this is not working for me. I'm using 4.2 RC5 and the event about network up/down is not propageted. Anybody using RC5 too?
Sorry, I can't help you. I gave up after a rude personal email from Chris. I literally threw all the netduinos my company used in the garbage bin and replaced them with devices from GHI, and use those plus custom hardware exclusively now. That's the only recommendation I can make, but someone else may have found fixes in the 4.2 RCs.
