Orbi SXR30 Magenta light - repeatedly loses internet connection
Model SXR30 firmware version 4.2.0.122
I see many posts here as well as elsewhere on this. I loved this product until about a month ago and now it is very flaky. It will randomly drop its internet connection. I login to the router and see that it says "waiting" or no connection to WAN. I then bring up xfinity connection status on my phone, and all is well. xfinity sees my modem, can reset it, etc. I have an Arris cable modem.
If I reset the Orbi, it sometimes works. I've reset both the cable modem and the router, then did a factory reset. It won't last and will eventually drop again. I saw on other sites that downgrading the firmware helped. When I managed to get the internet up for more than 5 minutes, I quickly downloaded all the available router versions. I am now trying out version 3.2.33.108.
Because of the many forum posts both here and elsewhere, I would say this is systemic. Whatever it is needs to be fixed.

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
What all do you have connected to the SXR?
Any LAN switches by chance?
Notice any ARP Storms happening on the LAN?
Can you access the SXRs web page still?
The router is connected to my ISP (Xfinity) via an Arris SB8200 cable modem.
I have two netgear switches, daisy changed downstream from the router. I can access the orbi maintenance page (192.168.1.1) even when the WAN connection has dropped.
On the SXR, I have the switches, and a single receiver for the solar panels on my roof. That receiver has a little antenna to get data from the panels, which then sends the production data to Tesla over ethernet.
Are you suggesting I use tcpdump or something to determine if there is an ARP storm? I cannot imagine anything I have would send ARP storms.
Does the SXRs web page show that the internet is down when this happens?
What are the model #s of these switches?
How often does this happen?
One way to check for ARP storm is to look at the switches All LED activity. If there all constantly flashing or ON, means there a ARP storm happening. LED activity should be random blinking unless your downloading or streaming something on a particular device. I saw this yesterday after putting my SXR30 online with a CM2000. I don't know if turning on a ethernet connected SXS30 triggered it or not. I wasn't looking at the front LED until I happened to see one of my switches constantly blinking. Then looked at the SXR and front LED was PINK.
I'm going to try a reset and setup from scratch and put it online and test the SXR alone with one PC, then add in the network, see what happens, then try adding the SXS. This storm doesn't happen with my other routers.
If you downgrade let us know the results.

What is the CAT# cable between the SXR and ISP modem? CAT6 is recommended.
I am using Cat 6 cable between the SXR and cable modem.
