So .. you are pre-releasing 1.2 before releasing 1.10 which is already in BETA / Pre-release ?

 

are you going to release 1.10 at some point ?

Hi,
Even for the same Deco model, different hardware versions may have different firmware versions. The firmware posted here is intended for the Deco X50/X55 V1.2 and is not compatible with other hardware versions, such as the Deco X50 V1.0.
Best Regards

I installed it 15 hours ago. 

I tested the 3 and the 6, and they seem to work properly. 

No problems so far, running everything great.

Installed the beta version on my other house in a second unit, where main deco is be65 firmware 1.3.3.

After sometime the x50 unit become instable, keep disconnecting the connected devices, and Internet speed on devices connected to this unit are extreme slow.

Devices connected to be65 have no problem.

Hi, 
The latest firmware for the Deco BE65 V2 is v1.3.5. Please try updating the main Deco's firmware and test whether the Deco network is stable.
 

Please confirm the following information if the same phenomenon occurs.
  1. Please describe your network diagram. How many Deco nodes do you have, and how do they connect to each other?
  2. What's the LED status on the Deco X50 when the clients connected to it drop the connection? Do the clients drop the connection at the same time?
  3. How far between the Deco X50 and the main Deco? Are there obstacles in between? Please go to the Deco App > tap the Deco X50 and click it again to see the signal strength it obtained from the main Deco.

 

Best Regards

I tried the firmware recovery process, and now the X50 seems stuck. The LED is yellow.

Hi, 
Please factory reset the Deco X50 and check whether the LED status changes. If not, please refer to "Method 2" in the instructions below for troubleshooting. Please note that for Deco X50 V1.2, you must first recover to this specific firmware version, then update to the official firmware version on our official website.

I am having the same problems with 2 x BE65 connected by ethernet and 1 x X50 connected to the main BE65 by WiFi. When I updated the X50 v1.3 to 1.8.4 I started having all sorts of WiFi connectivity problems across all 3 nodes.

 

Dragged out a X50 v1.2 that was still on 1.4.6 to replace the X50 v1.3 and everything works perfectly.
