Cox Cable usually only offers 10mb/s upload, so it doesn't take much competing traffic to cause congestion. And then as the troubleshooting guide points out...
- I recommend starting with figuring out how to do real-time bandwidth utilization monitoring at your ISP connection level first (which you could do at cable modem or router (which usually has more info)), then on your machine
- Then I'd test, outside of streaming, that your Internet connection can sustain volume upload bandwidth. And if you run into trouble at this stage, be sure to test with a different clean/known-good machine.
- *IF* sustained uploads (not streaming) work to other targets, then time to test whether issue is
- Traffic to and/or your streaming target (try an alternate stream host/CDN?)
- Your PC (could be recent OS, driver, or security software, or anything else running in background interfering)
- or any number of other issues
For months (last fall) we had an issue with Facebook regularly briefly dropping frames (like 2-3 seconds) at least once per 1h+ streaming session. Local PC was not overloaded, Recordings were fine, etc. And then the issue went away... the joy of using a free service
