Editor to share with you how OpenWRT enables the working mode switch and networking. I hope you will get something after reading this article. Let's discuss it together.

The main configuration rc.local script is as follows:

Read_gpio () {(echo $1 > / sys/class/gpio/export) > & / dev/null (echo "in" > / sys/class/gpio/gpio$1/direction) > & / dev/null return `cat / sys/class/gpio/gpio$1/ value`;} read_gpio 19 / cat / sys/class/gpio/gpio$1/ value` 01001) v = "hotspot";; 11000) v = "4th";; *) v = "error";; esaccp / etc/config/$v/* / etc/config/logger working mode: $vexit 0

The principle is to boot and automatically copy the configuration files under / etc/config/. You don't need all the configuration files, just firewall, network and wireless. Name it according to the working mode and create three directories:

Mkdir / etc/config/apmkdir / etc/config/repeatermkdir / etc/config/hotspot

Later, we will write the configuration file and put it in these directories. Take ap as an example. In this mode, the network port is used to do WAN, and wireless LAN,WAN is done. Take ADSL access as an example, and other cases are self-adaptable:

Uci set wireless.@wifi-device [0] .password = 0bot UCI set wireless.@wifi-iface [0] .ssid='umu618.com';uci set wireless.@wifi-iface [0] .encryption='psk2+ccmp';uci set wireless.@wifi-iface [0] .key='WiFi password'; uci commit wireless Wifiuci delete network.lan.ifnameuci delete network.lan.typeuci add network interfaceuci rename network.@interface [- 1] = 'wan'uci set network.@interface [- 1] .ifname =' eth2'uci set network.@interface [- 1]. _ orig_ifname='eth2'uci set network.@interface [- 1]. _ orig_bridge='false'uci set network.@interface [- 1] .proto = 'pppoe'uci set network.@interface [- 1] .username =' broadband account 'uci set network.@interface [ -1] .password = 'broadband password' uci commit networkcp / etc/config/firewall / etc/config/ap/cp / etc/config/network / etc/config/ap/cp / etc/config/wireless / etc/config/ap/

Let's talk about repeater, network port to do LAN, wireless to do an AP Client and an AP. Note that the following command is based on the initialized configuration file. Please back up and restore in advance. Do not continue the configuration directly after configuring the previous ap mode. There may be problems.
