I have a five room, 114m^2 (1200square feet), single story apartment. I have two routers set up. One working as a proper router and one functioning as a pure WAP (it has wired access itself). It is very clear from careful measurement that I definitely need two routers as opposed to one to get good WiFi coverage in the whole apartment.

I have set up these routers in opposite ends of the apartment (It would perhaps have been better to have a single router in the center of the apartment, but that is not possible for several practical reasons).

Now, I already own a third router (hardware identical to the WAP) that I could set up as a second WAP, potentially forming a fairly equilateral triangle of routers. The third router would also have wired access itself.

Will I get even better WiFi reception with a third router? Or will the routers interfere with each other, and perhaps even make the reception worse? (It is a big apartment house, so there are already plenty of WiFi routers in the vicinity)

The hardware in question is an ASUS RT-N56U Dual-band Wireless-N Gigabit Router Router as main router and two Netgear WNDR3700v1 (running DD-WRT) as WAP. So all routers have dual-band, support 11n, and are fairly high-end. They are all configured to auto-select appropriate channels.

Are you noticing that some parts of your apartment are still not getting good coverage/signal? – iglvzx Nov 21 '11 at 18:43

Two is plenty for 1200 sq. ft. If there is a lot of interference in your apartment, then you may add another. However, if the routers are on different channels, then they should not interfere with one another.

But if they are on different channels, can he move around the apartment (with his mobile for example) without losing WiFi connection? – Yousf Nov 21 '11 at 19:13
That is a good question. I am curious myself, so I just asked SU. – iglvzx Nov 21 '11 at 19:41

This is not a direct answer to your question, but if I were you, I would:

  1. draw a rough top-view-map of the house
  2. get Wifi signal analyzer software (for android, iphone or laptop)
  3. create a heat map for the wifi signal.

You might also try Meraki WiFi Mapper service.

I have apartment of more than 140 meters and it is covered with just one ADSL router placed at the middle, but signal is weak at the both ends.
