@Conway-TWT I looked through firmware notes and the X50 - Outdoor does support a reboot schedule so I don't know why it doesn't work when mixing different models....

  @jzchen sorry I didn't make it clear. Yes it has a reboot schedule, but only for itself. You cannot automatically have the other devices reboot on the same schedule. My brother's network without an X50-Outdoor seems to have the option to reboot everything, though I admit I didn't see him schedule it so I cannot be sure.

My difficulty arose because only the X50 was rebooting weekly, and one of the X55s developed some sort of problem and a reboot of that device was needed, but the main "reboot" button in the app didn't affect it, nor was it clear that it didn't. You have to drill down to the menus for each device to find a separate reboot option. I can do it, but I'm likely to neglect the task 

This behavior is apparently completely dependent upon the firmware available for the X50-Outdoor.

  @Conway-TWT Thank you for clarifying.  I (kind of) understood you were trying to set up an automatic reboot schedule, vs manually going in and rebooting the trouble X55.  I noticed you have an OpenWRT router, then the X50 outdoor as primary Deco.  (If I'm mistaken please correct me).  I can't help but wonder if what you are trying to accomplish would work if you place a X55 in between the OpenWRT router and the X50 Outdoor, then set it up as primary....

I'm afraid I have a single Deco, a BE95, and have yet to add any other so I am practically experienceless...

@jzchen Interesting idea.

I neglected to mention I have the radios turned off on the OpenWRT router to avoid interference, so I'm only using it for its wired router. Essentially I have a Deco-only WIRELESS network. I use the OpenWRT router for traffic shaping, DNS, and monitoring the UPS battery.

As I mentioned earlier I started with a set of 3 X55s and now I essentially have a "spare" X55 that I probably no longer need. My main concern would be whether it might interfere with the (apparently now working well) X50-Outdoor because of the space I have -- the cable modem, router, PoE injector for the X50-Outdoor, PoE injector for the doorbell PLUS moving the spare X55 (and its associated patch cables) into the same area, which is not far from the X50-Outdoor (through a glass window next to the porch where the X50-Outdoor is hanging). Might having the Deco transmitters less than ten feet apart cause a problem?

In any case I have some other projects going so I probably won't get to to this for at least a week. When I started this post I had no idea the capability existed.

The suggestion of changing the main unit would be a decent test to see if I can kludge together a setup that works, even if it's a "waste" of an X55.

Summary: the latest (mid - 2024) firmware for the X-50 Outdoor supports scheduled rebooting. What I don't know yet is whether it actually works to reboot ALL the devices.

@jzchen I had the "spare" X55 sitting next to my router with an Ethernet cable. I reordered my cables and devices to allow another power brick to plug in. AND then it sat for weeks waiting for me to get around to it when others might not be online....

In the meantime, TP - Link was apparently working on an update. For whatever reason, I only just saw the update available last week. I installed it.

It has the reboot feature for the outdoor unit now!

I would like to confirm the reboots are happening on schedule, but I suppose that's "purely academic" if I don't have a Deco lock up again... !
