Horrible bufferbloat on a Fritzbox 7590 - good router for gaming? - eviltoast

Hey guys,

in the process of troubleshooting my strange problems in online multiplayer competetive gaming I stumbled upon buffer bloating and I did the test for myself and found out that my internet connection suffers from a high buffer bloat on the upload side:

I did some research and a lot of people report the same problems with the Fritzbox 7590 and thus I’m thinking about changing router as the fritzbox 7590 doesn’t seem to fit the needs of competetive online gaming.

Is it reasonable to assume that this problem is connected to the router and that change to a router with a better SQM/prioritising would get rid of buffer bloating?

If so what router at a reasonable price would be a good choice?

Thanks a lot in advance!

    Bufferbloat tests can be misleading, you only get bufferbloat when your saturating your connection. Gaming does not use a lot of bandwidth (maybe 2-3K), it does however, require low latency. Is your gamer WiFi or wire connected to the internet? If using WiFi try a cable.

      Yes - bufferbloat occurs when saturating the link. And, yes - gaming rarely does.

      BUT… if anyone else in the house (or any other device in the house) uses the connection, even for web browsing, it briefly saturates the link all the time.

      That’s why bufferbloat events are so sporadic. They aren’t related to what you’re doing - it’s the other stuff using your internet…

        nice to see you rich!

        u/rockker60 :

        I try also these days to express that the bufferbloat induced jitter is caused by *any* flow lasting long enough (a few hundred ms tops) to hit the buffers. The tcp algorithm at fault is called “slow start”, and if I could merely convey intuition from getting more people to lose 30 seconds laughing with the jugglers emulating that here here, perhaps we could get somewhere faster.
