OpenWrt路由器通过CLI命令修改Wifi无线设置

Posted on 2024-10-09 In linux

我爸菜园子怕别人偷菜让我帮忙给装一个监控，这样有人进入就会报警，并且实时可以看到菜园子情况。平房没有网络我打算给那里放一个CPE，插一张副卡用来给监控提供网络。手头有一个之前帮忙测评用的工程版CPE，想着物尽其用，设置了一下发现不能改变SSID，可能是工程版原因软件还不完善，也凑合着能用可是特别挑战我的强迫症。由于我知道这个CPE的固件是通过OpenWrt魔改过来的，于是我尝试能不能通过命令的方式来改一下SSID，结果还真做到了。这里简单记录一下步骤：

首先打开NRadio的ssh开关，浏览器打开：

然后使用uci命令来修改OpenWrt的网络设置。可以先用uci show network 和uci show wireless来看下当前设置：

从中可以看到我们比较关心的是wireless.wlan0.ssid=NRadio-0CBE-2.4G 和wireless.wlan1.ssid=NRadio-0CBE这两项，这和网页里看到的内容是相同的，但是网页配置端由于未知bug修改不了。我在这里尝试用uci命令修改：

1	uci set wireless.wlan0.ssid=NRadio-0CBE-2.4Guci set wireless.wlan1.ssid=NRadio-0CBE

然后保存更改：

1 2	uci commit wireless uci commit network

重启后生效。

1	/etc/init.d/network restart
