Xfinity 1Gig Modem & A Ticket Question...


A New installation was done today, When i did the order, I was recommended the SB8200 Modem and that i should not worry about the phone (If calls are really recorded, its there! 8-))

Anyway, I was told i need to take the Xfinity Modem for now, Took it, I was surprised i got XB3 and not XB6 (Not sure if XB3 can get to 1Gig) - Any ideas?


Also with the XB3 we never managed to pass 50Mbit/s download, 2Mbit/s Upload, After 3 modem replacments,

The guy decided there is a capping problem in my outside box and it need to be replaced (case JB19731047)

any idea about such thing ?

Xb3 can’t Handel gigabit speeds.
you would need a XB6 modem which has to be tech installed as far as I am still aware.
