A year ago spend relatively long time troubleshooting my home network problem and the root cause was the same: 1. USB-C hub with an Ethernet port send pause frames when it is powered but a laptop is disconnected 2. TP-Link Wi-Fi router broadcasts pause frames to all ports which causes all connected devices to stop sending traffic. TP-Link (or more specifically Atheros AR8327 used inside it) here is likely breaks a IEEE standard (may be even the most basic one - 801.2d), but when no-one send pause frames this goes unnoticed. As workaround now don't connect power to the hub and instead connect charger to a laptop directly (if a hub is powered you can connect only one cable to s laptop to get both - power and external USB+Ethernet).
