As per title. I'm on Fibre 200/20 - running FritzBox 7.01. Never had any issues until now. I'm running on Ethernet cable.
Speedtest normally 200/20, but drops to 6Mbps DL and then gets stuck trying to test the upload on speedtest.net (2D Chch Server). To LA (AT&T) server 0.49 DL and upload 9.14Mbps.
We don't use our net that much but we've noticed the following things deteriorate:
- Twitch intermittent. However, when it's failing, it can't load any stream at 360p. Picture frozen as soon as page loads, chat continues. Sometimes it will play for 1/2 second and then freeze again, but most of the time it just freezes with no continuation. Desktop (Chrome + Firefox) and also Mobile (Official app + Pocket Plays) - same thing happens.
- Logging into Overwatch can now take up to 10 attempts (however it does log in OK every time to the Battle.net Launcher, just not into OW itself) - keep getting "Connection lost to server". Once I log in, I don't have any ping problems or disconnections.
- "No Network Access" when using YouTube on mobile. I don't normally YT on desktop so no idea about that.
- Housemates watch K-Dramas and that's been buffering non-stop (normally don't have issues with buffering).
Normally I reboot the router when the issues are happening and it will fix it for a while. However, today I still couldn't log in to OW or open Twitch after rebooting, so I tried turning my VPN on (NZ server) and straight away stream loads at 1080p and been running fine for the last hour. Turned it off again just now, back to frozen screen on Twitch with chat updating OK. Also I have tried running Twitch + YT on mobile data (2D for mobile also) at the same time the problems are occurring and they are loading fine, so it does appear to be something with my home connection rather than the services itself.
How can I find out what is actually causing the issue? Ping test? Traceroute? and if so to where?
Edited: Sorry to anyone who may have been reading. It seems I must've ran the speedtests just after it fixed itself so looked like Speedtests were OK when in fact it was not.
