That is one way of doing it, but it gives a lot
more information than I want. It tell me the
Internet is working. I am not testing that.
I only want to know if the device is connected to the
gateway and the gateway is up.
So, ping the gateway?

I am setting up my iptables so it is universal. This
is only one of about 15 parameters I read from the
system.
Define "connected to". If by mean "accessible" then a ping or may
do. That is assuming the gateway
is configured to respond to pings. "Connected" usually means a connection is
established. As in an
ssh session.
