dctheobald - Since you mentioned wiring your office, I have more bad news! A few weeks ago I finally broke down and paid to have my home wired (which cost thousands of dollars). There are three people that work from my home frequently. After a year of being interrupted to look at the Orbi's multiple times almost every day, I finally caved and spent the money.
I know for certain that the ethernet backaul feature of the Orbi's, at least as of firmware version 2.1.2.18, is too unstable to use. There is no way to force the Orbi to use either the ethernet or wireless backhaul, and the system will not consistently stay on one or the other. The net effect is that you can end up with both the original stability issues (if an Orbi decides to use a wireless backhaul for whatever reason), or deal with a broadcast loop caused by a multi-path issue (both a wired and wireless path to a MAC address), or deal with random "cut outs" for all devices as the Orbi changes from using an ethernet vs wireless backhaul.
Also, even if the Orbi's stayed on the ethernet backhaul for the day, I still ended up having to restart one of them nearly every day.
Since I had paid to wire my home anyway, I spent $650 more and just bought a Unifi 5 pack. Litterally, 0 issues since then and it's been several weeks. No drops, no pauses, no complaints, it just works. I'm even able to do proper channel organization, though that's just a bonus. Interference was never the problems with the Orbi's. For reference, I have between 6-10 devices using traffic all day, and 20-30 devices using traffic intermittiedly.
If you're paying to wire the place, just get a more professional product (like Unifi's or, really, anything else).
