Agree with other followup--"master" shouldn't be applicable here; figure that
out before you spend more time worrying about hardware. Would you mind posting
a redacted version of /etc/rc.conf (and the contents of /etc/rc.conf.d, if any)?

Any log or kernel messages on either side when this happens?

I wouldn't jump to that conclusion. It's not exactly a new driver and its
author (Bill Paul) was quite experienced. It is possible you have a dodgy board
though.

Most/all 1G NIC's in that price range will be Realtek. You may be able to find
a Marvell/SysKonnect card for a bit more, but for not much more than that you
can get something from Intel. You may get gigabit links from a cheap card but I
wouldn't count on gigabit performance. (Actually any PCI card will fall short
of gigabit performance.) If you actually care then spend the $30 on an Intel
card.
