Can you try the test kernel from: https://kernel.ubuntu.com/~juergh/lp1927037/
Download and install linux-image and linux-modules. ** Description changed: + [Impact] + + PCIe cards based on ath9k chips are not recognized. + + [Test Case] + + Plug a ath9k based PCIe card into the PCIe slot of a CM4 IO board and: + $ ls /sys/class/net/wlan0 + ls: cannot access '/sys/class/net/wlan0': No such file or directory + + [Where Problems Could Occur] + + Buggy driver could result in crashes. + + [Original Description] + Expected behavior: Network adapter should be visible via `iw list`, `iwconfig`, and `ifconfig`. Actual behavior: Network adapter is visible in `lspci` and `lshw`, but not in `iw list`, `iwconfig`, or `ifconfig` Details: The Atheros network card is detected by the ath9k driver when installed into a machine with x86_64 architecture. When the same card is installed into a miniPCIe-to-PCIe adapter, then plugged into a Raspberry Pi CM4 IO breakout board, the network adapter can be seen via lspci and lshw but is not seen by iw, iwconfig, or ifconfig. lspci: ubuntu@ubuntu:~$ sudo lspci -v 00:00.0 PCI bridge: Broadcom Inc. and subsidiaries Device 2711 (rev 20) (prog-if 00 [Normal decode]) -
