Packet Inspection causing issues using Nvidia Geforce NOW on UVerse Fiber

I spent a long day yesterday testing why I was getting stuttering and cutting out on my 1GB AT&T UVerse Fiber line when trying to play games on Nvidia Geforce NOW.

Used multiple machines, multiple monitors, multiple quality settings, reconfigured my network, plugged in ethernet, moved around the house, etc etc... Nothing would get rid of the stuttering on Geforce NOW, however I wasn't experiencing the same on Google's Stadia or any streaming video services.

Finally, getting desperate, I decided to try connecting via Wireguard to a small server host I have within the same state as me. Suddenly, boom, no more problems, perfect clarity even at max settings. No more stuttering no more audio cutouts. I was adding extra hops to my connection to Nvidia's servers, but my quality was actually better?

This reminded me of issues I've had with corporate VPNs in the past and AT&T's Internet services doing packet inspect for some reason causing a lot of latency issues. AT&T inspects packets to try to detect UVerse TV traffic or something? I think to keep it from counting for your bandwidth usage? I'm not sure I've ever understood the reasoning for this entirely.

Is there some way for me to turn this off of my internet service line? I'm never going to pay for UVerse TV, and checking for it is degrading my internet in multiple use cases to the point of REQUIRING me to use a VPN to get working service.

Let's see if we can get your streaming quality to improve, @dillius1024

 

We recommend setting up port forwarding. This is generally helpful when trying to use a streaming device, like the Nvidia Geforce NOW. Just select your model of gateway from the dropdown menu and follow the instructions listed under Set up port forwarding.

 

Please let us know if this helps!

Raiden,

Nvidia Geforce NOW doesn't have any ports it requires be forwarded according to their documentation... I'm the client, not the server in this case. Does AT&T have documentation specifically on this service?

Thanks for letting us know, @dillius1024

 

If port forwarding is not available with the device, you're going to need to reach out to the manufacturer for support, or use our HomeTech premium service. They have more expertise when it comes to 3rd party equipment. 

 

If you have any other questions, please let us know! Thank you for contacting AT&T Community Forums!

This is not a Device, it is a software program. It does not LISTEN ON PORTS. I don't think you understand what I'm talking about at all.

I don't know what I expected coming to these forums, just hoping really to let other people know who run into this problem how they can work around it I suppose.

Hey man. Found your post because I've been dealing with this exact issue for ~2 years now. AT&T is upgrading my neighborhood currently from VDSL2 to fiber to the home. But we live very close to the VRAD and get the 100/20 VDSL2 service. 100 Mbps down 20 Mbps up should be plenty of bandwidth for GFN. But whenever I run the network quality test in the GFN app it always fails due to the packet loss percentage being too high.

A screenshot from one of about 10 tests I did just now, packet loss is always above the 2% required, usually testing at 3%-6%. The other metrics always come out perfectly fine.

I did manage to come across a different test that showed something interesting. Doing a tracert to a GFN server IP address is interesting but obviously dose not help much since it's well... a tracert and ICMP packets. However I came across this site https://packetlosstest.com/ that is a far more interesting test.

I discovered that using the sites GFN 1080 game streaming pre set and running the test over and over, my jitter is the issue. One test it can be 1-2MS the next 70MS+

Example here are two tests on the site I ran just now. Back to back.
