Also, when using a LAN straight from machine to machine you MUST use a crossover cable. not a 'straight-thru cable.. The LAN ports to not autoconfig what is the Tx and Rx lines. A hub has same problem, using any reasonably modern LAN switch between the miner and computer takes care of the issue as would a crossover adapter..
Thank you so much, I haven't though of that actually, ill try to get a crossover cable or circumvent that issue somehow using a router with static ip list and nothing else connected, luckily i had written down the mac address
