Model: Deco BE25  
Hardware Version: V1
Firmware Version: 1.1.0 Build 20250718 Rel. 40387

Networking Setup

 

1Nos - Deco BE25 in Router mode

1Nos - ISP Router

1Nos - Desktop

 

Deco BE25 v1 1.1.0 Build 20250718 Rel. 40387


ISP Router -> Deco BE25 (Dynamic IP) - ETH Port 1

Deco BE25 -> Desktop - ETH Port 2

 

As soon as the internet drop ethernet port 2 stops working which is every surprising as Intranet should keep working. Never have I ever faced a similar issue with any other deco series products. Please guide & help resolve the issue!

 

Thank You

Hi, the feature of fixing the WAN port is on the plan, but there hasn't been further news on when the specific firmware will be released for Deco BE25.

Best regards.

Hi, can I have the model number of the ISP router?

When the internet dropped, would there still be an IPV4 address on the Deco App>More>Internet Connection>IPV4?

Can you also send an email to support.forum@tp-link.com?(Please add the forum ID#851090 in the subject.)

 

Thank you very much.

Best regards.

  @David-TP 

thank you for the response

 

"the model number of the ISP router?"

Ubiquiti UCG-Ultra Cloud Gateway

When the internet dropped, would there still be an IPV4 address on the Deco App>More>Internet Connection>IPV4?

Two scenarios here

  1. when connecting to router directly the IP will be there
  2. however I also did a unplug test - in that case the Intranet should work - problem is the dynamic WAN port detection

 

will send email too .. do you have any beta firmware which I can test to patch this issue?

Hi, thanks for the quick reply.

There hasn't been a beta firmware that allows fixing the WAN port on the Deco BE25.

For your situation, as long as the main Deco BE25 is physically connected to the Ubiquiti UCG-Ultra Cloud Gateway, the connected port would be the WAN port, as the DHCP server on Ubiquiti UCG-Ultra Cloud Gateway should continue assigning an IP address to Deco even though there is no internet access.

Best regards.

by when can a patch be expected?

also, has it been registered and acknowledged by the firmware dev team?

Hi, do you sort it out? This is one of the issues I’m getting since upgrade from M5 router. I’m not sure what is causing the issue but while on this new be25 my tv is unable to reach internet randomly neither WiFi connection works for this device while this happens. I’m considering to return the device.
