Xfinity WiFi kicks me off Xbox

Xfinity WiFi kicks me off Xbox
Ever since i switched to xfinity wifi ive been having problems with connection all the time and now its getting annoying. Xfinity is cool because i have really good download speeds and all but ever since i had this over at@t ive been getting disconnected
from games left and right and my only workaround is to set my wifi back up and does this many times a day during games where im either doing very good or doing something very important and i lose all my stuff. TLDR recently switched to new wifi never had
wifi issues tried resetting the router didn't work need help.
