# this script force router fonera to act as: 
# - repeater (of an external AP) on ath1, configured by the external AP dhcpd 
# and
# - Access Point on ath0 (configured here as 192.168.10.1/24) with SSID "fonera"
#
# The two subnet are then routed.
# You can arrange your fonera near a window (better if connected to an antenna or can-antenna)
# and let it gains a signal that will be repeated in your home by ath0.
# So you can associate your WiFi-interface to the AP builded on ath0
# eg.
#        iwconfig ethn essid fonera
#        ifconfig ethn 192.168.10.2 netmask 255.255.255.0 up
#        route del default
#        route add default gw 192.168.10.1
#
# and browse the internet by the external AP.
# Powering off fonera will be return in standard mode !
# This script must be written in /etc
