That's poor management by your network hardware. (could be your modem, router, ISP, etc) I ran two zoom meetings on my 1.5MBit DSL connection before I got Starlink and it worked fine. Or I could run Netflix and a Zoom meeting. Never did try to push it much past that. But on 100mbps, there's something else wrong there that you can only get one more connection than my shitty DSL line lol.
