1. Twice in the last two weeks the S9 just lost connection to slushpool. Internet connection is fine, the S9 is functioning correctly, all the boards are ok, the ethernet connection to LAN is obviously fine since I can access it, it just doesn't connect to slushpool. First time that was for 2 days before I noticed, so it doesn't correct itself.

2. ... and could be related to 1 - when I rebooted, both times it took more than 2 hours to start hashing. Before that the Miner Status was showing blank - no boards, no stats, nothing. No BMMiner version on the system page either. After 2+ hours it started hashing.

So - what, other than a reboot, can I do with (1) - and why does (2) happen when I see that others see it hashing 20 min after reboot?

Thanks.
