1 前言
一个问题，一篇文章，一出故事。
笔者最近给家里的PC安装了一张无线网卡，网卡安装使用如下命令查看日志，
dmesg
可见如下错误提示，
[ 7.470949] Intel(R) Wireless WiFi driver for Linux [ 7.789839] iwlwifi 0000:03:00.0: firmware: failed to load iwlwifi-ty-a0-gf-a0-72.ucode (-2) [ 7.789868] firmware_class: See https://wiki.debian.org/Firmware for information about missing firmware [ 7.789905] iwlwifi 0000:03:00.0: firmware: failed to load iwlwifi-ty-a0-gf-a0-72.ucode (-2) [ 7.789920] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-ty-a0-gf-a0-72.ucode failed with error -2 [ 7.789973] iwlwifi 0000:03:00.0: firmware: failed to load iwlwifi-ty-a0-gf-a0-71.ucode (-2) [ 7.790010] iwlwifi 0000:03:00.0: firmware: failed to load iwlwifi-ty-a0-gf-a0-71.ucode (-2) [ 7.790025] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-ty-a0-gf-a0-71.ucode failed with error -2 [ 7.790058] iwlwifi 0000:03:00.0: firmware: failed to load iwlwifi-ty-a0-gf-a0-70.ucode (-2) [ 7.790098] iwlwifi 0000:03:00.0: firmware: failed to load iwlwifi-ty-a0-gf-a0-70.ucode (-2) [ 7.790113] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-ty-a0-gf-a0-70.ucode failed with error -2 [ 7.790144] iwlwifi 0000:03:00.0: firmware: failed to load iwlwifi-ty-a0-gf-a0-69.ucode (-2) [ 7.790181] iwlwifi 0000:03:00.0: firmware: failed to load iwlwifi-ty-a0-gf-a0-69.ucode (-2) [ 7.790196] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-ty-a0-gf-a0-69.ucode failed with error -2 [ 7.790236] iwlwifi 0000:03:00.0: firmware: failed to load iwlwifi-ty-a0-gf-a0-68.ucode (-2) [ 7.790271] iwlwifi 0000:03:00.0: firmware: failed to load iwlwifi-ty-a0-gf-a0-68.ucode (-2) [ 7.790286] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-ty-a0-gf-a0-68.ucode failed with error -2 [ 7.790317] iwlwifi 0000:03:00.0: firmware: failed to load iwlwifi-ty-a0-gf-a0-67.ucode (-2) [ 7.790354] iwlwifi 0000:03:00.0: firmware: failed to load iwlwifi-ty-a0-gf-a0-67.ucode (-2) [ 7.790369] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-ty-a0-gf-a0-67.ucode failed with error -2 [ 7.854609] iwlwifi 0000:03:00.0: firmware: direct-loading firmware iwlwifi-ty-a0-gf-a0-66.ucode [ 7.854639] iwlwifi 0000:03:00.0: api flags index 2 larger than supported by driver [ 7.856167] iwlwifi 0000:03:00.0: TLV_FW_FSEQ_VERSION: FSEQ Version: 0.63.2.2 [ 7.887667] iwlwifi 0000:03:00.0: firmware: failed to load iwl-debug-yoyo.bin (-2) [ 7.887724] iwlwifi 0000:03:00.0: firmware: failed to load iwl-debug-yoyo.bin (-2) [ 7.887743] iwlwifi 0000:03:00.0: loaded firmware version 66.f1c864e0.0 ty-a0-gf-a0-66.ucode op_mode iwlmvm
2 最佳实践
2.1 确认无线设备的型号
lspci | grep -i network
可见如下显示，
03:00.0 Network controller: Intel Corporation Wi-Fi 6 AX210/AX211/AX411 160MHz (rev 1a)
2.2 下载最新固件解压并重新安装
wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/snapshot/linux-firmware-20230804.tar.gz tar -xf linux-firmware-20230804.tar.gz cd linux-firmware-20230804/ cp iwlwifi-ty-a0-gf-a0* /lib/firmware/
