I used 4x1060 6GB, and ethminer on Linux 16 and overlock GPUs When i start script everythings works ok, but after some hours, everything look ok, i receive new jobs but my miner to making "Submitted and accepted."
I already switch internet from wifi to cable, and same situation
I think it can be 3 possible problems
2)Internet Provider(uploading issues)(i test internet speed and it was fast)
3)Linux GPU drivers(possible)
4)or Pool( i had others machines, and they are working ok with same pool)
Maybe smbd can advice how to find that problem
