Yikes!Tried 43181 and it didn't fix network connectivity loss issue between node and main router for me. Rolled back to 42095 again.
@mrbill, your network setup sounds 'crazy custom' to me.
What are your ISP speeds (up/down)?
How many devices in total are connected wirelessly?
How many connections to students is the educator supporting?
Remove the 4TB HDD from the router (and possibly buy a real NAS instead).
Wireless backhaul (another word for repeater mode) and another contention point for any busy network.
Finally, after flashing the latest firmware to use/test, have you ever performed a full reset to factory defaults afterward? Without using a saved backup config file. And without 'blindly' putting in old settings/features that worked 'once upon a time'?
While the following links are directed toward the RMerlin powered Asus routers, the ideas (best practices) they suggest are applicable to most consumer routers and may be of help to get your router/network to a good/known and stable state with the latest firmware available.
Fully Reset Router and Network
Best Practice Update/Setup Router/AiMesh Node(s) 2021
I have the two pack and did a full factory reset on prior firmware versions to this release without success. Rolling back to a prior stable firmware release also required factory resets in some cases.Intrigued as to whether those reporting issues implemented a full factory reset before use (even if they retained the same SSID) and if they have a 2 node kit?
Interesting. So you're saying only if you made the +1 device the router, and the two pack nodes, you would experience network stability with firmware 42095? Can't say why this would be other than a faulty device(s) in the two pack, firmware failing to update on one or more of the devices (happened to me due to extreme network instability) and/or a failure to truly execute a factory reset. For me, I was unable to use any firmware after 25790 released in September of 2020, which included 42095.I ordered a 3 node bundle (2+1) and found a lack of stability and node disconnections if either of the 2 node kit was the router, even with 42095. Switched to the one node device as the router and the problems disappeared
