HORRIBLE wifi speed but ULTRAFAST via ethernet ports
Issue: Cable modem (SPECTRUM) delivering 350+ Mbps INBOUND with near equal throughput (measured via FAST.COM) to devices via Ethernet ports on two satellites. Wifi throughput, HOWEVER, typically...
I do not like the "Blocked" business with Satellite #1. Thanks for taking the time to install WiFi Info View. Not being able to come up with any reason for WiFi device performance to be so low, I was grasping for anything. Such as, "maybe the 5G channel is SO SATURATED that nothing can get any air time." The results do not appear to support that hypothesis.
5G WiFi is a bit confusing. (WiFi in general is damn complicated in my opinion.) The router attempts to use an 80MHz wide channel (to get 866Mbps maximum throughput with QAM256 encoding) by combining channels 36, 40, 44, and 48. When the customer "sets" a WiFi channel, that means the router uses that channel for management frames, such as Beacon Frames and set up communications.But, it still tries to use the maximum possible bandwidth based on the capability of individual devices.
It's hard to even imagine what is going on. "Oh, you're a device that can do 802.11ac with 2x2 MIMO, set your radio to xxx and transmit to me." "Oh, poor camera, you can do only 802.11n and no MIMO, I'll talk to you at yyyy." Every transmission.
(A similar thing happens with 2.4G WiFi. If the network actually has an 802.11b device on it, communication with that specific device has a maximum Link Rate of 11Mbps (https://en.wikipedia.org/wiki/IEEE_802.11b-1999 ). When an 802.11g device comes on, the maximum link rate is 54Mbps (https://en.wikipedia.org/wiki/IEEE_802.11g-2003 . Only 802.11n devices are capable of reaching that mythical 400Mbps proudly touted in the RBR50 product data sheet.
Even if we add up the "utilization" of channels 36+40+44+48 in that report, it comes to 30.9%. (Not forgetting that we have no idea what the hell that report is actually measuring.)
Having failed miserably to find a solution, I can think of only one more step: the dreaded Factory Reset. My practice is to first try a "quick reset":
- Save the configuration to a computer (web interface, Advanced Tab, Administration, Backup Settings.)
- Get out the paperclip and hold it in the tiny "reset" hole until the power LED begins to blink amber. (about 10-15 seconds).
- Let the router restart. (the web interface goes back to "admin" and "password")
- Go through the setup process and do not change anything. Leave the WiFi SSID/password the way it is. Do not "register" the product again. Do not sign up for anything (Armor, Parental Controls, etc.)
- Just power through until you get to the page that offers two choices:
- Load a saved configuration, or
- Continue to configure manually.
- Load the saved configuration. The router will reset all by itself. And, everything comes back. (SSID/password. Admin login credentials. IP's assigned to devices. DNS servers. etc. etc.)
- One time for me, whatever junk had accumulated and caused my router to act up was now gone.
Takes 10-15 minutes maximum. No data entry (no chance for typos). No WiFi devices get the wrong IP addresses assigned to them. Wham. Bam. Thank you (oops)

So, I rebooted RBS50#2 and achieved 300+ Mbps. I then left it to run for 2 hours. I just rebooted RBS40V and I am still seeing 300+Mbps for my measurable wifi devices.
I think the key was shutting down all satellites and rebooting them one by one.
Only time will tell but i haven't seen consistent throughput like this since I set this system up.
Late to the party again (darned weekends).
I did notice from your attached devices lists that when you were initially testing, those devices were on the 2.4ghz band and not the 5ghz. The reboot might just have triggered them to reconnect using the 5ghz.2.4ghz is a much slower network and sensitive to interference. It'd explain the 6-50mbps that you were hitting.

Everything was perfect until I booted the RBS40V. For whatever reason, that device is not playing nice with the RBX50's.
I turned off the RBS40V and decided to look for a used RBS50 off ebay and then remembered I have a spare RBR50. Is it possible or advisable to repurpose the RBR50 in AP mode for the Ethernet connection to the 1 camera?
All I need from that particular device/location is to connect a camera via Ethernet. Do NOT need it another wifi signal.
I also have an old LINKSYS WRT1900AC sitting around but would prefer to use Orbi devices exclusively.Sad that the RBS40V is not 'playing nice'. I have two of them with one RBR50 and one RBS50. "No problem."
The major issue with using a router to extend WiFi service to a device is that routers must be connected using an Ethernet cable. (this would apply to both the Netgear RBR50 and the Linksys router.) If you can run a cable for the router, that same cable would have serviced the camera.
If that camera absolutely requires an Ethernet connection, I would look at an inexpensive WiFi Extender which will connect to the home network over WiFi and provide an Ethernet port for the camera, such as the Netgear EX3700 (under $30 on Amazon).

I had one of those at one time but never was satisfied with its performance. Tried to see if I still have it but it isn't in my "spares" box so I must have tossed it.
So I just purchased a "like new" RBS50 off of ebay for $100 that should arrive by the weekend. Hopefully that will put this issue to bed once and for all.Sounds like a good solution. I have an Orbi satellite in my garage with an 8-port PoE switch connected to it. Got tired of finding electrical outlets for cameras.

Well, nothing would bring the wifi back to where it was yesterday. I did 2 factory resets.One with the pin and one from the Orbi interface and neither restored wifi signals.
I finally decided to use the spare RBR50 instead of selling it. So far I was able to update the firmware and restore the configuration, make adjustments to the access control devices and add the 2 satellites.
It is extremely important to allow the RBS50's time to assimilate into the network individually. For whatever reason, the first RBS50 produced 2 additional mac addresses in addition to the one (9C:C9:EB:2C:77:BF) listed at the top of attached devices. They all listed the same IP address but 3 total unique mac addresses.
I'm posting an image of access control with those 2 additional mac addresses associated with 192.168.7.8
It takes the system about 5 to 10 minutes before those extras listings that appear in access control after adding an RBS50 disappear. Once that happens the mesh provides FAT bandwith for my wifi devices again. Pretty much what the Ethernet ports are providing.
I'm apprehensive of adding another satellite and almost wish I'd just bought a new camera now that everything is smoking fast again. If I add the 3rd RBS50 and everything goes south again I'm going to blow a gasket. 😁I received the new RBS50 and had a bit of trouble adding it via the Orbi app. So I decided to update the firmware manually since I already had 2.7.4.24. However, when I logged directly, it spit out an error that this wasn't the correct firmware etc...
I doubled checked, tried again and ended up using the router interface to automatically download and update.
It rebooted and all 3 satellites show GOOD backhaul and my wifi devices are still consistently pulling down 300+Mbps.
HOORAY!!I sometimes get tangled up by confusing the router firmware file with the satellite firmware file. After all, they differ by only one letter ("r" or "s") Click the wrong one, and "incorrect".

Doh! I resemble that remark. I forgot they were different. If the Orbi interface hadn't worked I would have eventually discovered what I forgot.
