Scripts for OpenWrt on TP-Link TL-MR3020 to change network configs using 3-position sliding switch. Configuration changes by UCI/LuCI overwrites the symbolic links used by original scripts. This version copies the scripts instead of using symbolic links. Added script attached to WPS button, to commit the updated config to the current config (3g,…

# Configuration changes by UCI/LuCI overwrites the symbolic links used by original scripts.
# This version copies the scripts instead of using symbolic links.
# Added script attached to WPS button, to commit the updated config to the current config (3g, ap or wisp) subfolder. 

# Instructions:
# 1. Copy all project files into /tmp, e.g. using SCP
# 2. Open a terminal session to the router
# 3. Run the commands below


#Prep files and sort them into appropriate folders
cd /tmp
