    Hi all,

     

    Do anyone have some best practices guidlines for me regarding DTIM interval?

    Best setting for VoWLAN: 1 beacon?

    Best setting for High Speed Data: 3 beacons?

     

    Many thanks in advance!

     

    Kind regards,

    Leave it at 1, unless the manufacturer of the device specifies that you change it.

    Apple, for instance, recommends a DTIM period of 3. Ben Miller goes into great detail about it here:
