sure, tech came by 4/18 swapped modem. 2000 speed...Great until 5:02pm. then back to 330mbs. 

All connectors tight, tech update firmware etc. 

I have 30 years in the telco business and Ill bet 20 bucks the comcast backhaul is out of bandwidth at the fiber transport gear during peak hours causing priority class and Class of service throttling. We can't put 10 pounds into a 5 pound bag.

Thank you Jeff

PS: Im giving Comcast one more try. New store appointment Sunday 4/19 see what they want to do.

The fix, get with the Transport engineers in my area/region. This isn't a drop techs issue. I have another appointment tomorrow at the Williston Vermont Store on Market st @4pm. We'll see what comcast next step will be.

Thank you for posting

Update, so. I went to the Xfinity store. Same questions as the tech visit asked and checked. Change plan to Next Gen and removed VOIP (save $$). Got home, exchanged all PC information with Long Lee(store guru). Yes my motherboard supports 2.5g ethernet. Now, my upload is 100mbs from 331 and my Download wont break 600mbs. 

Comcast will not escalate this to the transport team. This is NOT MY ISSUE, Once Long [Edited: "Personal Information"] ( store guru) say the 1900, 2100Mbs speed test outside busy hour, he kinda disappeared. Next, consumer complaint to Vermont AG office.
