obcas sa stane, ze vytuhne wifi(radio) vrstva

na to mame v zalohe nasledujuci skriptik

je potrebne mat nainstalovanu len utilitu wifimon
a nastavit ktory interface sledovat (wlan0) a aku SUBSIET
(napr. 10.176.1.xxx)

Skript si zisti, ci je asociovany aspon jeden klient, inak urobi reset alebo inu lubovolnu cinnost

skript doporucujeme volat raz za 5 minut z crontabu

#!/bin/bash

#
# PING WATCHDOG UTILITY
# 1.00 (C) mgx info at skfree dot sk

INTERFACE="wlan0"
CHECK_IP="10.176.1"
SYSCONFIG="/var/log/syslog"

WIFIMON=`which wifimon`
REBOOT=`which reboot`
# =========setting ====================
result=`$WIFIMON -$INTERFACE -once | grep $CHECK_IP`

if [ -z "$result" ]; then
echo "SYSTEM IS DEAD"
echo "Wificard $INTERFACE crashed -> restarting [WATCHDOG]"
$REBOOT
else
echo "SYSTEM IS ALIVE"
fi
#echo $result
exit 0;
