On any machine which I have experienced this, it has been the cabling in all but one instance. Probably you have a short in the cable somewhere, which when moved just slightly, it works, and when moved a little the other way, it doesn't, or it has enough interference that at GB rates, it is hindered. Replace the cabling (especially if you are successful when connected direct to your switch.)
