If you order the 960mbs or higher service, it will come with the 6500 SmartNid that has one 10gbe port. Lower speeds will be the 5500 model with 1gbe ports.
My Xfinity price-for-life just increased...Now I have to wonder whos "life" they were talking about

The life of the CEO's hamster?
I guess I will go with the 500mbs Quantum for $50. It is far more bandwidth than I will ever need. At least it comes with WiFi 7 main and one pod at no extra charge. $50 is more than I want to spend but Xfinity NOW is "now" off the table. I am looking forward to single digit latency and jitter even though I doubt I will notice it.
