There is an issue with the Cox Panoramic Router/Modem and YouTube. I can't tell if there's a firewall setting or something I'm missing. YouTube videos buffer while using the Cox Arris TG1682G Panoramic Gateway.
I thought at first that Cox may be throttling YouTube so I got the FCC involved. I still suspect it, but haven't been able to prove it. However, when I put the Panoramic Modem/Router in Bridged Mode, and connect my own router to it, YouTube doesn't buffer and videos load instantly. Keep in mind that while using the Modem/Router combo in it's normal Routed/w NAT mode; that speeds were great overall. So it isn't a speed issue. It's YouTube in particular and videos taking 5-10 seconds to buffer before playing, only on Cox's network. This was tested on several different computers, and mobile phones with the same results.
I've changed DNS servers to use non Cox DNS, played in the router settings, turned off TG1682G firewall, etc. I can't think of anything else that could be causing this except Cox doing some sort of traffic shaping/prioritization, or throttling with YouTube coming from their device, or a TG1682G device setting.
Results were intermittent at times, meaning a few times videos would load instantly. That lead me to believe that it wasn't necessarily throttling, but traffic shaping/prioritization instead. Cox has denied those claims as well.
The only constant in all of this is the Cox Arris Panoramic Gateway.
Okay, lets be honest from the start the TG1682G is junk. It should be set to bridge mode and your router should be doing everything else. Hopefully you have a decent router that has better wireless capabilities than the TG1682G. On that note what router do you have? Can't diagnose this with limited information about your hardware setup. Need to include brand name, model and what you use each device for.

I think that is your answer. ISP gateways are junk. Plus your giving away full control over your network and firmware. Suggest changing to a separate modem/router. If nothing else, getting a separate router would allow you to use the gateway in bridge mode.
I have a TP-Link AC1200 Dual Band Router.

Probably an issue with your modem then. Based on how good your router is compared to what the modem provides I would have set the modem to bridge mode and used the wireless router for everything else.
Anyways, get with Cox and see if you can swap out your current modem for an Arris TM3402 eMTA. A Cox employee posted on dslreports.com forum that as of 10/01/2018 the TM3402 is available to everyone on all tiers. This modem was previously only available on the Gigablast tier.
