我有问题。我在 Ubuntu 21.10（内核 5.13.0.19-generic）上没有以太网和 wifi。主板：MSI PRO Z690-A WI-FI（英特尔® I225-V 2.5Gbps LAN，英特尔® Wi-Fi 6 模块）
我执行了命令：
lspci -nnk | grep 0280 -A3
结果：
Network controller [0280]: Intel Corporation Device [8086:7af0] (rev 11) DeviceName: Onboard - Ethernet Subsystem: Intel Corporation Device [8086:0074] Kernel modules: iwlwifi
命令：
sudo dmesg | grep iwl
