using second router to boost wifi
I have home plugs and a second router. The second router is a dlink (615 I think) which I think supports custom firmware if needed. I conencted it up and gave it its own wifi and things seem to work okay but not great. I notice speed when connecting to it is quite a bit slower and there is lag on my network now. Can someone give a few pointers on what setting need to be set on the second router. For example do I need to change its mac address?
