I've got my trusty old A1000 too (its, geez, like 6 years old now), and
in all the time I've used it, I've never noticed any weird duplexing
behavior. And I do all sorts of crazy stuff, like heavy duty gaming, and
IPSEC and other sorts of vpn on that connection. I always get 1200+ down
and 200+ up though, too.
