@David-TP Thanks for your reply.

Aah yes, i do recall it being an open network when i first set it up..

Yes i did find that that SSID+Password showing up for both 2.4G & 5G networks in my Deco App.
I checked this morning and noted that the LED was green(Maybe tinge of yellowish.. but that could have been my bleary morning eyes)

After updating the firmware and rebooting it was green, and remains green.

I've tried to set the same SSID and password that i set up after i purchased the Deco X55, but it's now not accepting the password i configured (I used spaces. and the app is telling me that i cannot use spaces)

Thanks

Thanks @David-TP 

The spaces in the password are my new problem (otherwise I could just set the same SSID and password as before & ALL my devices would connect back fine…)

but now I will have to reconfigure every single device I have, just to remove the spaces from the password😫 (this also means reconfiguring many automated routines within various apps etc..

Is there a way I could please get the old app to set up my old SSID and password with spaces please? 🙏 Then I can not have to reset every single device I have (I have a lot of IoT devices as well)

I have Android, so could side load

The actual problem is why would my Deci x55 have totally reset overnight??

Every setting has been restored to factory (parental controls, SSID, password, Routing, Static Reservations etc)

As I was looking at every setting in the app, I did notice when I went into the reboot schedule it momentarily showed my previous schedule before updating and then turning it off…

Also interestingly whilst the SSID has been reset to TP-LINK, it is not actually visible (even though it’s not set to hide SSID)

Are there log files anywhere?

Can you guys see logs in your end?

Any help greatly appreciated during this frustrating time

Thank You

  @David-TP Thank You!

I have downloaded a prior version of the apk, and have set up the existing SSID i had, as well as the existing password (Containing spaces) - That worked like a charm!!!

All of my devices are instantly back on the network (Although i do have to fully reconfigure the app with Address resevations, static routes, device & user profiles, Parental controls etc etc..)

Yes as youv'e mentioned, being that i have now factory reset the device, i could not find any logs past the time that i did the factory reset, when i browserd to the IP of the unit in my webbrowser.

I have just submitted an email support and included the system logs as youv'e mentioned. (I also took screenshots of my original forum post, and your last reply, to give them context of why i am sending the system logs through.

It is very weird that it reset to TP-Link (password: 12345678) It seems very generic - Also No-one else in my family would be able to do that! (My kids are far too young haha, and my wife wouldnt know what to do and would have told me.

Based on the google routines that failed to run, and various other home automation logs i've gathered from various devices, i've narrowed the down the timeframe that the Deco Reset occured. somewhere between 4:30am-6am. Whilst we were sleeping...

Yes, now that i know where and how to gather the logs from the app and Deco unit, i will be sure to save them all!

Thanks very much for your assistance!
