RBR40 Slow Ethernet Connection
I have been having this issue for a few months now, before it was working totally fine and I had not changed anything. It seems like every device plugged into ethernet of the router gets capped at ~80Mbps. Speed test on the router itself in the Orbi app show speeds above 150Mbps like it's supposed to, and wifi devices are the same. Devices connected wired include my PC, game systems, and TV, and all have the same issue. I tried directly connecting a laptop too and had the same problem. I tried a standard factory reset with the reset button on the back, but that didn't fix it. Also firmware is up to date, and has updated a couple times since the issue with no change.

That sounds like full duplex auto-negotiation has failed between Orbi and your PC. If your PC is awake, it shouldn't say 100M/Full if auto-negotiation works correctly. It could be that the cable has gone bad. Otherwise, you can try to change the PC NIC setting to force it do to 1000M/Full. If you have a Gigabit switch in between, that will tell you for sure where the issue lies.

TG360, it sounds as if the WAN port has correct link speed (1000M/Full), but the LAN ports are not (100M/Full).
To check link speed, point your browser at (replace 192.168.1.1 with your Orbi IP address):
If LAN port says 100M/Full, disconnect all cables from LAN ports, stick a paper clip in the back of Orbi until LED blinks amber. If reset still doesn't fix it, find a Gigabit switch and put it in between Orbi and clients to see if that will make a difference.
