I use
MyHouse daily, and for the past few weeks, there does seem to be a few times through the day that I cannot connect either. I have 2 separate set-ups on 2 separate computers at home so I'm certain this problem is at
X10's end. Plus when I look at the
MyHouse log at home, I can see the repeated
"waiting xx seconds" messages.
With the distance you have, I suggest a reliable backup method like
RealVNC (
an awesome free program) or
XP's Remote Desktop.
