This affects both Linux Mint and a live Ubuntu environment, pointing to a kernel or driver- level incompatibility. **[Core Problem]** The connection drops every few minutes. The kernel log confirms this is not a signal loss, but a forced roam between mesh nodes initiated by a "deauthenticating by local choice (Reason: 3=DEAUTH_LEAVING)" event. The iwlwifi driver does not handle this handoff seamlessly, resulting in a full disconnection. **[Hardware & Network Environment]** * **Wi-Fi Card:** Intel Corporation Wi-Fi 6E AX211 160MHz * **Mesh System:** TP-Link Deco M9 Plus * **Mode:** Access Point (AP) mode **[Critical Test Results]** * **Hardware Confirmed Working:** The laptop is 100% stable on a non-mesh mobile hotspot. * **Mesh Features Disabled:** The issue persists even after disabling Fast Roaming, Beamforming, and separating the 2.4/5GHz bands in the Deco app. * **Guest Network Fails:** The instability also occurs on the Deco's isolated Guest Network. This isolates the fault to the Deco's fundamental (non-optional) node-steering logic and its incompatibility with the iwlwifi driver's handling of these specific deauthentication commands. --- ProblemType: Bug ApportVersion: 2.28.1-0ubuntu3.8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: veirvigour 1511 F.... pipewire veirvigour 1513 F.... wireplumber /dev/snd/seq: veirvigour 1511 F.... pipewire CRDA: N/A CasperMD5CheckResult: pass CurrentDesktop: X-Cinnamon DistroRelease: Linux Mint 22.2 InstallationDate: Installed on 2025-09-02 (8 days ago) InstallationMedia: Linux Mint 22.1 "Xia" - Release amd64 20250110 MachineType: HP HP ZBook Firefly 14 inch G9 Mobile Workstation PC Package: linux (not installed) ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-6.8.0-79-generic root=UUID=b8692ffd-5fa1-42a4-a981-3987303b21c6 ro quiet splash ProcVersionSignature: Ubuntu 6.8.0-79.79-generic 6.8.12 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running, or not running as session daemon.
