** Description changed: Hello Ubuntu Kernel Team, I am reporting a reproducible Wi-Fi instability issue with the Intel AX211 card on a TP-Link Deco mesh network. 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. + 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. + RelatedPackageVersions: + linux-restricted-modules-6.8.0-79-generic N/A + linux-backports-modules-6.8.0-79-generic N/A + linux-firmware 20240318.git3b128b60-0ubuntu2.17 + Tags: zara + Uname: Linux 6.8.0-79-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: N/A + _MarkForUpload: True + dmi.bios.date: 04/10/2025 + dmi.bios.release: 15.0 + dmi.bios.vendor: HP + dmi.bios.version: U70 Ver. 01.15.00 + dmi.board.name: 896D + dmi.board.vendor: HP + dmi.board.version: KBC Version 02.76.00 + dmi.chassis.type: 10 + dmi.chassis.vendor: HP + dmi.ec.firmware.release: 2.118 + dmi.modalias: dmi:bvnHP:bvrU70Ver.01.15.00:bd04/10/2025:br15.0:efr2.118:svnHP:pnHPZBookFirefly14inchG9MobileWorkstationPC:pvrSBKPF,SBKPFV2:rvnHP:rn896D:rvrKBCVersion02.76.00:cvnHP:ct10:cvr:sku735M0PA#UUF: + dmi.product.family: 103C_5336AN HP ZBook + dmi.product.name: HP ZBook Firefly 14 inch G9 Mobile Workstation PC + dmi.product.sku: 735M0PA#UUF + dmi.product.version: SBKPF,SBKPFV2 + dmi.sys.vendor: HP ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/2122280/+attachment/5908203/+files/AlsaInfo.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2122280 Title: iwlwifi: Intel AX211 disconnects and roams constantly on TP-Link Deco Mesh (AP Mode) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2122280/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
