FWIW, I've never had to ping anything before getting the overo to associate to an AP. 

One thing to note if you use Steve's gnome image is that it is using NetworkManager to control networking (just like a typical Ubuntu desktop would), and sometimes NetworkManager doesn't play nice with iwconfig and ifconfig run from a command line. So if you want to use iwconfig/ifconfig in the gnome image and things aren't seeming to work try killing NetworkManager and see if things work better.

Thanks Henry. Fortunately we're not using WPA (yet) but I understand that may be a separate can of worms.

Do you ping in a shell script or do you do it in the /etc/networking/interfaces file? Thanks for the heads up there, I didn't know about that tip.

In short: Does anyone have a known working overo image that does not have wifi time out? I really feel dirty running a "ping -i 60 google.com" in the background just to keep wifi working.

Specifically this image has the following property:
  1. Does not turn off wifi after 2-3 minutes of inactivity.
We rolled our own image and do not have that problem. However, I have noticed that it won't even try to associate with an AP unless you try to ping an IP before associated. I know it's backwards, but that's what we've seen. Also, we've noticed that wpa_supplicant sometimes refuses to connect to a preferred access point in its configuration if the last access point it was connected to is in range. The only way to overcome that was to put an invalid passphrase for the unwanted network.
