I've had Fibre for almost a year now without much issues. This past week whenever someone in my household is streaming Netflix, youtube, etc, I get big ping spikes / go red bar on my xbox one. This wasn't an issue prior to the last week. When I run a speed test on my console during these issues I get roughly 70mb down and 20mb up. When I run a speed test when nobody is streaming I get 100mb down/up. I've got a static IP set up for my xbox, along with all the necessary ports forwarded to get a proper NAT set up. All devices that stream/play games are on wifi (unfortunately).
Any suggestions? Nothing has changed to my knowledge.
