I've only tried our single office AP. I'll see if I can find a new network and test it out.

Thanks for the ideas Steve & Chris

I've also not had any issues running wifi for days at a time. I've used the omap3-console-image built from the overo repository, images from Steve's repository (both by using his script to download and  create a bootable sd card and by cloning his repo and builing the image myself), etc. 

I'm with Steve on this most likely being an infrastructure problem. Have you tried connecting with a different AP? Different settings? There is one AP here at my office that I've never been able to get my overo to connect to, although it can see it just fine using iwlist. Not sure what the deal is, but it just doesn't work for me. Attempting to connect to just about any other AP works though.

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??
