@Alc0708

Thanks for the update.

Currently, there is no new firmware available for Deco X60.

I have seen that there are also Deco M9 plus as well as MR600 under your TP-LINK ID, could you please send me a picture of your network topology, such as:

Cellular Tower))(( MR600---main Deco X60, then wirelessly connected to the rest of the X60 and M9

Did Deco X60 work on the wireless router mode or access point?

Did you have any wired computer to test whether the Ethernet connection dropped the internet as well?

Would turning off the Mesh technology on the mobile devices help stabilize the connection?

@Alc0708 

Thanks for the confirmation.

What are the devices that are frequently disconnected from the internet service?

Here are some suggestions for you:

1. Please turn off the Mesh technology for these mobile devices on the Deco APP.

2. Since 2.4ghz is easily affected by wireless interference, please try to turn off the 2.4ghz on the main network.

3. Reserve the IP address on the Deco APP for the mobile devices.

Did you have any wired computer available for testing whether the Ethernet connection is stable or not?

Hi, I might need to follow up on your case by email, and please have a check of your email box later.

By the way, What are the devices that are frequently disconnected from Deco?

"It is stable like 4 days then when i try to connect the deco unable to connect the my network", were you trying to say the device could not connect to Deco's Wi-Fi network？

Please also try to turn off the fast roaming/beamforming on the Deco APP.

Thank you very much.
