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.

Hello, @user_0e3958 thank you for taking time to follow after the latest visit. If that was just a field technician, they would only be testing the outside line and connection points and if discovering any issues loop in the maintenance or construction teams if they find any noise or anomalies when connected to the outside "tap" (connection point).  

If I'm reading your reply correct, it sounds like the technician wasn't able to find any anomalies, correct?

Yes no issue found. Also, I just looked at my "New" plan. Seems I received a 1gig downgrade. Thats one way to fix the issue.

@user_0e3958 I appreciate the update of not finding any issues during the last visit. From experience, I've seen when changes to the account are done, it will require an order to be reviewed and approved. 

I'd definitely like to investigate the 1 Gig downgrade you had mentioned, are you able to review the email confirmation when the most recent change was done to see what is recapped on the order?

I have had the same thing for over a year;  what search engine do you use?  If your using Chrome GET OUT OF IT EVERYTHING YOU DO IS RECORDED.  I finally figured out this today - I had a password manager on Chrome Filled with passwords I did not create and I went into the setting found all kinds of XCVD! Sorry, anyway my Router stop throttling because I set the setting to no throttle - go figure. Now the internet is fast for me. 

BTW I never used Chrome - maybe once.  I have a iMac and use Safari - and I use straight Google not Chrome because I heard it is sketchy.  Yeah it is, someone had two to four accounts of my 1 account with different passwords - had two admin accounts to my one admin account for my Router - this is why the thing was throttling. its the what do you call it. Hot spot that's what it is.  Shut it down.  No Hot Spot because you have passersby hopping on to your internet and someway get a hold of your information.
