Internet Slowness after 8PM

I am seeing throughput issues and drops after 8PM in the evenings.  My throughput is usually 800-900Mbps during the day.  In the evenings, it drops to < 40Mbps.  These are test from the gateway itself, not from devices inside my network.  I also see weird drops on my pings to Google. 

Here is the throughput test from the gateway:

Here are the odd drops on my pings:

Is there someone else from @ATTHelp that can assist with this?  I've provided a fair amount of information in the direct message but have received no response.
