[arm-allstar] Chasing Multiple Rpi Node Gremlins

I'm not sure what is going on in any of these problems, but, here are some
things to check:
Items 1 and 2: I suspect a configuration problem, likely in the rpt.conf
Item 3: The bandwidth required for nodes is quite small, as an example,
I'm typing this, browsing the web and have 3 nodes up and running right
now on my DSL, which is 6Mbps down / 768Kbps up...And, I've got plenty of
bandwidth to spare.
Does the Internet performance problem show up when the node is
transmitting?? If so, the transmitter RF is the place to look.
