OpenWrt MediaTek AP Router 1

1.1

Wireless configuration via UCI

Basic idea

There are already 2 ways to configure MTK wireless drivers.

1) Using iwpriv command. (eg: iwpriv ra0 set SSID=myrouter)

2) Edit the profile of the driver. (located at /etc/Wireless/chipname/chipname.dat)

rd

Here we introduce the 3 way, which is for the convenience of LuCI development. To use this feature, you should enable uci2dat first. You can find this application at: Menuconfig -> Ralink Properties -> Applications -> uci2dat

Then you can configure MTK wireless drivers via uci commands, like this:

uci set wireless.chipname.option1=value1 uci set wireless.chipname.option2=value2 ……

uci commit wifi down wifi up

1.2 Examples

In your script, you should replace “chipname” with the right name of your wireless chip, (like mt7620, mt7612, mt7602, mt7610 etc).

1.2.1

SSID

This is a little tricky, read the example carefully. uci set wireless.@wifi-iface[n].ssid=newssid

N is the index of the interface you want to change. You can check the interface index by : uci show wireless

You may see something like this:

If you want to change “OpenWrt-mt7620” to “MyNew7620”, you should call:

uci set wireless.@wifi-iface[1].ssid=MyNew7620 # “1” is the index of “OpenWrt-mt7620”

1.2.2

Encryption

Read the example in “SSID” section first, then you can: uci set wireless.@wifi-iface[n].encryption=x x could be: x psk-mixed psk2 psk wpa-mixed wpa2 encryption WPAPSKWPA2PSK WPA2PSK WPAPSK WPAWPA2 WPA2 ? 2014 - 2015 MediaTek Inc.
