I'm trying to solve a problem with wifi in my house. The situation is this: my house is large, over 2600sf. The modem and Airport Extreme(4th gen) is located at one end of my house in the living room, where the Apple TV is. My computer is located at the opposite end of the house in the family room, about 80 feet away and half a floor down(split level). I recently had been using an Airport Express in the family room to extend the network to help with wifi coverage to the computer and the bedrooms which are located above the family room. The Airport Express(model A1264, previous to current) has been failing lately and I suspect it isn't really up to the task I am asking of it. My quandary is this: should I run ethernet from the Airport Extreme to the family room and connect it to the Airport Express to help alleviate it's workload? In the event I have to upgrade the Express, I'll probably go with a 5th gen Extreme(newest) and swap it with the 4th gen Extreme. Does this idea make sense? Using ethernet to wire the signal to the other end of the house to then broadcast as wifi? Will the Extreme extend a network through ethernet to another Extreme/Express? Or just get another Extreme and skip the ethernet? As it is now, the Extreme by itself can't provide a reliable signal to the family room, it cuts out periodically but there is still wifi in the living room, so that's how I got to this possible solution. Alternatively, I could try to relocate the modem and Extreme to a more central location, and that could just save me some money but take lots of time configuring a place for it so that its not tucked back in a cubby or just sitting out on a shelf looking obtrusive. Even then I may find I still need a secondary router. Your thoughts please?
