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!
