2 hours ago I installed SX virtual link, and have been using it instead of shareport utility from D-link,
and doing the extensive tests with one printer and one external HD from 2 XP machines,
so far so good. No more hang at 'available' status. And more than 2GB data transfer from HD
thru wireless without any problem. Everything works perfectly. I'm very happy with it.
I'll keep testing because someone here experienced it stopped working after a couple of days.
By the way, the firmware is 1.31.
(I haven't upgraded to 1.32 because many people reported secureport problem in 1.32).
