Hi,

I think you misunderstood. The batman (internet) client will not "check" if 
the internet connection is available or not. It waits until the user wants to 
connect to the internet and than observes if the requests to the internet are 
answered or not. Of course, batman will wait until a timeout is reached and 
wont kill the connection instantly.

In addition this is a good thing to do. But it should be implemented by the 
firmware maintainer and not by us.

You are not the first who has the idea to do so. Unfortunately this approach 
does not work everywhere. You should get in contact with Sven-Ola (the 
maintainer of the dyngw plugin) and ask him what his latest solution consists 
of.
