Hi. My brother and I, have comcast for several years and never had a problem, now the xfinity wifi that we use, is just getting terrible and terrible at our area, my zip:02150, his:02149, is there a reason for it?, we pay a lot money for this services, and I honestly use more xfinity than the wired internet, so I really need working, please see if you guys can fix this.
Are you talking about your home WIFI or many of the Xifnity WIFI hotspots in your neiborhood?
WIFI signals are subject to interferences many times outside of your control. All it takes is a neighbord turning on his turbo router to mess u up. If at home, there is nothing, nothing better than ethernet.
