Problems with Speed/Latency/Trace Route/Dropped Packets/Outages

I have seen many posts about people having multiple problems as we approach the Flip of the switch for many for X-Class. I myself have had Comcast since 1998 when they installed 1mbps service here in the Twin Cities. I have seen many upgrades over the years and been through all the probs. But I am seeing so many people with the same problems and no answers. I had a tech out to my House this week and he checked my signal which came back at 1.8 GBPS and the max plan and speed I can get are 1.3 GBPS with 40mbps up. I have to wonder if the back end is just about complete and the front-end software and backend signal are having conflicts. So, I am curious to see what people are running.

What I want to ask is for those having problems who have an XB8 gateway as that is the only Xfinity supported Gateway. And then what software is the gateway running?
