Because the Ethernet connection isn't always reliable.

I've had problems with one of my Pis not coming online when it boots up. 
Opinions seem to vary as why the Ethernet connection doesn't come up. In 
the house it is fine, but when it is out in the garden, it is less than 
evens as to whether or not it work, some days it just won't play.  Today 
I put it on WiFi (with the Ethernet unplugged), so we'll see what that 
does over the coming weeks.

I've tried setting up a cron job that runs once a minute that sends a 
single ping to the router, but that won't always wake the Ethernet 
connection up.
