I am facing the same issue here Chipset / Adapter - Model: Qualcomm WCN785x — "FastConnect 7800" — WiFi 7 (802.11be), 320MHz, 2x2 - PCI ID: 17cb:1107, rev 01 - Board/module: Foxconn "High Band Simultaneous Wireless Network Adapter" (subsystem 105b:e0f7) - Motherboard: MSI MAG B850 TOMAHAWK MAX WIFI (MS-7E62) — this is the M.2 WiFi module on that board
Firmware - fw_version: 0x1108811c - fw_build_id: WLAN.HMT.1.1.c5-00284.1-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3 - fw_build_timestamp: 2025-05-17 00:21 - chip_id: 0x2, chip_family: 0x4, soc_id: 0x40170200 Driver - Linux kernel driver: ath12k_wifi7_pci / module ath12k_wifi7 - Kernel: 7.0.0-30-generic (Ubuntu 24.04.4 LTS) The bug to report Recurring kernel errors, happening multiple times per day, intermittently after regulatory-domain/country-code negotiation: ath12k_wifi7_pci 0000:04:00.0: Failed to set the requested Country regulatory setting ath12k_wifi7_pci 0000:04:00.0: Timeout while waiting for regulatory update Effect: when this fires, the 5GHz band becomes completely unusable — the card stops scanning/seeing any 5GHz networks at all (only 2.4GHz remains visible), even though the router and other devices see 5GHz fine. Physically unplugging and replugging the adapter forces a clean firmware reinit and temporarily resolves it until it recurs. ** Attachment added: "ath12k_journalctl_full.txt" https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/2130490/+attachment/5996462/+files/ath12k_journalctl_full.txt ** Changed in: linux-firmware (Ubuntu) Status: Expired => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2130490 Title: ath12k : DFS-UNSET disables some channels of 5GHz and 6GHz by default To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/2130490/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
