YouTube Performance issue.

[TroutWA]

So, this one is a strange one.

A long time user of Untangle, I decided to give OpnSense a go. Part of the reason was that the hardware now about 6 years old (a Chinese unbranded industrial PC with an intel 2 core processor and 4 ethernet ports)

I bought a GMKtec AMD Ryzen 5 7640HS Mini PC--NucBox M6 Ultra with 2x 2.5G Realtek ethernet ports

It all installed fine once I loaded the Realtek Drivers. Once I got it up and running I got download speeds of 960M and upload of 46M from a 1000M/50M link, so really happy. But I noticed that YouTube video struggle when I am viewing on my PCs. Mobile and TV are fine. It gets to the point that that it buffers even a 240p stream.

Somewhere I read it was an issue with OpnSense and the new Realtek cards.

So I loaded up PFsense on the old appliance and swapped it out (to avoid down time on the home network)

YouTube worked fine, network overall speed dropped 250M/30M.

Next, I got my new GMKtek loaded PFsense (struggled a bit with the drivers much easier process in OPNSense) and swapped it again and I get the same problem I had with OPNSence.

So yes, on the surface it does appear to be hardware related but why does it only affect YouTube on PC. Is there a fix other than swapping hardware. I am contemplating getting one of the Deciso Appliances but that probably won't happen for a few months, and the network cards are inbuild on the GMKtec so I can't swap them. Any idea?

Thanks,

Diego

Your up- and download speeds differ "bigly" - maybe try traffic shaping (see https://forum.opnsense.org/index.php?topic=42985.0, #26)?

I wouldn't expect any issues related to asymmetry, with that much bandwidth. Any individual video should only run a few Mb/s. GoogTube is going to be QUIC (UDP) anyway, unless UDP 80/443 is blocked. I'd tend to look at the affected PCs - anything unusual about them.
