John, for Gigbit to work properly I think **everything** must be Gigibit, i.e. all network cards, wifi, routers, switches, etc. I think Gigibit uses jumbo-frames. Otherwise you can have a mixed-mode condition. You do not mention what kind of router/switch you have, consumer/business/enterprize. Oh forget enterprize--too expensive. :-) Some routers/switches may support mixed-mode.
