An Ethernet speed of "just under" 100Mbps is a highly suspicious number. (Even 1Mb over 100 would be an entirely different situation.
My first step would be to look at the Orbi web interface, Advanced Tab home page, and click the Blue Box Show Statistics. It should look similar to this:
If the WAN port reports 100M/Full (rather than 1000M/Full) then the modem and the Orbi have determined that the highest speed they both support is 100Mbps.
https://en.wikipedia.org/wiki/Autonegotiation This feature in built into the Ethernet hardware on the modem and router. The user has no control over the process.
There is overhead even in Ethernet, so the maximum speed through a 100Mbps connection is "under 100Mbps".
But wait, "nothing has changed!!!" If the speed has dropped from 800+ to under 100, then something must have changed. Perhaps someone jerked on the cable and pulled one of the pins loose inside the RJ45 jack?
If the WAN port reports 100M/Full, the obvious next step is to examine the RJ-45 jacks on the modem and router and then swap in a different Ethernet cable.
If the WAN port reports 1000M/Full, oh dear!
What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended.

What is the size of your home? Sq Ft?
Does this happen with the RBS turned OFF?
Does this happen with both wireless and wired devices? Different Wired PC to compare

Has a power off for 1 minute then back ON with the ISP modem and router and satellites been performed since last update?
Be sure to restart your network in this sequence:
Turn off and unplug modem.
Turn off router and computers.
Plug in and turn on modem. Wait 2 minutes for it to connect.
Turn on the router and wait 2 minutes for it to connect.
Turn on computers and rest of network.
Has a factory reset and setup from scratch been performed since last FW update?
