# Conigure a "spare router" in a known-good state.
# This script configures the factory default settings of OpenWrt
# to make it easy to swap it in when a new router is needed.
# It also displays important configuration information when complete.
# You can print out those lines and tape them to the router so
# the next person will know how to access the router in the future.
# The format is:
#
# Configured: YYYY-MMM-DD
# Device: Belkin RT3200
# OpenWrt: 22.03.5 r20134-5f15225c1e
# LAN: 192.168.253.1
# User: root
# Login PW: SpareRouter
# WiFi SSID: SpareRouter
# WiFi PW: none
# The default settings of the script are generic, but the router will work.
# You could make a copy of this script, customize it to your needs,
# then use the "To run this script" procedure (below).
#
# ***** To run this script *****
#
# Flash the router with factory firmware. Then SSH in and execute these statements.
# You should do this over a wired connection because some of these changes
# can reset the wireless network.
#
# ssh root@192.168.1.1
# cd /tmp
# cat > config.sh
# [paste in the contents of this file, then hit ^D]
# sh config.sh
# Presto! (You should reboot the router when this completes.)
