2.4 GHz Wi-Fi 關聯超時

  • February 6, 2022

連接到 2.4 GHz 接入點在某個更新點中斷(不記得確切的位置,無論是核心還是 iw 更新)。當連接關聯超時並且嘗試幾次後整個連接過程被取消。5 GHz 接入點仍按預期正常工作。

我嘗試了幾種不同的發行版(Fedora 32、Pop!_OS 20.04、Ubuntu 20.04),它們都有相同的問題(我在實時環境中執行它們)。

唯一有效的發行版是 Elementary OS 5.1。我認為這是因為它基於具有較舊核心和 iw(linux 5.3.0、iw 4.14)的 Ubuntu 18.04。下面是我嘗試連接到 2.4 GHz 接入點時

的規格和日誌。dmesg

Laptop: Thinkpad T540p

通過申請options iwlwifi i11n_disable=1解決/etc/modprobe.d/iwlwifi.conf

在較新的版本中,該選項被重命名為11n_disable
