Recently purchased a G36 and upgraded my Wi-Fi speed thru xfinity. Has worked out great for all my other devices (multiple TVs, laptops, tablets, etc) but my Xbox specifically struggles to connect to the Xbox Live service. The Xbox shows as connected to the internet but fails when trying to connect to the Xbox live service after multiple years of success usage. It’s an Xbox One from ~2015 if that matters.
I’ve tried contacting Microsoft and they’ve kept pointing me back to my router. The error message varies on the Xbox but typically shows as “UPnP unsuccessful”. I’ve tried messing around with multiple settings on the SurfBoardCentral app. Obviously enabling UPnP, changing various security settings based on other posts, adding Port Forwarding, etc. What am I missing?
