Hello.

I upgraded my 3 Deco P9 yesterday to 1.3.0, and my home network is a chaos, completly unstable!!! Never saw any warning in the app about I need to revert, is it possible? Or I must dump the whole system...

Hi, thank you very much for the feedback.

Can you add more details about what happened after the firmware upgrade, such as the powerline backhaul no longer working?

Could you please refer to this link to check which one is similar to your current issues:

Fix unstable connection when connected to the Deco network

 

By the way. may I know how long you've had the Deco P9?

After the firmware upgrade, if you haven't reset the Deco once, it is also suggested to factory reset the Deco by holding the reset pinhole for 1s and set it up again from scratch.

 

Wait for your reply.

Best regards.
