Sorry ... are you saying the cascading switches might be an issue or are not an issue ?

Cascading switches is fine as long as you understand what you are doing and the implications .. Say you cascade two 1gbit routers, and understand that limitation; thats ok. It won't affect the tp router.

Also, to be clear .... the router is not constantly rebooting. It just decides it can't connect to the internet anymore; and turning it off and immediately back on doesn't solve the issue (it still thinks it can't find the internet unless it left powered off for a while)

either the router is at its limit or its faulty..

How many devices are on the network .... Wireless and wired?

My money is on a router that is overheating and dying unceremoniously and needing to be turned off for a time for the router to cool back down again. Once it is cool again it is able to boot back up.

If it is your own router then it is either trying to return it if under warranty or I think probably time to get a replacement.

or its at its limit ie with devices, and thus that is the end result. also it may be overheating due to lack of air around the router. At any rate Adam needs to try to recreate the same issue with another router.

Some routers and WiFi systems decide to "stop" running a local network when the internet (WAN) disappears. My friends BT WholeHome WiFi discs stop transmitting a WiFi signal if you disconnect the WAN port on the router, but wired devices carry on working. You'll have to test your equipment for this scenario, and perhaps reconfigure (if possible) or replace.

My ASUS router puts on a red WAN light and continues to provide DHCP and local DNS (of names you configure) to the LAN even with a WAN outage.

That's a possibility but, from what I can tell so far, there is no evidence that the WAN disappeared (the ONT showed green lights throughout) which suggests, to my crazy brain, that the LAN 'spike' caused the router to think the WAN had gone

OK.

Wired - no more than 30.
Wireless - barely a handful (and they are all connected to the eero Mesh; not sure how they then get passed on to the router)

And when the outage happens there is no change in how many devices are connected [ that number is fairly constant 24/7 ]

Green light means ONT can see its other end, doesn't mean that your router can talk to the ISP's DHCP server. You'd need to test your specific equipment, if the ISP provided IP address on the WAN port of your router expires, what happens. Only way to really test is to unplug the WAN cable to the ONT.

I have no idea what a 'spike' is, on an optical medium such as FTTP you can't get electrical spikes that might have been caused by a large amount of load coming on (e.g. industrial machinery) nearby.

two things, when you mean cascading switches, i was assuming you were not talking about the eero mesh 😀.

Adam could you do some checks for me ..

What version is the Archer AX20?

Also what version the firmware is on ?

I just want to exclude if a firmware update will resolve the issue and remove the need to start swapping devices !

Indeed.

My setup is:

eero
|
router --- switch ---- switch

with only wifi connections onto the eero and multiple other wired connections off the two switches

Archer AX20 v3.0

Firmware version 1.1.4 Build 20230219 rel. 69802(4555)

No firmware updates available.

thanks for network map!

Re firmware, theres not much we can do about that !

How many Eeros have you got?

asking because of simplicity/less hassle for you to resolve?

When did this first start happening ?

Also can you recreate the fault or is it random ?

Three altogether; one wired to the router and two others which connect to the "master" eero over wifi

So it has probably happened about 3 times over the last 4 months but the fault is definitely random; in that if that I were to redo what I believe caused it, last time, then it won't happen again if that makes sense.
