I have a new, unmodified, never-reflashed connex 200 with a NetMMC (with and without a Robostix, identical results), and I, too, am seeing the Ethernet connection briefly come up at boot time and then disappear after it DHCPs (DHCP is verified by router logs, as I don't yet have serial console access -- I need a TTL-RS232 xvrtr for the Robostix).
I've tried connecting through a 3Com 10BaseT hub to avoid speed negotiation, but the hub won't see the Gumstix' link beat (no link light; something I've seen with other Linux systems on these hubs, probably a hub issue). I'll try again with a different hub.
Searching the archives, I'm not at all certain whether there's a known fix for this issue; can anyone point me to a definitive cause and solution, or just a solution?
Thanks, Steve H
Each of us has strengths and talents that others don't. Whether innate or learned, these are gifts -- and a gift not shared is a sad and lonely thing. Using our gifts for the benefit of all is an ethical obligation for every intelligent being. (The magic only works if you pass it on!)

For the benefit of those who follow after:
I logged into the Connex by itself using a Tweener, and edited
/etc/network/interfaces, commenting out everything related to wlan or
Bluetooth, neither of which I'm using. After reboot, the reassembled
Connex+NetMMC+Robostix comes up and is accessible via SSH through the
Apparently, something in the attempted startup of the absent WiFi adapter
nukes the Ethernet driver setup.
Moral of the story: The tweener: don't leave home without it.
