I have a Neo-F and it does the same thing.... for a quick ref see
it seems to have improved steadly as 8-current has been developed but
it is by no way fixed yet (even though I suggest switching to
8-current if you can afford the occasional down time from stuff not
working for short periods of time)

*SOMETIMES* just rerunning ifconfig on re(4) will do it (question to
Pyun why does the routing table loose the default route when I do this
even if re0 keep the same ip?)
