我运行的是 Ubuntu 22.10，带有 Intel Wifi AX210 芯片。这是全新安装的，我整天都在使用 Wifi，直到它突然停止工作，我在 Wifi 符号应该出现的位置看到一个问号。互联网肯定可以正常工作，我的机器出了问题。
以下是我尝试过的解决方案中各种命令的输出

看起来问题可能出在这里：
Direct firmware load for iwlwifi-ty-a0-gf-a0-72.ucode failed with error -2
[ 4.052106] iwlwifi 0000:06:00.0: api flags index 2 larger than supported by driver
环顾四周，我看到了添加以下内容的建议/etc/modprobe.d/iwl.conf：
options iwlwifi 11n_disable=1 swcrypto=0 bt_coex_active=0 power_save=0
options iwlmvm power_scheme=1
options iwlwifi d0i3_disable=1
options iwlwifi uapsd_disable=1
options iwlwifi lar_disable=1
就我而言，这没有帮助。实际上，我没有 iwl.conf，而是自己创建的。我已经有一个 iwlwifi.conf，我也尝试在那里添加这些参数，但无济于事。
该文件的内容以前是：
remove iwlwifi \
(/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) \
&& /sbin/modprobe -r mac 80211
当我尝试将参数放入该文件时，我将它们添加到内容之前。
当我对其中一个配置进行更改时，我当然会重新启动。
