Frequent disconnects/timeouts

Over the last week I've been experiencing frequent but sporadic disconnects/time outs. Gaming and video/audio calls are near impossible.

Pinging Google's servers (8.8.8.8) shows that there can be long periods with no disconnects (~1 hour) or they can occur every 5-10 minutes for hours at a time. They'll last anywhere from 5-30 seconds, but even up to 2 minutes.

Support has been near worthless. A reset and send me on my way (not before an upsell though!).  I guess they log my issue as 'resolved' since technically I do have internet connectivity when the reset is done.  Followed all the steps on this (https://forums.cox.com/forum_home/internet_forum/f/internet-forum/25345/packet-loss-and-latency) page, but no help.

Any suggestions are appreciated.
