Steve,
  Great idea. It's an old router, and on the new image I get a message that indicates it's looking for a country code before dropping...
"Calling CRDA to update world regulatory domain"

Now you've got me curious. I wonder what about our hardware, possibly, could cause this?

I'll try the gnome image, thanks a lot. we don't need desktop but it's a good start. Great script by the way!

Blaine

I've never seen wifi timeout on my GNOME image:

I have wifi up for days at a time.  I'm wondering if it might be
something in your wifi infrastructure??
