Wifi connection failing due to long "AP is in CSA process, reject auth"

Hi there

Following the upgrade to Fedora 40 Silverblue kernel 6.8.8-300.fc40.x86_64, I started having issues connecting to my wifi (2.4G band) using my motherboard wifi

Intel Corporation Wi-Fi 6E(802.11ax) AX210/AX1675* 2x2 [Typhoon Peak] (rev 1a)

The AP shows up with strong signal, I can initiate the connect, but then I get a network error and when looking into the logs with dmesg -w I get:

AP is in CSA process, reject auth

followed by it defaulting to my 5G band (which is pretty weak).

It appears to get (temporarily) resolved by choosing a fixed channel in my router

ASUS GT-AX6000 running stock firmware

From what I can find online (which was surprisingly little), the issue appears to similar to the one in this reddit post about kernel 6.7 in Arch and this kernel discussion:

This appears to indicate it should be resolved, but given my current situation I am not sure.

However, I do not know if it is just not implemented in the current Fedora kernel (not sure where to check this) or this is a separate issue.

I just know that I have spent quite some time looking at both the router and my PC logs to get to this point and am now stuck :slight_smile: Thanks in advance for any support you could provide.

  1. PS: Not sure this is relevant, but I dual boot Win11 on the system and here all appears to be fine, so doubt it is a hardware issue. ↩︎
