What is your network setup ? You dont need another router ... what you need is a network switch
So you setup should look like this :
MODEM - ROUTER - NETWORK SWITCH or MODEM with built in ROUTER - NETWORK SWITCH , then you can connect anything to the network switch with wired connection.
This will not affect the stability of the miner at all will it? For some reason i heard before that the connection may not stay as stable and may keep losing connection to the pool but don't know how valid that was and to be honest this way seems to be the best way to have a setup running by getting a network switch. Thanks for your help.
With a network switch it still means that i will need to have one ethernet cable connecting the two meaning a wire going through my house, sorry i forgot to mention that. That is why i was wondering if a network bridge would be suitable or not.
