[arm-allstar] Rpi 3 network issues

[Stanley Stanukinos]

Double check your configuration on the switch

If the configuration is wrong it will be dropping packets. That will cause the issue you are experiencing.

I have two controllers at that site and they don't go up and down together; sometimes both are up, sometimes only one.  At first I thought it was the wireless link (it's a mountain-top repeater) but I can access other things on the remote network just fine.

It's as though it's an issue that only crops up when going across the wireless bridge, and only on the raspberry pis.
