OpenWRT opkg 安装软件包时内核版本不匹配问题解决

问题描述

今天在软路由上安装无线网卡，网卡型号为AR5B125，网上找资料得到驱动包在kmod-ath9k中，一顿操作安装，报错kmod-ath9k found, but incompatible with the architectures configured。

固件版本 Openwrt Koolshare Router V2.37 r17471-8ed31dafdf
内核版本 5.4.108

软件包地址：https://downloads.openwrt.org/snapshots/targets/x86/64/packages/
需要内核版本：5.4.137

解决方案

匹配内核

如图在package目录中找到以kernel开头的ipk文件（类似内核补丁），下载并安装，然后重启；以5.4.137为例
