Working with an RCM6600W. I'm periodically polling ifpending() with the wifi/ethernet interfaces, but even when pulling the ethernet cable from the port, or powering down the connected access point, the status of the interfaces doesn't change. (The wireless at least changes status a few times when it comes back online, but the ethernet doesn't even do that much)
Is there something else that I could be using to determine the status of the interfaces, or do I need to implement some kind of higher level "keep-alive" protocol?
