Dropbox does not connect on startup

I have issues with Dropbox on my laptop running arch linux. If the internet connection is lost, uppon
reconnection Dropobox fails to reconnect and its status stays forever to "Connecting". I wrote a script
that checks if there is connection to the internet and if so, it restarts the dropbox service if hung. It has
to be run on startup in the background.

#!/bin/bash

# While there is a connection, the script checks every 60 secs if 
# the dropbox status is "Dropbox isn't running" or "Connecting",
# and if so, it reconnects the service. Could start from .xinitrc.

while true; do
    ping -c 1 www.google.com 1>/dev/null 2>/dev/null
    if [ "$?" = 0 ]; then
        dropbox status | egrep 'isn|Connecting'>/dev/null
        if [ "$?" = 0 ]; then
            dropbox stop
            dropbox start
        fi
     fi
    sleep 2
done

To make this work you have to run the above script on startup. For instance, you could do the following:

• Put the above lines in a file called checkdropboxstatus.sh. 
• Put that file in you /home/yourusername/.config/autostart/ folder.
• Go to that folder and change the permissions to executable
  

  cd /home/yourusername/.config/autostart
  chmod +x checkdropbox.sh

Now dropbox shouldn't hung anymore.
