Something like that

#!/bin/sh

# Common vars
CHECK_IP="8.8.8.8"
PING_MAX_RETRIES=4

fails_counter=0

# Main loop
while [ true ]; do
	if [ $fails_counter -eq $PING_MAX_RETRIES ]; then
		reboot
	fi
	fails_counter=0
	sleep 60
	while [ $fails_counter -lt $PING_MAX_RETRIES ]; do
		if /bin/ping -c 1 $CHECK_IP >/dev/null 2>&1
		then
			break
		fi
		fails_counter=$((fails_counter+1))
	done
done
