Auto on off for OSX airport

This works well for me on a mac mini G4. Substitute 192 for whatever is valid for you. Play with the delays to see what works best.

Also restart your wireless router everyday :) I don't know why this helps.

#!/bin/csh

set n = 0

set t = 120

while ( `/Users/me/helperanet` != 192 )

echo $n

networksetup -setairportpower off

sleep 3

networksetup -setairportpower on

sleep 6

@ n = $n + 1

end

with helperanet being

#!/bin/csh

set stra =( `networksetup -getinfo airport | grep -i ip | grep -i 192 | awk 'BEGIN {RS="."} /192/ {print $3}'` )

echo $stra
