Issues with Comcast throttling. Possible shenanigans

Back last year my Comcast issued modem died. It was a Ubee U10C035. I had no problems with it until it died. I went to return the modem to my local office and get a replacement but now they offer the Comcast branded wireless gateways, that cost 15 dollars per month. I opted out of getting one and went to Walmart and bought a Motorola Surfboard SB6121 and had it activated once I got home. Everything has been working fine up until October. I am also using OpenDNS due to the fact that the DNS servers on Comcast suck. Constant outages but with OpenDNS there is none.

My router is Netgear N750 WNDR4300

I have had nothing but problems ever since, it seems like everything is throttled these days.

Netflix = Throttled
Hulu = Throttled
YouTube = Throttled
Steam = Throttled

Also my data usage meter is gone. They want me to call a number to get it reactivated but everytime I call it I get put on hold for over 30 minutes.

I am at a loss. All my devices streams ok (most of the time) YouTube mobile however wants me to force HD. But my PC using a wired connection does not stream properly 80 percent of the time.

Could my ethernet adapter be configured wrong?

I also have a pretty beefy connection so not being able to stream YouTube in HD makes no sense.

I have never been this pissed off as I am now with Comcast, YouTube, Netflix, Hulu, etc.

Remember when video streaming would buffer the entire video all at once? I miss that.

Does anyone have any advice for my problem?

This is just a wild idea of mine I'm probably executing soon, but a custom VPN server on a VPS in a reliable datacenter nearby should prevent all IP-based throttling.

I would highly recommend a vpn. It can speed up you traffic to popular website like youtube, netflix, etc. as well as encrypt your traffic so it is private. Logan and Wendell explain it better here though.

Can I install that onto a router? They never did a video explaining how to.

If your router supports DD wrt then definitely. Otherwise it might be an option in settings but router dependent

I watch YouTube on my tablet, phone and PC. Hulu and Netflix I watch on my TV using my Samsung Home Theater System. If I could get this to work with my router it would be awesome.

Before I get to using a VPN I will swap over my DNS servers to the vanilla settings then get my usage meter back. It will be well worth the wait in the end I hope.

You might also look at using a vpn on one device -before you invest time in doing this at the router level

It definitely is shenanigans at my ISP. The throttle is not a problem right now, due to the fact that it is the last day of the month.

If I knew how to fill out a complaint with Comcast on the FCC website I would.

Comcast bills you when you go over the data cap so throttling makes no sense.

They're probably throttling because they want you to pay more and because their network is so bad it couldn't actually handle the speed they sell if everyone wanted to use it.
