Note:
1. Please be sure you have read the Beta Test Agreement before upgrading the Pre-release firmware!
2. It is recommended that all Decos in the network be upgraded to beta firmware.
3. Please also check whether there is a firmware update for the Tapo device in the Tapo APP. If so, please update the Tapo device to the latest firmware.
4. How to update the satellite Deco units:
When the satellite Decos are offline, they may not be successfully upgraded through the Web UI. In this case, it is recommended to upgrade according to the following steps:
- Please temporarily power off most of the smart home devices and wait for the satellite Deco come back online.
- Once all the satellite Deco units are confirmed online, try upgrading to the beta firmware again through the Web UI.
-If the main Deco and satellite Deco units are on different models, you could also update the satellite units individually through its IP address.
- After ensuring that all Deco units have been successfully upgraded, power on the Tapo devices again and observe if the issue is resolved.

Hi, Thanks for your time and patience.
I'm afraid Deco X50-V1.2 might still need to be on 1.4.5 for a while. There hasn't been any updated news about the next official version.
Best regards.

Hi, Do you mean the "OFDMA/Mu-MIMO" on/off toggle on the Deco APP?
It isn't added to Deco X50_V1.3. Only certain models, such as Deco X90/XE75/75 Pro_V1 have added this on/off toggle-(https://community.tp-link.com/us/home/forum/topic/655004?replyId=1352020).
The OFDMA/Mu-MIMO is enabled on Deco X50 by default.
Thank you very much and best regards.

I installed the firmware 1.4.5_build_20241021_Beta for Deco X50/Deco X55_V1.2
The problem of satellites that were offline but with green LED, now seems to be solved.
However, there is the problem of devices connected to the IoT Wi-Fi network that are offline even if working.
This problem was solved in the previous beta.
The problem has reappeared with the official 1.4.5 firmware and is also present on this beta.

Hi, Do you mean the "OFDMA/Mu-MiMO" used to be added to Deco X10 before?
I didn't realize it till now as it hasn't been mentioned anywhere but I do know that this on/off toggle did exist on certain models. If any model doesn't support this toggle in a mixed Mesh system, it will eventually disappear from the Deco APP.
Thank you very much and best regards.

@David-TP This particular problem has cost me several hours/days to resolve (on my own, because Support didn't pick up on this being the issue). I'm glad I eventually found this article - it helped a little, but it still wasn't perfect for me. Deco's would drop offline after a few hours/days instead of always being offline.
It's ironic that this bug affects networks with a lot of tp-link devices. It's a bug introduced by tp-link, and it's affecting customers with a lot of your products. I've had many problems over the years, but this one is the worst, and the final straw.
I've now bought whole new WiFi mesh system from a different brand (at great expense) to replace my Deco network. I had the replacement setup within minutes and it's been amazing so far.
My advice is for tp-link to get this sorted ASAP before you lose any more customers.
