Plugable USB 3.0 3-Port Bus Powered Hub with Gigabit Ethernet losing internet connection

Hi,
I recently purchased the 3 port usb hub with ethernet adapter, Plugable USB 3.0 3-Port Bus Powered Hub with Gigabit Ethernet. All the usb ports work fine but the ethernet loses conectivity after a minuter or so. It says it is connected but no internet. I’m pretty sure it is this plugable adapter because I used another ethernet usb adapter and plugged it into a usb port on the unit, and it worked.

Does anyone have a solution? Is it just defective?
