Here's one I used for checking my internet connection... perhaps you can 
modify it for your needs.  Someone on this list was kind enough to share it 
with me about a year ago, or so.  Cannot remember the name, unfortunately.

How to stay connectd to internet:

  #!/bin/bash
  #
  # Script to check if ADSL is disconnected & try reconnecting
  #
  result=$(cinternet -i dsl0 -s | grep disconnect)
 #Checks the status of device dsl0 for the word 'disconnect' and stores the
 #result in a variable called 'result'
  if [ -n "$result" ]
 #Test to see if the value is not NULL
  then
 #OK the interface is down
  cinternet -i dsl0 -A
 #Start the interface.
  sleep 10
  else
 #The interface is up - Just exit
  exit 0
  fi
