I have my Deco X55 connected to my T-Mobile 5G gateway via access point mode. It's been fine for a year since I've gotten the Deco mesh system. But starting about 2 weeks ago, overnight all of my devices lose connection to the internet. They're still connected to the Deco devices, but there is no connection to the internet. I have to power cycle my T-Mobile gateway to get things back to normal. I'm not sure if it's the gateway or the Deco. Any thoughts?
