Terrible Upload Packet Loss Providence, RI Area

Hi,

I am experiencing awful upload packet loss that happens around every night around 10pm and does not go away until the next day. During the day, games are playable with around 1-5% upload packet loss. However, like clock work once around 10 - 10:30 rolls around, the packet loss is anywhere between 20 - 100% and anything that requires upload (games, video chats, etc) are literally unusable. I called cox and they said they're having issues in my area and have received other calls about this. I had the tech come to my house and all of my equipment is fine. This randomly started a few weeks ago and has not gotten any better. I was wondering what was being done about this or what usually is the cause/solution and how long it takes to start experiencing high quality internet around the clock again.
