![搭载 Intel 9462 的 Ubuntu 20.04 没有 Wifi](https://linux22.com/image/935989/%E6%90%AD%E8%BD%BD%20Intel%209462%20%E7%9A%84%20Ubuntu%2020.04%20%E6%B2%A1%E6%9C%89%20Wifi.png)
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?
