So hoping for some help here with my New TP link router. Every device I have (laptop, TV, Xbox) connects fine to get internet access. However I'm having issues connecting Alexa echo, so tried DHCP, static IP, putting that IP in a DMZ.. and Alexa just won't connect to the internet.. Alexa does connect to the router, but can't reach the internet, even when all other devices are working fine. Although my Xbox one states a Double NAT issue.. i suspect there is something obvious i'm missing... but what!?

Any help would be apprciated!
