I have 10 mining rigs on my mining room. One of them has internet problem.
I see there is internet network and i can surf the web without any problem. But the miner software shows no internet connection from time to time.

I use Windows 10 x64 Pro Lite and SRB Miner 1.65
The rig has 11500 h/s with 12 x RX570 4GB. My avarage hashrate is 8100 h/s because of internet connection problem.
The other rigs has no problem. Only this one. I installed a fresh Windows but no solution.
