely, but the problem remains(.
Both the built-in kernel and your driver refuse to work((.
I guess I'll just have to change the adapter.

@iiivwviii
I am curious about what is the signal strength shown in wavemon?
Did you ever try the older Kali LiveCD which has kernel 6.8 or 6.10? does your 8852BE work fine in these older release?

[iiivwviii]

@a5a5aa555oo
I'm currently using version 6.8.11. Everything is working flawlessly.


wavemon in the kernel 6.8.11:

It looks like your 8852BE card is not broken, maybe you can email [email protected] to ask Realtek engineers for help as mentioned in README.md, that is the right place for you. Good luck!

@a5a5aa555oo Thanks for the help! I'll try to turn to [email protected].
