@TP-Link I have the same problem, I have bought a third deco to expand my internet connection, and is completely useless, is taking connection form the original source instead from the nearest one....

@TP-Link it was a modem-router combo. I have opened the same port but for the deco is connected to the router and it worked, thanks for the response.

@TP-Link Deco I'm not able to open a port, I have tried the following steps: https://www.tp-link.com/us/support/faq/1797/ but when I check if the port is open it says is closed. I really need to open...
