lspci出于某种原因，其中的网络控制器被列为 02f0 而不是 Intel Dual Band Wireless 9462-

00:14.3 Network controller: Intel Corporation Device 02f0

Answer 1

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
