Q: after i upgraded to maverick, my internet connection keeps dropping

I definitely think this is a Mavericks issue.  My iMac running Mavericks is the ONLY system in the house that drops the network randomly while all other systems never lose the network.  No idea how to resolve this, but here is the workaround I'm posting:

I've had the 'network drop' issue with my Airport Extreme for the last 2 months.  It reconnects when I pull the ethernet cable and plug it back in.  I've tried downgrading the AE firmware, resetting to factory, etc.  Nothing worked.  I finally threw in the towel and created a script that monitors my network connectivity and restarts my interface if it senses it has dropped:

 

##############

#!/bin/ksh

while true

do

  yup=`ping -c1 -t2 www.google.com|grep from`

  if [[ -n $yup ]]

     then echo "Internet is connected!"

  else

        ifconfig en0 down; ifconfig en0 up

        echo "Down at `date +%m%d%Y%H%M%S`">>./dropped.out

  fi

  sleep 5

clear

done

###############

 

I know its a workaround, but its saving me the headache of constantly pulling my cable and putting it back in!

 

Good luck!

mikengray's solution is the only thing that worked for me. I modified the script as 'ifconfig up/down' required root privilages so this uses the 'networksetup' command. This script seems to do a decent job at reconnecting after sleeping the laptop. Now I don't have to right-click disconnect/reconnect the WIFI every 5 minutes. Also this script keeps a log in the home folder of all the dropouts. Looking at the log for yesterday there are over 100 dropouts throughout the day.

Put this in a textfile 'keepalive-script' in your home folder and 'sudo chmod +x ~/keepalive-script' it in the terminal to make it executable on double-click. I moved mine to the desktop and run it when I log in, leaving it on in the corner of the screen...
