Packet Loss at regular intervals for a week straight now

I am regularly experiencing packet loss to multiple servers/services and have been every day for the past week. It happens around 5 PM Pacific time and dies down around midnight. It does not happen outside these hours, I am home all day every day and have been monitoring this regularly since I began to notice the issue. I understand that these are "peak hours" but that should incur some additional latency if anything, not packet loss. And like I said, this only began last week and I've been at this residence for almost 2 years.  Attempts to resolve so far:

 

  1. Restarted my router and modem
  2. Tried my PC directly into my modem, bypassing the router
  3. Tried an entirely new modem
  4. Changing to Google's DNS
  5. ipconfig release/renew nonsense
  6. Had a tech out to my house who ran a new line from the underground box in the sidewalk through to my house. 



    I have run several traceroutes over the past several days and have been keeping PingPlotter up in attempts to see where the issue is beginning. For the first several days, I only saw issues on be-322-rar01.hayward.ca.sfba.comcast.net (IP Address 162.151.79.125) and be-399-ar01.hayward.ca.sfba.comcast.net (IP Address 68.86.143.89). However, lately I'm seeing loss on several nodes. 

I don't know if those IP addresses farther down on this image are owned by Comcast, but I have other PingPlotter charts that show issues on several of theirs. 

I realize that I failed to capture the final destination IP in this second image (it's from yesterday) but I was observing loss in the final point just like in the first image. I understand that packet loss in the intervening space between the source and destination are not necessarily an issue, so I wanted to address that to avoid any comments to that effect. 

I have been on and off the phone with support for the past week. I won't waste time complaining about how unhelpful they have been besides to say that they have gone through all their basic troubleshooting steps from their customer support guidebook or whatever, and those obviously didn't help. I have requested many times to be escalated to someone with networking knowledge but have not gotten to speak to anybody who even understands what "packet loss" means. 
I'm really begging for help here. I work from home and make a little money with online gaming content on the side, and this has completely prevented me from doing the latter for the past week. The tech that came to my house on Sunday, June 26 said he emailed his supervisor about my issue after determining there was nothing wrong with my local connection, but obviously I am not included on that email so I don't know if it's going anywhere. 

I am happy to provide additional screenshots of traceroutes, etc, whatever can help someone help me. I'm looking for some kind of advanced troubleshooting help. If you need any additional information, please ask. I really need this fixed. Thanks.

Additional information: I'm just going to provide all my modem dashboard info here in advance since I might get asked for it.

Another update: It's not just me. My friend who lives  2 miles away from me is experiencing the exact same thing. This is 100% a Comcast issue. Please help.

The tech's supervisor called me and stated that they resolved the issue. They had a bad NIC somewhere in the pipeline.
