I have a similar issue. The miner boots up, and the chaser lights on the both boards run - but it never connects to the network. I think the beaglebone shorted out when I had a lightning strike.
I tried everything and can't get it to work. It did start running for about 3 hours the other day and then stopped.....very frustrating.
I am hoping I can purchase a new beaglebone from CoinTerra and install it myself.
