Howdy all, I am looking for a reliable way to tell if I am currently connected to a network at runtime. I have been looking through the Microsoft.SPOT.Net.NetworkInformation namespace and I am seeing a handler for a NetworkAvailabilityChanged event, but what I am really needing is a method to call that will tell me if I am currently connected to ‘any’ network. I see that there is a method that returns an array of network interfaces: Microsoft.SPOT.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces(); But this method returns one interface even when the Ethernet cable is not connected. Does this ‘default’ NetworkInterface contain any properties that are consistent and unique when there is not a network present so that I may test network availability based on that? Thanks in advance for your help.

Hi

I was just wondering if you ever found a solution to this issue, as I'm sitting in the same predicament.

Any assistance would really be appreciated.

Are you using DHCP? Perhaps you can query the current IP address? Also, they may be network "connect" and "disconnect" events. Worth a look... Chris

In the desktop version of the framework there is NetworkInterface.GetIsNetworkAvailable Method which I'm finding difficult to do without.

It seems odd in MF to have envent that indicate a change in network availability but no property to indicate the current state. Is this an omission in MF or something (presumably hardware specific) that should be provided by a SecretLabs library function.
