RBR50/RBS50/RBSS50Y - Auto/manually setting wifi's devices' preferred SSID IP addresses needed!

What you are asking for is to make Orbi control the roaming decisions. Please note the following: 

1. Roaming decision is always taken by the device not the wifi router (the AP which can be the Router or any of the Satellites). The AP can just help and suggest to the device to roam but can't take the decision to roam.

2. Orbi supports 802.11k, v and r to enhance wifi roaming.

3. Orbi uses band-steering (part of 802.11v) to force the device to move to the band in the Router/Satellite that the device receives better.

4. There are devices that do not support roaming enhancement standards, usually called "Sticky devices", those devices can cause bad user experience. For those "Sticky Devices", what Netgear can do to improve the user experience is the following:

   1. To implement a Min_RSSI_Value -I don't see that this is currently implemented in Orbi. This is a value that can be configured on the AP's (individually in the Router and all Satellites) per radio band so that a wireless device is required to meet a minimum signal level, as seen by the AP, to be able to reliably connect/use a particular AP, otherwise the AP will take action against that device.

   2. This works by sending a de-authentication packet to the wireless device that does not meet the minimum RSSSi requirement (the Sticky Device), which effectively tells the device that it's not welcome on that AP, It is then up the device to find a better AP to connect to. It may connect back to the same AP, especially if it is the only one within range.

   3. This should be configured on a per AP basis. This does actually require some careful configuration, and -probably- that's why Netgear chose not to implement it on this non-enterprise product.
