配置Wi-Fi同时工作在STA+AP模式

这篇文档介绍如何在Ubuntu下配置Wi-Fi同时工作在STA+AP模式。

准备工作

固件基于V2005版本,并将OTA升级到最新的版本。

开始配置

将wlan0配置为STA模式,将wlan1配置为AP模式。

添加wlan1

1
khadas@Khadas:~$ sudo iw phy phy0 interface add wlan1 type managed

验证

1、关闭以太网

1
khadas@Khadas:~$ sudo ifconfig eth0 down

2、wlan0是否能用于上网

尝试ping www.khadas.com:
