    Default Zoom bandwidth throttling

    I'm an Untangle subscriber and could open a support ticket, but thought it may be better to get the information on the forum for others.

    My bandwidth is 100Mbps down/5 Mbps up.

    With the switch to remote work and online schooling, Zoom has become a major problem.

    Whenever I do Zoom calls for work (with no video), we can use nothing else in the house. The problem gets worse when my kids have Zoom calls for school with full video. For the work Zoom calls I've tried on and off VPN, thinking it was a VPN issue, but even off VPN the internet becomes unavailable to everyone in the house. Normally I'd tell the kids, "tough, go play outside", except they are actually doing school!

    The weird thing is when the other devices can't even connect to the internet, I'll check Untangle and I'm only using about 1.1Mbps down and 0.4Mbps up. Speedtest still shows my full bandwidth. So why can no one connect? And if they can connect, why is the internet so slow? What am I missing?

    What are some suggestions on how I can throttle Zoom and still get a good experience out of the calls and still be able to work?

    Are you using QOS? It might be buffer bloat. Maybe someday they will take up this great offer.

    This is sad, but I've never used QoS in the past, with the good bandwidth I haven't had to. I'm not even sure where to start. Will QoS help if it is bufferbloat?

    Bufferbloat.net mentions "Untangle NG Firewall has fq_codel settings." Is this just inherent or something I have to configure? I found this:

    Look at https:yourip/admin/index.do#config/network/advanced/qos.
    Not sure it will help but might.

    So I followed that Untangle post I put in post #4. My bufferbloat score went form a B- to an A, but haven't tested during Zoom yet.
