+# NOTE! THIS IS A MODIFIED VERSION OF THE ORIGINAL PROGRAM
+# WRITTEN BY KEVIN REED.  TO GET THE ORIGINAL PROGRAM SEE
+# THE URL BELOW:
+#
+# A Project of TNET Services, Inc
+#
+# Title:     WiFi_Check
+# Author:    Kevin Reed (Dweeber)
+#            dweeber.dweebs@gmail.com

+#            https://github.com/dweeber/WiFi_Check
+#
+# Purpose:
+#
+# Script checks to see if WiFi has a network IP and if not
+# restart WiFi
+#
+# Uses a lock file which prevents the script from running more
+# than one at a time.  If lockfile is old, it removes it
+#
+# Instructions:
+#
+# o Install where you want to run it from like /usr/local/bin
+# o chmod 0755 /usr/local/bin/WiFi_Check
+# o Add to crontab
+#
+# Run Every 5 mins - Seems like ever min is over kill unless
+# this is a very common problem.  If once a min change */5 to *
+# once every 2 mins */5 to */2 ... 
+#
+# */5 * * * * /usr/local/bin/WiFi_Check
