Orbi RBK852 – Wired via Satellite drops from ~700 Mbps to ~50–80 Mbps until reboot
I’m trying to figure out an issue with my Orbi RBK852 setup. I have gigabit fiber (Verizon), and when everything is working properly I get around 600–700 Mbps up and down, which is great. The pro...

Does this happen if PC is ethernet connected at the RBR?
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?
What is the size of your home? Sq Ft?
What is the distance between the router 📡 and satellite(s)🛰️? 30 feet or more is recommended in between RBR 📡 and RBS 🛰️ to begin with depending upon building materials when wired or wirelessly connected.
What channels are you using? Try 1 and 40 or 11 and 48
Any Wifi Neighbors near by? If so, how many?
DoS protection should be enabled.
Is IPv6 enabled?

- I have never tested directly into the router as it is down in my basement and I am using a desktop so I would have to carry everything downstairs and try to set it up that way.
- It is a Verizon box that I am unsure about the model # but I know it is capable of spitting out 600/700 mbps as I have seen it before.
- Roughly 1800 square feet house. It is a townhouse and so there are 2 floors splitting where router is and the satellite is. so for sure over 30 ft.
- Currently channels are 01 and 44. (Still having same issue) Previously it was 5 and 36 with same issue.
- 5 other townhouses in area with couple houses around. Not an apartment with multiple tenants thought. Probably ~10 other Wifi networks.
- DoS is enabled and DHCP is on

Something to try, can you bring the RBS a bit closer to the RBR? Lets try at 25 feet then at 30 feet.
Is this the only device connected behind the RBS that exhibits this issue? Happen to have another ethernet device you could try with by chance?
Do wireless devices connected at the RBS see same slower speed when doing a speed test?

Also the Verizon ONT Box is a I-211M-K
