Controlling Link Rate

The link rate that you see in the Orbi app for each device depends on the following factors:

1. MCS index: Indicating the used coding scheme, the choosen coding depends mainly on the radio conditions of the link and on the capability of the device.
2. Channel bandwidth: Possible bandwidths are 20, 40 or 80 MHz. This also depends mainly on the radio conditions and the device capabilities
3. Number of spacial streams: Whether the device supports dual MIMO or not.

So for Apple TV 4K, which has dual MIMO capability and supports 80 MHz cahnnels bandwidths and 256 QAM (MCS index 9), the only dependency in your case is the radio conditions. Please make sure that the distance between Apple TV and Orbi is not too long and there are no obtacles in between. Please make also sure that ATV is using the 5 GHz channel and not the 2.4 GHz, reboot ATV to change this.

Please try also to choose different 5 GHz channels than those used by your neighbours. Try different channels and see if you get better rates with the different channels.

Parameters in Orbi to check are:

• Enable MU-MIMO (ensures that Orbi uses MU-MIMO)
• Enable WMM (Wi-Fi multimedia) settings: Gives priority for media traffic over data traffic in Orbi
