for me this is more of a general prioritisation problem that should actually be solved by the router without prioritising individual devices.

My IB delivers a B- with g.fast 450/120, and an A+ even under full load if I configure my downstream router accordingly.

Try doing the test.

    I assume that this is exactly why your “internet experience” is not so great. Under load, the IB still gets bogged down with the even distribution of resources.

    By the way, here is a thread in which the topic of performance and bufferbloat has already been discussed.

    https://community.swisscom.ch/d/766796-pfsense-schlechte-performance-mit-modem

    It is now almost 2 years old, the topic was already present at that time, and apparently a solution was already being worked on. Perhaps this error (O-Ton on the Bufferbloat test page: Bufferbloat is a software issue with networking equipment that causes spikes in your Internet connection’s latency when a device on the network uploads or downloads files.) has already been fixed in the new IB5pro? It is also interesting to note that, contrary to other statements, this technology is also effective at higher bandwidths.
    I still get practically identical measurement results today, unfortunately not much has changed in the meantime on the software side with the IBs.

      Test was just interesting but I don’t see any connection with my problem. During the test, the load and test are generated and measured from the same IP (pc, laptop). My problem is only when other devices fill the line. I could also see that QOS helps via cable. But I don’t have the option of prioritising my laptop via WLAN as I can’t select it because it’s not visible on the Prio config page.

        I now suspect that something on the laptop is preventing the IB3 from recognising it for QOS. As written, otherwise I see every device that I connect to the WLAN. No matter if 2.4 or 5Ghz, no matter if WPA2 or 3, etc, they all show up on the QOS page and I could select them all. Does anyone know what the exact requirements of the IB3 are for QOS?

        Otherwise I will probably have to reset the IB3 and see if that helps.

          Give it a try, but that won’t really solve your problem.

          The router does not handle the Internet requests from the various devices correctly under load. The requests that generate a high load push the others away. This is a problem with the software on the router. Manually down-regulating individual devices in the IB menu using the QoS menu is only a workaround that often, but not always, works. Swisscom is aware of this problem, but has so far given too little priority to solving it.
