Comcast, Airport Extreme, Airport Express and large, older home
Hi There,
Greatly appreciate assistance with determining the best home network setup for a large, older home with many brick and concrete walls. The home is three floors high and about 96 feet long. Looking from the front the layout is: front of house, large room, large room, brick wall 1, medium room, stairs, brick wall 2, medium room, small room, brick wall 3, small room, back of house. Currently, we have Comcast Xfinity cable modem/wireless router Arris TG862 on the second floor right before brick wall 1 (it appears to be the most central location). I have an iMac etherneted to the cable modem as well as wireless. Unfortunately, the wireless signal is pretty weak. So I placed an Airport Extreme (via ethernet to the cable modem) between brickwall 1 and brickwall 2 and created a different wireless network. This signal is still pretty weak towards the back of the house.
What are the steps that I can take to maintain a strong wireless signal on all levels and locations within the home? Will another base station help? Does the wireless network from the cable modem create interference? Do I need to reset everything and start over? Thanks so much for any advice
