[MassonY]

System:

• OS: Nobara Linux 40
• Kernel version: 6.11.7-201.fsync.fc40.x8
• Gcc: 14.2.1 (for kernel build and available on system)
• DE: Gnome 46

Product:

• TP-Link TX50UH
• AX3000
• 8832cu chipset
• lsusb output: Bus 002 Device 002: ID 35bc:0101 Realtek 802.11ax WLAN Adapter

Reproduction steps:

• Install driver
• Edit the option and put my country code : rtw_country_code=FR
dkms status output: rtl8852cu/1.19.2.1, 6.11.7-201.fsync.fc40.x86_64, x86_64: installed

Result:

• The dongle is detected:
  • ifconfig output :

The dongle is capable on scanning and it displays visible network on the Gnome Wifi ui but it cannot connect.
using the last git version of the driver (with the patch for TX50UH) i have the following errors:
journalctl -S today | grep wlp3s0f0u1 | grep ERROR:

Good report. I have been just testing 5 GHz and 6 GHz so let me reconfigure and test 2.4 GHz. Hopefully I can duplicate the problem.

Reconfiguration complete. Here is my first test:

I will continue testing.

The test is with the current repo.

WiFi Router details:

Channel 1
Channel width: 20 MHz
WiFi 6
Distance from client: ~ 7 meters with 2 walls in between
WPA2

nov. 13 15:13:16 nobara-pc kernel: RTW: ERROR _connect_msg_hdlr(wlp3s0f0u1): assoc_AP_vendor gone!

Is your AP set to mixed security? If so, try resetting it to WPA2 and retry.

I am not seeing this line. This line could indicate an issue with the AP. Can you provide some details of the AP setup?

@morrownr

Thanks for your testing

Wifi router details:
2 cards (2.4ghz and 5ghz) with the same configuration for both of them

• WPA2 - AES
• band width: 20Mhz (2.4ghz) and 160mhz (5ghz)
• Wifi 6 compatible (802.11b, 802.11g, 802.11n, 802.11ax for 2.4ghz) and (802.11a, 802.11n, 802.11ac, 802.11ax) for 5ghz
• 2 meter away from the AP, 1 wall in between.

I do have another USB dongle : Archer T3U Plus and I'm using your repo https://github.com/morrownr/88x2bu-20210702 to make it work.

This one isnt able to use wifi6 (which my AP supports) but has a very good connection to my AP and the driver works flawlessly (thanks for that by the way)

I do have another USB dongle : Archer T3U Plus and I'm using your repo https://github.com/morrownr/88x2bu-20210702 to make it work.

I think that once you get to kernel 6.12, the performance of the rtl8822bu driver in rtw88 (in-kernel) will be good enough that you can drop the my repo. The patches over the last year have helped but the patches over the last 2 months really bring rtw88 up to speed.

My primary router is using the same settings as yours. Do you have any other WiFi 6 capable adapters that you can test?

I am not able to reproduce this.

[MassonY]

Sorry I don´t have any other Wifi 6 capable adapter that i can test.

But I forgot to mention that i tried connecting with non-wifi6 network (namely the hotspot from my phone, with and without password protection) and it had the same behavior.

@MassonY

Thanks for the follow up report. I am a little discouraged by the issues that have come up.

[morrownr]

I'm still not coming up with anything on this issue. Another tester posted #15 this morning and it seems it may be similar to your problem. You might want to take a look and even answer some of the questions I posted for your own situation.
