Ok first some background. I have a 3 story townhouse. My modem is on the top floor connected to a 3rd generation aebs. It works but it doesn't hit every room in the house. We live mostly on the middle floor where the signal is sub par. I ordered the new aebs which should be here friday. My question is should I keep the same setup and add the new aebs to the middle floor and set it up to extend my signal or should I replace the top floor aebs with the new one and bring the 3rd gen one to the middle floor?
