Constant High Ping and Packet loss

Hello everyone, I got xfinity installed in my home about 3 months ago and its been pretty bad so far. Every online game is nearly unplayable as my ping spikes to over 300ms and there is constant packet loss. It seems to be a bit better in the early hours of the morning (2am, 3am, etc) but other than that its tough. I swapped over from ATT DSL and that was better than this, though the download speed was worse. I have access to 10.0.0.1 and can post screenshots of anything. Any help is greatly appreciated as I love the download speed and would like to keep Xfinity. Thanks!
