    Hello,

    I have several computers at home that have a USG Flex. 100 run. If a PC now makes a download, it takes up the entire bandwidth. How can you set it up so that you can prioritize PCs. Is this under BMW?

    greeting
    Marcus

      Depending on your setup there are many ways to go about this however there are some things when BWM can't help like bandwidth from your ISP is shared and say you limit to 90Mb but the max you can download is 50Mb BWM does not see this and so the PC doing a download get all bandwidth. If you have more then one LAN/VLAN you be egressing out many interfaces so if you have max 90Mb you have to think how much bandwidth to give each interface because ingress rate limit is not that good (last time I checked) a way around this is to have other USG as bridge to do all BWM as a total.

      I simple setup is to enable BWM without rules go to you WAN interface and set the egress of your upload speed -0.9Mb of what speed test shows you say its 10Mb you limit at 9.1Mb so 9280Kb go to your LAN interface and -10Mb of your download speed say 100Mb limit to 90Mb or 92160Kb

      https://www.aqua-calc.com/rate/bandwidth-calculator

      You can add rule in BWM to limit more and by IP or WILDCARD FQDN like *googlevideo.com if clients use DNS and not DNS over HTTPS to Guaranteed Bandwidth in my case inbound 71680Kb and outbound 3200Kb at priority 7 which is recommanded if you use Maximize Bandwidth Usage and didn't set a maximum limit.

      And I recommanded you enable this option by webconsole which Zyxel should really add on the UI.

      configure terminal

      bwm control-tcp-ack

      write

      Hello Kevin,

I have now set this. Our line is 180MBit. My son now uses 50MBit. Now 125MBit remain. Nevertheless, other clients are a bit slower.
It takes a little longer for a website to open.

      Hi @Niro96, 
      Please select BWM-Type to "Per Source IP". 
      Otherwise 50M will be divided qually by all users.

      If your looking to rate limit a LAN IP you set Guaranteed Bandwidth to 64Kb both inbound and outbound and set maximum for inbound to 50000Kb and outbound to Maximize Bandwidth Usage with priority 7 for both.
