rtw89_8852ce: WLAN does not properly work with 2.4 GHz networks
Last modified: 2023-11-07 18:40:14 UTC
User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/116.0 Build Identifier: WLAN-adapter: Realtech 8852ce The OS can sometimes detect 2.4 Ghz networks but cannot connect to them. 5 GHz works fine. Reproducible: Always Steps to Reproduce: Try to connect to a 2.4 Ghz Network. Actual Results: Will fail to connect Expected Results: Should connect. I am using a HP EliteBook 865 G10 Laptop (AMD Ryzen 7 7840U) Desktop environment: KDE Plasma I have tried to connect to different access points using different software tools.

(In reply to Daniel Rüpplein from comment #2) > Created attachment 869218 [details] > Information requested by Andreas Stieger > > Information requested by Andreas Stieger > hwinfo --netcard > hwinfo --wlan > dmesg ----- OK, while I was getting the information, I somehow successfully connected to a 2.4 GHz Netzwork but got disconnected like 3 seconds later and then could not reconnect. I am getting automatically reconnected to a 5 GHz Network (was connected to it before).

I do not have an 8852ce, but several others of the Wifi 6 chips work fine on the 2.4 GHz band. Pleae run the following command and post the results. Indicate the APs that you have tried: sudo iw dev wlp1s0 scan | egrep "SSID|freq|signal" If the device is busy, try again as that means your network control program is running a scan.

Hello, I tried the command several times. All 2.4 GHz netzworks appear and disappear seemingly at random (all at once). When it shows the 2.4 GHz networks it outputs: freq: 2437 signal: -24.00 dBm SSID: 'SSID 1' //This AP is right next to me. * SSID List * center freq segment 1: 8 * center freq segment 2: 0 freq: 2437 signal: -62.00 dBm SSID: 'SSID 2' //This AP is a bit further away. The 2.4 GHz networks work fine on Windows 10 btw.
I wanted to see the entire list. APs should not disappear, etc. Run the command sudo mv /usr/libexec/gsd-rfkill /usr/libexec/gsd-rfkill.save > scan0.txt sudo mv /usr/libexec/gsd-rfkill /usr/libexec/gsd-rfkill.save > scan1.txt sudo mv /usr/libexec/gsd-rfkill /usr/libexec/gsd-rfkill.save > scan2.txt Attach all 2 scanX.txt files.

"gsd-rfkill" does not exitst on my machine. rfkill itself is installed. Meanwhile I will attach the full list of the wifi-scan.

The only 2.4 GHz APs in range are freq: 2427 signal: -48.00 dBm SSID: DAN210 24 * SSID List * center freq segment 1: 6 * center freq segment 2: 0 freq: 2437 signal: -36.00 dBm SSID: Dan Thum * center freq segment 1: 0 * center freq segment 2: 0 The units with signal of -76 or lower would never make a stable connection. I expect that your 5 GHz connection is freq: 5300 signal: -57.00 dBm SSID: DAN210 I wonder if your user-space code is having a problem with the space in the SSIDs for the 2.4 APs. Given the name, I suspect that you control them. Please change "DAN210 24" to "DAN210_24" for a test. Your environment is very quiet. An "iw scan" for me shows 20 entries - 11 2.4.
Seemed to be a kernel-issue. Now running version 6.5.9-1. Now detects 2.4 Ghz networks reliably and stays connected. Sorry for the long wait.
