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, 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.
