My internet is very slow now that my 3 rigs are running. Rig 1 is 103Mhs, rig 2 is 92Mhs, rig 3 57Mhs. All three are hard wired to a managed switch then to the modem/router. I tested before I mined and it was about 25 down and 6MBs up. Can someone enlighten me as to how much more internet speed I need to produce 400Mhs?
