Packet loss and disconnects with XB6 (TG3482G) gateway on ethernet connection

I've been having issues with my TG3482G modem/router combo disconnecting frequently. I pay for the 1gb service and have been dealing with this issue for months now. I have a wired connection to my gaming console and even that has connection drops 2-3 times an hour. It's ridiculous. 

There are no coax splitters going to my modem. Just a single coax from the wall to my modem, then an ethernet cable (cat6) to my PS4 Pro. 

I searched through the forum here, but most posts related to the XB6 are locked. Has anyone else had this connection drop issue? How do I fix this?
