 What would be the best setting for and office that has 3 WAP?
Some people say that you should put all the WAP's on the same channel and others say that you should make sure that the channels are 5 MHZ apart, so using channels 1,6 & 11 would work.
What is the correct way?

    I think you will get varying answers.

    What I would do is 1,6,11 with same SSID(assuming you want them the same).

    Agree, but whats the correct way to do it?

    I was thinking of using 11, 1 & 11..
    The WAP's with channel 11 are far apart enough.
    What do you think?

    Hmm, what is correct (?)  I would say that is dependent on what works for you infrastructure and the surrounding interference. The right way is the way you find to be stable given your situation ;)

    If the WAPs are far apart and will not interfere, using the same channel is fine.  Separating the channels minimizes interference (overlap).

     So there is no hard set rule when it comes to setting channels for a WAP?

    This might change for different vendors. What model APs do you have? i know that Meru wants to put all APs on the same channel to get no roaming and create something called Virtual Cells/APs  for each user. This works really good for some scenarios but not as good for others -- But this is specific for Meru.

    Otherwise you should put APs on different channels, because a sending station reserves bandwith for the station when it sends - so if you have to many APs on one channel you could have one station silencing other nearby APs when it sends. (Unless you have Meru which has a different design)

    If possible, you should use 802.11a (or n if possible). Here you have so many channels that it's not a problem.
    If you need to use 802.11b/g - then 1 - 6 and 11 is the ones you can use (since there's overlapping between channels)

    Try setting APs to 1 - 6 and 11 and download inSSIDer from
    Do a survey of your WiFi environment after you've implemented the AP. This program show what channels an AP spans over and will also pick up other APs nearby - so here you'll get a real good overview of your APs and interference
