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.  Read the link below.
