Has anyone around here ever attempted to modify or extend the Pronto firmware? Considering that a firmware update consists of just a Linux kernel (2.4.20), and a few JFFS2 firmware images, it may be feasible to replace e.g. wpa_supplicant or mess around with the netifd ([Link: openwrt.org]) binary to improve WiFi handling (or at least extend the delay until the WiFi interface is shut down). The Linux distribution is apparently MontaVista Linux 3.3.1, which is unfortunately commercial. Access to a serial console (there should be a getty running on /dev/ttyMX0) on the remote and the ability to re-flash an unmodified firmware would be almost essential to get anywhere with such a hack.
