RBR20 Router - Number of connected devices possible

I have not seen a published number for maximum devices.  Members of this forum regularly report having 50-60 devices (I have 35).  At least one member reported having 125.  A lot of "Internet of Things" (IoT) devices produce almost no traffic.  The normal DHCP table has a maximum of 253 entries available for satellites and devices.

Of course, there is only so much traffic that can pass through the internet gateway and Orbi, so 50 TV's streaming HD would be a disaster.

Sorry not to be of much help.
