ORBI RBR/RBS50 sporatic latencies between hosts on the same wifi lan FW V2.5.1.8
lately connectivity has been not so smooth, i started noticing periodic short hangs using remote screens between computers on the same wifi lan at home. AT&T Wifi also gets pretty bad receptions, audio cutting out, eventhough wifi signal was full and internet speed checked out okey.
I started doing basic pings, while pinging ORBI/router resulted fine, pinging nodes on the wifi lan seemed otherwise. I've narrowed down to pinging devices from RBR50 client to RBR50 client are okey, but client on RBR50 pinging RBS50 client resulted bad latency. Here's short example

I have obviously rebooted/power cycled each RBR/RBS50, internet modem, client devices ( laptop, appletv, webcam etc ) and both RBR/RBS50 running same and latest FW. Nothing made difference...
RBR50 and RBS50 have a few walls and about 25-30 ft apart.
The web app also doesn't seem to list out all devices, only some... and per RBR/RBS device listing is always empty

Two additional diagnostic steps might be:
- Look at how congested the WiFi space is, especially the 5G "backhaul" channel between the Orbi router and satellite.
Most WiFi analyzer programs (Android, Windows) will show how many access points are on each channel and the perceived signal level. The "backhaul" channel will hav no SSID (hidden), and is often on channel 157 in the US. - Telnet into the Orbi router and type this command:
satelliteinfo wifi
That will show the "link rate" between router and satellite. For example my Orbi shows this:
{
"mac address" : "A0:04:60:0D:96:FA",
"hop" : "1",
"bridge mac" : "A0:04:60:0D:96:FA",
"backhaul conntype" : "5GHz",
"backhaul rssi" : "-67",
"backhaul macaddress" : "A0:04:60:0D:96:FD",
"backhaul phytxrate" : "975",
"backhaul phyrxrate" : "1170",
"backhaul parentmac" : "A0:04:60:1C:02:39"
}
Thanks much! The command on mine showed the following line with "rate"
"backhaul phytxrate" : "1733",
"backhaul phyrxrate" : "1560",
May i assume these numbers look healthy?
Thanks!
I am also seeing some abnomalies.
On IOS app, both RBR50 and RBS50 were shown with green status and connected. In the web UI, however, shows connected satellite = 1, backhaul status "Disconnected"
Given satelliteinfo wifi command returned stats and IOS app is shown with green status, i am guessing this would be a Web UI bug?
- Look at how congested the WiFi space is, especially the 5G "backhaul" channel between the Orbi router and satellite.
I have a router and 2 satellites. One satellite is wifi backhaul, the other is wired backhaul.
When I telnet to the router and ping the wired satellite, I average 0.6 ms (rounding). When I ping the wifi satellite, my pings average 3.3 ms (rounding).
In both cases my mins might be half of the average, and my max might be twice the average. That still only puts me a few ms apart, far from the variation that you are seeing.
My sattelite info lists for the wifi backhaul satellite details:
"backhaul conntype" : "5GHz",
"backhaul rssi" : "-55",
"backhaul phytxrate" : "1170",
"backhaul phyrxrate" : "1170"
I kind of find the rssi interesting as the router is on the first floor, the satellite on the second floor, with a number of walls along the way; they are not directly above each other. But hey, I'm not complaing. Once could argue, these might be too close.
The router and the wired satellite are on the ground floor about 60 feet apart with of course walls along the way. Without the direct cable, the connection between the two was unstable at these locations with the devices flipping from blue to pink randomly; hence, it appeared I was at the edge of its connection range for these two.
I only give you the above as a point of reference.
Personally, I feel your router and satellite are too close together.
What happens if you pull the satellite out of the mix and just have the router?
I found a different thread that described most of same issues and the solution was to downgrade to a previous stable fw version. However, i am not able to find relevant info on downloading previous FW and installation instruction for downgrading. The thread is here
Replacing Orbi firmware is tedious, but not too difficult - especially if one has a computer to wire to the Orbi.
Browse to https://netgear.com/support Enter the model number RBR50 and click on Downloads. There is a link to firmware 2.3.5.30. Download the zip files for both router and satellite. Unpack (unzip) the files to extract the .img files.
Then use the Orbi web interface, Advanced Tab, Administration, Firmware Update, and select the "Manal Update" tab.
Good Luck!
