Reboot EnGenius gateway when we notice the ethernet is down (from wireless side, but would work ethernet side if ethernet is not the problem) Cron Monitor Script DDWRT

#
# We had a problem wiht EnGenius access point loosing ethernet link, but was accessable
# from wireless side. we ran this script on one of the DDWRT routers on wireless side
# specifing an address on the other side of the ethernet link.  Put this in a cron
# and specify an IP address on the other side, and if it is not accessable, check
# that the EnGenius access point is accessable, if so reboot it via the telnet CLI.
#
# we ran this every 15 min via cron on ddwrt on wireless side of access point
#
# put username, password and address of EnGenius gateway below.
#
# remove these comments if storing script in EEPROM
