USB3 Ethernet randomly disappears as does the external harddrive attached to it

I have a USB3 Hub with Ethernet. It’s attached to a Dell Inspiron running 8.1. The hub “disappears” occasionally, requiring me to unplug and replug it in. Also, the external harddrive that it is attached will also disappear randomly too, complicating the auto-backup. I have tried the Plugable in all three of my USB ports (3, 3 w power, and 2). Same problems.

Hi Stephan,

Thanks for posting. I’m sorry the adapter isn’t working properly. I’d be happy to help.

Based on your description it sounds like you may have a faulty unit. I see you have also reached out to us directly via The best way to proceed is to arrange for a pre-tested replacement adapter to be sent out to you. I will work with you directly via our support ticket system to get the process started.

Thank you,
