Guys so I have a few antminers and for some reason I cannot get them online. Here's the situation:

Modem - - > router/ethernet hub - - - > my computer and antminers.

My computer is getting signal perfectly but when I do an ip trace, I do not get the adress of my antminers... Also the one time I got the adress of one, I accessed it for a few seconds and then I was unable to reach the gui again.

The router log says that it stopped attack or something like that (I assume it's from the packet sending/recieving of the machines)

Also, I tried directly with the modem and nothing. In fact I can't even log into the modem settings.
