check it with a monitor and see if rig doesn't crash and make sure to use lan cable not wireless connection and also did you mined with this rig before ? with normal windows or linux?
if you are having connection issues, what brand router do you have, also do you have any switches as well? also what brand. if you have any with LINK in the name, get rid of it as that's prolly your issue. alot of the consumer grade networking hardware that has link in the name has connection issues and eventually fails IE brands like TP-link,d link, linksys
