Using Windows 10 (v1709) and Chrome (64.0.3282.167), when I watch a YouTube video, my Internet connection works for approximately the first minute, then drops out.
In more detail: I can watch a video for a short period of time (typically anywhere from 30 seconds to 2 minutes), then YouTube's "stats for nerds" shows the connection speed dropping from 30-40MB/s to around 100 kB/s, and DNS lookups start failing. Chrome gives me the dinosaur for any other website I try to connect to from that point on, even if it's not YouTube. Doing things online without visiting a YT video has no issues and the connection will stay up for as long as I want.
My connection is set up such that my PC is connected via Ethernet cable to a first-level access point on my desk, which is connected via Ethernet to a cable modem/router downstairs. Both cables test good for continuity. Rebooting either my first-level access point or my computer fixes the issue, but it's a pain.
Using Ubuntu instead on the same machine (dual-boot), I have no issues.
I've had a look around to see if there are any known fixes for this, but it seems most people having this issue had it in 2013 and the problem was AVG antivirus trying to be more-than-antivirus. I do not have AVG, nor is it 2013.
I am confuse. What can I do?
