Advertisements Maybe my search fu is failing me but thought I'd go ahead and ask. I'm trying to connect a tivo premiere to my network via ethernet cable. It's actually been working for a while now but I had to plug the cable into a usb adapter because it won't connect if I just plug the cable into the ethernet port. I need the adapter for something else and would like to get it working without it. Is this a known issue? Any idea what the difference could be?
