patrick....IT WORKED! that's the issue, the new modem's wan/lan port is just for fiber. after connecting to an ethernet port it worked. thank you for your help

Patrick, I have tried using the dynamic IP selection but that didn't help. I'll try to re-establish the deco wifi using an ethernet port and see what happens.

New user here. Used the deco app to setup the wifi and all went well but wifi unable to connect to the internet. My internet is provided by Centurylink via dsl. The modem is a C4000BZ. Verified that...
