[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.
