Slow connection when connected to satellite

I have an ORBI CBR40 cable modem (firmware version: V2.3.5.12) and an ORBI RBS40 satellite (firmware version: V2.3.5.30). The RBS40 connects to the CBR40 via 5GHz wi-fi and the connection status shows up as "good".

 

When a Wi-Fi device connects to the CBR40, it gets around 200Mb/s throughput, according to speedtest.net . But, when the same device connects to the RBS40 Wi-Fi, the throughput drops to around 50 Mb/s.

 

I connected to the RBS40 via ethernet and the speed was still around 50 Mb/s, so it appears to be a Backhaul issue.

 

I moved the RBS40 to the floor below, and directly inderneath the CBR40 but that did not have any effect on the throughput.

 

Any suggestions on how to troubleshoot this?

    What is your housing materials made of? 

    There should be a minimum of 30ft between router and satellite for them to function properly

    Try enabling/disabling these settings to see if they help: beamforming, mu-mimo

    If you haven't done so since the firmware was updated, try factory resetting and starting over. It shouldn't need to be done but it wouldn't be the first time a firmware update caused issues and a reset/reinstall fixed things.
