    Hello, I have been using the Antminer S9 for a long time, and it's very pleasant to work with you, but today I had a problem when I want to go into the configuration configurations. The error 404 - Not Found, could you help solve this problem in advance thanks

    After the installation of the latest upgrade on my D3 miners. Some of them started showing very odd results:

    5840 +5644 should  be 11484 but not 17200. Strange math from Bitmain. Tired of struggling with this faulty production.

    Hello to all...

    I have a problem with S7 and S9 too

    The miner works without hash rate and all on miner status look OK. Have anybody idea where can be the problem or whot can I do for detect. Thanks

    The hash rate of S7 is normal around 5,4 TH/s (54 ASIC on each board) Now is hr only around 2 TH/s.

    Hi Radim Suchopar,

    Your discarding 90% of the shares your given to solve, this could be a connection issue or could be something wit the miner. Not sure how to fix it if its the miner, if its internet- check all the ports in your router
