英特尔无线 AC 9462 无法与 18.04 LTS 配合使用

所以我们又来了。在干净的 Ubuntu 18.04 LTS 安装中又出现了 Wi-Fi 问题。

dmesg | grep iwl

给了我这个：

lspci并且由于某种原因，网络控制器被列为而02f0不是英特尔双频无线 9462：

00:14.3 Network controller: Intel Corporation Device 02f0

我解决了。以下是按顺序在终端中输入的命令。确保您有以太网或一些外部 WiFi 适配器来访问互联网。我使用了用于黑客攻击的 USB WiFi 适配器。-

sudo apt update
sudo apt install git build-essential
git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
cd backport-iwlwifi/
make defconfig-iwlwifi-public
sed -i 's/CPTCFG_IWLMVM_VENDOR_CMDS=y/# CPTCFG_IWLMVM_VENDOR_CMDS is not set/' .config
make -j4
sudo make install
sudo modprobe iwlwifi

现在还有其他选择，backports-iwlwifi-dkms在 Ubuntu 存储库中，如果该版本不够新，还有这个：https://launchpad.net/~canonical-hwe-team/+archive/ubuntu/backport-iwlwifi

dkms 包的优点是您不必在每次内核更新后重新安装反向移植。
