This is expected behavior and is typically caused by one of the following:

• Overload: If multiple high-power devices are connected, unplugging the PD wall charger may briefly interrupt power to the hub.

• No Fast Role Swap (FRS) Support: FRS allows USB-C devices to switch power roles without interrupting the data connection. If your laptop's USB-C port does not support FRS, unplugging the charger may temporarily interrupt the connection.
