Periods of high latency & extremely slow speeds

Problem seems to have started popping up last tThursday, but since then my house seems to have periods of time where the network speed slows the a crawl and I'm barely able to use the network (and definitely unable to run any multiplayer games). I've tried a bunch of different simple fixes but to no avail, so I'm at a loss on what I should try next.

Setup information:

Modem/Router: AC1750 Wifi Cable Modem Model
Wiring: Underground, resedential neighborhood
Affected Connections: Wired and wireless
Normal Speeds (wired): ~50 to 100 mbps download and 30ish upload
Speeds during a bout of slowness: ~0.3 mbps download and 0.6 mbps upload

What I've tried already

Resetting the modem/router (on my end)
Factory resetting the modem/router , netgear admin page shows connection is 'good'
Unplugging the modem/router and waiting 3-5 minutes to plug back in
Resetting the modem/router (on coxs end)
Disabling wireless and testing only my wired connection

Useful info?

I noticed in this thread a guy says anything over 1-2ms on a ping to 192.168.0.1 is a problem, and here is my ping output:

Here is also my connection information which I grabbed from my netgear admin panel:

Any ideas on what I should try?
