Are you on WiFi or Ethernet?
They are all Ethernet wired, allways have been.
[Not the best idea. It is better to use Kryptex for a beginner or Nicehash for a slightly more experienced user. In both cases, auto-exchange is possible.
I know them both. However I'm not looking for BTC payout.
BTW, i tried mining a cpu algo today and the same thing happened with zergpool. Other pools seem to work flawlessly.
