I agree, there is not much to mess with in the configuration of an S5. 

My miners are all on DHCP, running on a brand new Gigabit Broadband VPN Router with HP Procurve switches.  I recently upgraded my LAN in preparation for Comcast's new 2GB high speed internet service.  Yes, that's TWO GIGABIT INTERNET.  Its already out and I am just waiting for the installation that will bring fiber to my front door. 

I know you guys are trying your best to help me (for which i am very grateful; THANK YOU AGAIN for your time), but I have already tested and re-tested all of the obvious failure points.  I have pinged, trace rt,  and looked up every DNS & IP address from here to china. 

I have a BS in engineering and i have worked in IT for the past 25 years for a fortune 50 company.   Trust me when I say its not a power nor an internet issue.   Having said that, I must confess that I had an early 4th of july fireworks show in my bedroom awhile back when I connected the power to an S5 backwards. . . .      That's the reason for one of the bad Beaglebones.
