Extreme drop in download speed from 5pm to 6am for last two months

I have been experiencing an extreme drop in my download speeds every night around 5pm and it continues until 6am.  This happens every single day.  I'm currently downloading at 1656 KB/s during the day, I'm able to reach speeds of  100114 KB/s. (On a wired connection). 

I worked with a very beginner technician via chat that basically asked me to reset my router so he could login and check some settings and when he finished he basically set it's a problem with my computer.  I had to go back in and reconfig my router properly after he was done.  It's not my computer, I'm transferring data from my computer to my internal NAS at the same speeds I have always been. 

It's seems impossilbe to get a skilled technicain on the phone to assist.  I need to get the speeds I pay for or I'll have to start looking for another provider.

Your number are not clear to me.  KB or Kb.  KB speeds are 8 times slower than the speeds normally advertised, 8 bits (b)being in a byte (B).  And you did not specify what plan you are on as 100114 KB/s not matching any of them and being higher then all but a couple of them.  e.g 75/75 is slower.

Only wondering as I am just a peer.

Hi TNS,

Thank you for taking the time to read my post.

Sorry, I added on to another thread with more detailed information.  I have the 75/75 plan and the stated "KB" is not a misprint.  I'm flying during the day and barely able to crawl at night.

In the other thread I posted results from the NDT.  I've now forwarded everything to the Verizon Tech that reached out to me via this thread.  But here's the information I posted in the other thread, just for continuity and some more context.

Thanks again!

The speed tests always seem to come back fantastic 83/91.  It's when I start to download large files and watch video that speeds drop.  I've run tests using the same files during the day and night and there's a huge difference in speed.

 

Here's the results from the NDT.  I actually ran the optimizer and then ran the NDT to make sure I had ideal settings.

 

I'm curious about the statement "This connection is sender limited 90.84% of the time".ta.
