trying to connect satellite by ethernet

[DMR54]

Hi:

I am having trouble connecting an RBS20 satellite using a wired connection. I have a HItron cable modem and a RBR50 in AP mode. I have one RBS50 satellite using WIFI connection. RBS20 connects fine using WIFI, but want a wired connection if possible as in a corner of the house. The Ethernet cabling in the house is rather odd -  only a few runs come to a central location (in the basement) and most is connected in various wall outlets, in some strange daisy chain.

Anyway, I can only get the RBS20 to be a wired connection if plugged directly into the RBS50. If I plug into a switch (that is getting internet, as use it for TV), it shows as offline. Have tried rebooting etc. but haven't been able to solve yet.

Any thoughts?

What is the Mfr and model# of the ethernet switch in the configuration?

Be sure the switch and cabling are configured as seen here:

NG GS-105/108v4, D-Link DGS-105/108 and HP ProCurve 1400/1800 series switches work for Orbi systems.
