So Im going to be building a gaming rig and putting it in a bedroom across the house, my question is will they interfere with eachother or is it no big deal? I dont want to put a wireless card in ao that is why Ill be getting another router. Modems are Motorola SB6121 and the modem I have in my living room is a netgear WNDR3700v.2 and I was wanting to get a netgear WNDR4300 for my room. will there be any issues? wifi wise? they will be about 30' apart. Thanks in advance!
