Solution Satellite Deco Units Work Well but Display Offline on the Deco APP
This Article Applied to:
Deco M4/M5/M9 Plus, Deco X50/Deco X50-Outdoor etc.
Phenomenon Description:
The satellite Decos are solid green(or white) and work well but they are displayed "Offline" on the Deco APP.
Available Solutions:
-
The official firmware will be released later to optimize this issue.
-
Based on the feedback we've received, the majority of issues are related to the abundance of smart home devices, particularly Tapo smart devices. To address this, we recommend installing the following beta firmware as a temporary solution:
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, Sorry for the delay.
I think it is worth a try to install the beta firmware. It will help with the client list issue.
As for the Deco X55_v1, Are you still unable to update to the 0816 beta here? What is the current firmware version of Deco X55_V1?
Wait for your reply and best regards.

Hi, Thanks for the update.
It should also improve the network stability so the Deco APP could receive the correct response code and display the correct status.
The new official 1.6.4 Build 20240718 Rel. 76925 hasn't added this fix yet. It is expected to be included in the subsequent version following 1.6.4 if all goes as planned.
Thank you very much and best regards.

Hi, since you commented on this post, do you mean the satellite Deco M4 units are solid white, connected via Ethernet cables, but Deco APP reported they were all offline?
Would the mobile devices still get internet connection from these "Offline" Deco M4?
Wait for your reply and best regards.

Hi, Thanks for the update.
Since you are on the 1.7.0 beta, would you mind factory recovery to the 1.6.2 beta in the first post to see whether it helped:
I just updated a new beta version for Deco X10_V1, Please also test whether the beta firmware helps:
| Deco X10/X15/X1500/W4500_V1 | 1.1.5_build_20240910_Beta |
Wait for your reply and best regards.

@David-TP After downloading the file according to your instructions, I see that the Deco X10 is updated but the mesh does not connect to the Deco M4 v2 and the main router is disconnected. It's an old version so it's not possible to update... Since I was using X10 as the main router and M4 3-router backhaul was connected by meshing, today it's not possible. I opened Deco X10 and set up Deco M4. When a device goes offline after a while when that device goes online or connects again, it takes a lot of time for IP binding or access is denied. Big brand may give more support to customers but physically I am disappointed.
