我已经在我的 ThinkPad x390 上安装了 Ubuntu 20.04，但无法让 Wifi 工作。
系统似乎看到了该设备
spci | grep -i net
00:14.3 Network controller: Intel Corporation Wireless-AC 9462
00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (6) I219-V
我已经安装了 backport-iwlwifi-dkms 并且 iwlwifi 已加载
lsmod | grep iwlwifi
iwlwifi 352256 1 iwlmvm

我尝试安装英特尔的 /lib/firmware 中的固件https://www.intel.com/content/www/us/en/support/articles/000005511/network-and-io/wireless-networking.html
我似乎无法让界面显示出来
iwconfig
lo no wireless extensions.
enp0s31f6 no wireless extensions.
enxa0cec8c81fd9 no wireless extensions.
我错过了什么？我找到了这篇文章在 Ubuntu 20.04 上使用 Intel Wireless-AC 9462 无法上网？但当我进入“附加驱动程序”选项卡时，什么都没显示。我猜是其他驱动程序？
