Question / Help Dropped Frames (Network)

[Rinue]

Hey All,

I've been working on this for months and I can't seem to find what my issue is. I have Fiber from Comcast with an upload speed of 35Mbs. I'm trying to stream to YouTube at 10k bitrate and I've tried Twitch at a 6k bit rate. When streaming my bitrate will dip down to 2k bitrate and will only spike up to my set bitrate from time to time. I've tested on three different computers with using the Comcast Modem only. Comcast has been onsite and tested all equipment and confirmed all equipment and lines are good.

Here is my Log file: https://obsproject.com/logs/1xfb-nZJKWchIJ8T

Any help would be much appreciated.

Thanks for the advice, I tried that with no improvement. Please note I've also tried this on two other computers in my apartment with the same results. The other two PCs have Intel NICs. I wish I had better network troubleshooting tools :( The issue has got to be outside of my area I would assume. I'd rather not try streaming at 2.5k bitrate :(

If it's affecting PCs with other NICs then it's likely either at the level of your switch/router or upstream of you at your ISP.

Comcast had been on site and all they will test is the connection to our Nashville hub. They said the signals are good on my modem and they can't help me. To me this just doesn't add up. Twitch and YouTube should have no problem taking a 6k or 10k stream as that's what they have built the platform for. I'm thinking about buying my own modem and testing it but I don't want to drop $300 on a modem.

So the Comcast modem I have is the TG3482G. I'm going to go pick up a new modem from Best Buy today and see if swapping the modem changes my issue as the Comcast tech refused to do anything for me because the Xfinity speed test worked fine.

I'm back with an update. It turns out the Comcast TG3482G 1G modem has the Intel Puma 7 chipset. The Puma is known to have issues under load and I found lots of info over on badmodems.com - I was able to use the Puma 6 test to find out my modem had the issue. I replaced the Comcast modem with a Netgear CM1000 and everything is working great. The reason why the Xfinity test didn't fail is because it doesn't put a huge load on the modem when testing.
