Netgear CM1000 / Nighthawk XR500 Issue

Hi there, I am having an issue with either my CM1000 cable modem or XR500 wireless router. I purchased both of them just yesterday. I play Overwatch and noticed two times during a two hour duration that I lost connection. I was able to set up the modem and router fine, the firmware updated fine, and I went through each setting on DumaOS after reading all of the guides on the DumaOS site. Comcast is my ISP and I get around 180 download and 15 upload speeds. My gaming desktop is connected by ethernet to the XR500. 

I used to have the C7000 modem router all in one but experienced severe ping spikes, in-game lag, and disconnects which is why I went with the CM1000 and XR500. The ping spikes don't seem to be an issue anymore which is great, but the disconnects are a concern obviously. The first time I disconnected on Overwatch I decided to run a continuous ping. I had in-game lag, went to my continuous ping and noticed the request timed out one time and one packet was lost. I reviewed the modem and router logs. I didn't see any warning or error logs for the modem but I did see some odd logs on the router. I attached an image showing the router logs. 

I talked to Comcast a couple of times and they don't see any issues on their end. Please let me know your thoughts on this, I appreciate it.
