s9 stops hashing at pool after awhile....

[fyoung55]

Hey,
I have an s9 that hashes great for a few hours (anywhwre from 3 - 8hrs), then the pool I'm at stops receiving.  Not just momentarily either, this last time it stopped for 3 hours (didn't check it for awhile...).  The gui on the s9 shows it's still hashing away just fine, and it shows all pools alive.  Once I reboot the machine, it hashes fine for awhile and then stops.  I use 3 mainstream pools (viabtc, slushpool, and Nicehash) and it doesn't hash on any of them for more than a few hours before conking out.

I'm using an APW3++ PSU on 220v, so power shouldn't be an issue.

Any thoughts?

Sounds like network connectivity issues. The miner GUI allows for some very basic troubleshooting. You should take advantage of that the next time you think it drops.

Some other things to check, what's the temp? Are you 110v or 220v?

did you try to use the short 6ft eth cable and not the long 50 foot old cable?

That would entail switching it with the one that works better.

if you switch it to the one that works use the psu from the one that works.

the unit unit you have is a 14tb from  dec 2017 it is only 2 month old.

what is you internet service?

and what are the 6ft and 50 cables plugged into the router?

 what is the router make and model?

do you have an ethernet switch?

We spoke in pm an old 50 ft eth cable can be the problem.

The cat 7 is on the way.

Thanks Phil I'll try all that, I posted this before all of the trouble shooting through pm we did.

Whelp... switching machines helped.  I kept PSUs with their respective machines, and the previously suspect S9 has run for 24 hours without a hiccup.  Seems like the ethernet cable/long run was the issue.  I knew "friends don't let friends use 120v"... now we need to add "friends don't let friends use old ass cat 5 on a long run"

Thanks for your help fellas... you especially phil!
