Troubleshooting Ethernet not working on deco?
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Hi there
I've just bought a 3 Deco M5s. I've installed all three.
One with the ethernet cable plugged into my router, one in my study downstairs, and one upstairs in my room.
All wifi is working fine, however, in the upstairs one, i've plugged an ethernet cable from the Deco into my ethernet switch, which in turn goes to my computer, but there is no connection at all. it says no internet..
how can i fix this?

Hi, I think you might locate the problem.
Please disable the IPTV under Deco APP>More>Advanced>IPTV/VLAN to see whether the issue could be solved.

@DanielSweet I have not found any serious issue but still think that bill checking might be cause.

@TP-Link One simple question
X20 Deco
Why "Main" Deco have 2 UTP ports since "without internet service" both ports become WAN ports ? This make no sense at all.
User should can setup (on choice) which UTP port is WAN and which is LAN ... is about few line of code, why is so hard to fix this stupid problem ?

Welcome to the community.
Because the Ethernet ports on Deco support WAN/LAN auto-sensing. "Without internet service" might not be so accurate here and It should be "ISP modem could no longer provide an IP address to main Deco". So sometimes, even if the ISP service failed, the modem kept providing an IP address to Deco, Deco would still have one WAN port, and another LAN port. It is one of the unique working mechanisms of Deco and one benefit is that you don't need to replace the Deco if only the previous WAN port is broken since it has an alternative WAN port.
And the real cause here should be why the ISP modem suddenly failed, not why Deco is WAN/LAN auto-sensing.
Thank you very much.
Best regards.

My setup on Main Deco, I think like more users from here is:
- One LAN port that become WAN for internet provider cable
- One LAN port is for one Switch (in my case with 24 ports)
Problem:
When Internet provider fail or something else happen with internet cable, any device connected on DECO wirelessly can no longer connect to any device connected to the Switch through cable. When internet service working again, everything back on normal.

Hi, you are right and what you have summarized here is exactly what we have received from user feedback.
The design of WAN/LAN auto-sensing would not be changed in the short run but this mechanism needs to be smarter which is also what the senior engineers try to optimize gradually .
Best regards.

Hello all,
I had the same problem and this is how I SOLVED it!
The problem is with DNS. Use the default TP-Link DNS instead of your ISP.
On your Deco app, go to More --> Advanced --> IPv4 --> Click Dynamic IP --> Uncheck Obtain DNS Automatically.
For the Primary DNS, use 8.8.8.8
For the Secondary, use 8.8.4.4.
After you save, almost immediately, the second ethernet port will work. If your PC still isn't getting internet, just do an ipconfig/all and make sure your pc is getting the 8.8.8.8 DNS from deco.

@Sheikh1 Hi, I am having the same issue. Just bought X20-DSL two days ago. This is definitely a Deco problem. I still have my old router when I connect it to all the same ethernet cables there is no issue, but when connecting with Deco ethernet is not working. I have all 4 Deco ports connected to my foxtel, fetchtv, POE, and Eufy security hub. The 1st night I couldnt get Eufy Security hub working over ethernet, but got it working on wifi... and just thought it was the Eufy playing up.. Tonight Foxtel and FetchTV have stopped working over ethernet... if I switch to wifi they all work, but it is frustrating... I want to be able to use the 4 ethernet ports. I am not using IPTV, I have a fox lately satellite box that has an ethernet connection for streaming in addition to satellite, and I have the FetchTV mini box which streams. Please help resolve.
