RBK852 is giving me high latency/delays during video conference (coming from Google Wi-Fi)
I recently switched to an RBK852 system from Google Wi-Fi because of various speed and coverage issues. The Orbi system blew my mind: 3x speed improvement, full coverage, fewer satellites. Everythin...
- ISP is Comcast Business, using an ARRIS SB6141 as the modem
- Both of the graphs are wireless. When connected via ethernet using a 100ft wire into a switch, the graph is pretty much a straight line pinned to the bottom.
- In the graphs, the placement of the routers and laptop are in the exact same place. I made sure that the laptop was connected to router (not satellites) which has one wall and "full cabinet" in-between. Can't be more than 12 ft. House is from the 50's, thin wood walls. But also, i tried this with direct line of sight to the router and again with a satellite. I got the same graph.
- When it comes to settings, they are all default. Coexistence and WMM enabled, CTS/RTS is 64, Preamble on auto, transmit at 100%.
- 2.4Ghz channel is on Auto, 5GHz channel is on 48 (I don't think 5GHz has an auto option, right?)
- ➡️ I'll experiment with the channels (I'll see if I can mimic the Google Wi-Fi settings too). I definitely see other SSIDs, so I have neighbors with Wi-Fi. I need to find a good/simple Mac Wi-Fi monitor/analyzer tool to better understand which channels are crowded.
What get's me, however, is the predictability of the graph... every 45sec or so there is a bump/build-up in latency. It doesn't feel like random noise/congestion/connection-quality. And why everything else is better with Orbi, except this VC issue. That's why I was hoping for a "oh, yeah, that graph shows that you should [do this thing]" type of solution. One thing that I wish I could test with Orbi is setting a "priority device" like I can do with Google Wi-Fi, it may have helped in troubleshooting.
Google Wi-Fi also has explicit toggles to prioritize video conferencing and gaming. I'm guessing WMM is similar? But its a bit opaque about what it actually does.
Additional info if it helps: I have about 50 devices connected. A lot of IoT. Nest/Ring cams. Good mix of 2.4 and 5GHz.

What is the distance between the router and 📡 satellite(s)?

What kind of IoT do you have? Any lights or switches?
- House is about 2000 sq ft. Big open atrium with windows in the center. The distance between the R and S is about 30ft.
- IoT has about 12 non-wifi hue lights (connected to a bridge wired into the switch). No outlet switches. 5 sonos speakers. A bunch of 5 google home speakers, a few nest hubs.
In the diagram below I show the two Orbi devices and where the Mac is. (but I tested in various areas with the same performance)
One thing I wonder is if other people have the same looking Google Meet graph and they don't have problems. (even if I see different graph results on Google Wi-Fi vs Orbi)
I would try this to test. Change the SSID name or change the PW to something different so that it disconnects all wireless from the system. Turn OFF the RBS. With the one wireless PC check your app again.
For that size of home and distance, I would turn down the power transmit on the RBR from 100% to 50% as well. Under Advanced Tab/Advanced Settings/Wireless Settings
Funny, I was also thinking about trying the SSID name change (!). I'll be able to experiment later when I return home, but here is my list.
- Isolate the computer to a separate SSID with only the RBR powered on. Test.
- Turn down the power transmit of that RBR. Test.
- Analyze Wi-Fi channels for congestion (looks like inSSIDer has a Mac app in beta), try switching 2.4/5GHz to cleaner channels. Test.
Should I still do #3 and if so, if #1 and #2 don't show improvement, should I keep everything in the isolated environment (from #1)?
- How are you Sonos connected to Orbi? Any of the speakers wired?
Also are the satellites wired or wirelessly connected to the Orbi router?

When I first set up Orbi, I tried powering them all down to see if they had any affect on performance, they do not seem to. But I will keep them off when I try messing with the settings.

All the rooms on the right side of the house diagram have ethernet, however, I got coverage issues and a drops in speed if I moved the Satellite into one of those rooms for a wired connection (especially in the top left area of the diagram)
