Spotty internet and Packet loss at the same time every night.

Every night at around 8:00 PM EST to roughly 10:00 or 11:00 PM EST my connection begins to experience high pings, jitter, and packet loss but the download speed remains relatively fine. This randomly began happening out of nowhere and so far I have been unable to determine what's causing it. There is nothing else sucking up bandwidth in the house that I am aware of and I'm not doing anything different than I was an hour ago. This has been happening like clock work all week in this area. I've wondered if it could be my outdated modem? I don't know how to interpret any of this but here is the signals page. Does anything jump out at anyone? Thanks in advance for any support!
