apport information ** Tags added: apport-collected questing wayland-session
** Description changed: 1) The release of Ubuntu Kubuntu 25.10 Questing Quokka - Linux Kernel 6.17.0-6 (bug may affected since 6.17.0-5 but not sure.) 2) The version of package you are using linux-firmware 20250901.git993ff19b-0ubuntu1.2 * It looks like similar issue reported at #2127965 ( https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/2127965 ) but the proposed version of linux-firmware (~1.3) by that bug also affected. 3) What expected to happen - Scan, Connect and Disconnect available in higher channels such as 144, 149 at 5GHz (Wi-Fi 5/6) - Scan, Connect and Disconnect available in 6GHz (Wi-Fi 6e/7) - the country code applied in phy#0 in `iw reg get` should be KR / US or other country codes that supports the right channels in Korea. 4) What happened instead - Scan, Connect and Disconnect only available in lower channels of 5GHz and all channels of 2.4GHz - the country code applied in phy#0 in `iw reg get` is 00-UNSET, which only supports very common channels, and cannot change by `sudo iw set {country_code}`. 5) Important Backgrounds - Tested in South Korea, which country allows higher channels of 5GHz and 6GHz. See Wikipedia ( https://en.wikipedia.org/wiki/List_of_WLAN_channels ) for more details. - It may be also related to kernel images / modules package because : using **6.16.12-061612-generic_6.16.12.202510121336** kernel from mainline does not affected by this bug. (`US` country code applied in this version by default) - In Info Center of Kubuntu, at PCI section, it seems like I am using WCN785x series now. ``` c2:00.0 Network controller: Qualcomm Technologies, Inc WCN785x Wi-Fi 7(802.11be) 320MHz 2x2 [FastConnect 7800] (rev 01) Subsystem: Lenovo Device e0e6 Flags: bus master, fast devsel, latency 0, IRQ 139, IOMMU group 15 Memory at b0600000 (64-bit, non-prefetchable) [size=2M] Capabilities: <access denied> Kernel driver in use: ath12k_pci Kernel modules: ath12k ``` 6) Other System Information ThinkPad T14s Gen 6 AMD with AMD RYZEN AI 7 PRO 360 (Radeon 880M) - 32GB RAM (Micron Technology), 512GB PCIe 4.0 SSD (Kioxia) - Secure Boot disabled, dual-boot with Windows 11 25H2 - Upgraded from Kubuntu 25.04, with mainline kernel version 6.16.12. - Before upgrading Kubuntu, I've installed mainline kernel because ath12k - driver in the stable version of kernel make freezing system by - disconnect Wi-Fi.
