Orbi Satellite Slowdown
I continue to have problems with one Orbi satellite that after two-three days of use slows it's throughput dramatically. I can normally connect and get a full 300 Mpbs connection via the satellite, ...
I am having this same issue and would love a fix. This has been happening since I set up the system about 10 months ago. If I restart the system everything goes back to normal and I get the full speed of my internet connection (around 250mbps). After a few days the speed on all devices drops to 40mbps or less. The only thing that seems to resolve the issue is to restart the router. This is happening on my laptop even in the same room as the base unit so it isn't a week signal issue. One day it will be full speed and the next with no other changes it drops to 35 - 40mbps.
I have the Orbi Orbi RBK20W (AC2200).
1. Can you please check which radio channels the slowed down devices are using during normal operation and when the issue appears. Don’t the devices change from 5 GHz to 2.4 GHz? Do you have fixed radio channels for 5 and 2.4 GHz bands?
2. What wired devices do you have attached to Orbi? Wired devices can cause loops in the system if wrongly configured.
3. What is the model of your ISP modem/router? Is Orbi operating in Router or AP mode?

The issue has occurred on all radio channels as one of my early troubleshooting steps was to try different channels. The affected devices are all connected on the 5ghz band. I do have a few devices connecting on the 2.4ghz band but I am less concerned about the speed of those and therefore haven't checked if they are affected in any way.
Currently I have the 5ghz channel set to 36 and the 2.4ghz channel set to 01. In the past I have set 2.4ghz to auto as well as 06 and 11. I have also tried the 5ghz channel 40. When the slowdown occurs I have double checked what the client and what the orbi router report and they both state that the device is connected via 5ghz. So although the speed decline would seem like it is connecting at 2.4ghz that doesn't appear to be the case.
I have one wired device. It is a mac mini. Running speed tests on that computer show that it is getting the full speed that my internet connection allows. I have also unplugged that device and it did not improve the problem for my wireless devices. The computer is set to use DHCP and so does not really have any custom configuration and is operating properly so I don't believe there is any configuration issue or hardware issue with it.
I am using Comcast cable internet for my ISP and the modem is a Motorola MB7621 DOCSIS 3.0. It is not set up as a router so I do not have a double router (nat) situation going.
The orbi is operating in Router mode. A simple restart of the Orbi fixes the issue for days and my wired device never experiences any slowdowns so there shouldn't be any issues with my cable modem.
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 them to begin with depending upon building materials when wirelessly connected..
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. Save settings and reboot the router and satellite(s).Has a factory reset and setup from scratch been performed on both RBR and RBS?

The house is 2100 sqft. My satelite is about 25 ft from the base unit. They are on different floors but it is a fairly straight line of site path down the stairs and the backhaul status says "Good". I get the same speeds when connected to the satellite or the base unit so I don't think there is any bottleneck there.
I definitely have wifi neighbors but I use a wifi analizer app to determine which channels are unpopulated and have my orbi set to use those. I have tried different channels but currently no other router is on the channel I have things set to on the 5ghz band and there are some very week signals on the 2.4ghz band. Restarting the orbi and leaving it on the same channel resolves the speed issue for days so this shouldn't be an interference issue. It also doesn't change once it starts going slow as once it is back to 40mbps it stays there until a restart. This isn't something that fluctuates. It is either running properly or it isn't. A reboot is the only cure.
I have tried many combinations of settings with no help but currently I do have MIMO and WMM turned on. I have never enabled Armor or Circle. I have tried with Daisy chain enabled and disabled but it currently is disabled. IPv6 is currently disabled. I don't see an option to set 20/40Mhz Coexistence to 40Mhz only. It is just a checkbox to enable or disable it. I guess I could disable it and see if it helps. I feel like I may have already done that but I could try to disable it.
I have performed a factory restore once shortly after purchasing the unit but that did not have any affect as after a few days the speeds went back down to 40mbps.

The Motorola MB7621 supports 24 downsteam and 8 upsteam channels. I suspect that this is a capacity issue!
If you stream video from multiple devices at once, or someone in your household engages in activities like gaming or video editing then it can be that you are consuming more channels than what the modem can handle. Do you think that this applies to your case?
If this is the case then the only thing that we could try from Orbi's side -although not straigt forward- is to reduce the tcp session timeout in Orbi and see if this will improve the situation. You can also try with another modem if you have the possibility.
I don't see how this could be related to the cable modem as the one wired computer to the orbi naver has any speed issues and speed tests report my full internet speed directly on the router too. This issue only affects my wireless devices, and again once the slowness occurs it never recovers back to normal regardless of what is happening on my network, time of day etc. I have tested late at night when everyone in the house is asleep and there is close to zero traffic on the network. If the speed fluctuated based on use then I would be inclined to believe that could be the case but that's not how this issue manifests.
