[RFI] Xfinity X1 service

[Alan NV8A]

Roger:

We have Charter -- with a plan that "guarantees" 18Mbps down and often 
far exceeds it, but still offers only 4Mbps up and usually exceeds it by 
just a smidgen. I see Charter advertising only 66Mbps down and 4Mbps up 
for their "Business" service. How do you have a 100Mbps download service 
with Charter, and what is your upload speed?

(Our son's Internet service in VK3 is 100Mbps up *and* down.)
