I could probably buy 2 or 3 of the most expensive managed switches with the coin I would have made without these issues in the last 2 months.. I have narrowed it down to this same thing: https://www.reddit.com/r/EtherMining/comments/6xkau1/simplemining_os_with_5_or_6_gtx_1070s_makes/

Network storms!? Tried different OSs, 4 different routers & 3 (albeit netgear) switches. I'm bypassing the switch completely to see if that is in fact the issue & if so after praising the Lord I'll get a Cisco.

Someone said a managed switch with spanning tree functionality could prevent network storms?
