Go through everything connected to the router itself, disable one at a time, reset and wait to see what fixes it.

Good observation Geddy007. I think I've seen similar behaviour in my Orbi previously. What is special with this TV? Does it also have a wired connection to the network? Was it attached with Orbi previously as wired? Does the TV also act as an AP? Please look where this TV can cause loops in the network by having two different interfaces.

  TV was never wired - always wifi. It's not an AP that I know of. I never really even used the wifi connection, since all my entertainment comes through FireTV stick. The TV wifi connection was only used for the TV to get software updates for itself, which I don't really need. Now, if I want to check for a TV software update, I can manually connect to check and then erase wifi settings again.

    Then it must be a bad wifi module on your TV.

What is the size of your home? Sq Ft?
What is the distance between the router and satellite(s)? 30 feet is recommended in between RBR and RBS to begin with depending upon building materials when wirelessly connected. https://kb.netgear.com/000036466/How-far-should-I-place-my-Orbi-satellite-from-my-Orbi-router

What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?

Try enabling Beamforming and MIMO(MIMO may or maynot be needed) and WMM. Under Advanced Tab/Advanced Settings/Wireless Settings
.
Try disabling the following and see:
Armor, Circle, Daisy Chain, Fast Roaming, IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Set Short preamble instead of Long preamble modes. Save settings and reboot the router and satellite(s).

Above suggestions working:

I had the same problem, but it's now fixed. Wired speed from router to ISP over 200 Mnps, same on wifi for router and satellites. After 2-3 days, wifi when connected to router dropped to 40, but both wifi through satellites and wired from router to ISP remained over 200. So, it was solely a problem with connecting by wifi to router itself.

    EQUIPMENT: RBR40 with a Satellite (latest firmware (V2.3.5.32) as of april 2020).
    I and was experiencing the same behaivor everyone on this thread has been messaging.
    
    To recap..
    
    The issue with download speeds limited to 40Mbps, would present itself about 3-4 days after reboot.
    Restarting the router would temporarily resolve the problem.
    
    Factory reset did not fix the problem.
    Tuning down the 5ghz to 75% and 2.4ghz to 25% didn't help.
    Mixed 20/40 mhz being disabled, did not help.
    
    Eventually, I unplugged my satellite, and the issues did not persist. I am noW 11 days in, no problems,
    
    I noticed my Surface book laptop which was 4 ft from the router (through a wall), would connect to the Satellite (50ft away, via many walls).
    So i think either with an update, the mesh was no longer coordinating with my devices to have them associate to one AP or the other.

Geddy007 Identical problem here (RBR20+2 RBS20). Full speed for 4-7 days, then drops to 40~45Mbps, but only to WiFi devices connected to the router, not the satellites (strange). I tried disconnecting every device to no avail, but I forgot two - the Samsung smart TV, and a little Netgear dongle that connects to the dish satellite box to download the guide info. I will definitely try those next...

I think you are the only one who actually solved this problem!

  Fingers crossed - let me know how it goes. I haven't had the problem since I blocked the TV.

Geddy007 I just disconnected the WiFi USB dongle and the Samsung Smart TV WiFI - no change in the speed. I believe you said you had to reboot the router - so you didn't see the speed improvement right after the disconnections? Did you confirm the reboot was required?

  Yes, I had to reboot the router after disconnecting the smart TV. After that, it has stayed fast for me for months after that and didn't drop every few days any more.

    For the tech saavy on this thread who don't want to shell out another $400 for network gear.
    
    A weekly reboot does the trick. I have a raspberry pi at home, and setup a script to execute on the crontab and it's worked like a charm for a month. This script will log an entry to the system log with the prefix "[orbi]" if you wanted to see any history.
    
    Crontab Entry - I keep this script in /opt/scripts/orbi, you can store it where you like.
    #Sunday
    30 6 * * 0 /opt/scripts/orbi/invoke-reboot-orbi.sh
    
    Bash script below, found this on github and slightly modified.
    
    #!/bin/sh
    #Parameters
    ROOT_DIR=/opt/scripts/orbi
    USER_PASS="your password"
    LOGGER_TAG="[orbi]"
    logger -t $LOGGER_TAG "Rebooting Orbi...."
