First I like to know the meaning of all the fields of the debug level prints and how they are determined. It would be great If you can give a more detailed information when to use the extended options and what they do with batmand. For instance, why should I change the window size (seen in Graz experiment). My setup is the following. I have a laptop (linux debian) on a table. under the table I have a WRT54GS about 50cm below. A second router WRT54GL is places on the top of a cupboard which is about 1m higher than the laptop and about 3 m away. The laptop is offering a gatway. Table (wrt B 10.12.10.1) (laptop 10.12.0.1) ########### (wrt A 10.12.10.17) # cupbord ### laptop ------------ wrt A | | wrt B---------------+ My problem is that the connection from the laptop to B is bad (ssh,http connection). batman setups the routes so each device has a direct connection to the others. OLSR has detected this and does not use the direct connection between laptop and wrt B. It creates an routing entry to route over wrt A in laptop and wrt B. This results in a fast and better connection. laptop wrt A | | wrt B---------------+ My problem also causes that the wrt B looses the gatway (laptop) and removes the default routing entry. I have added some traces of the three devices. All devices stay directly connected to each other. After network start wrt B still shows the gatway of the laptop (over the bad connection). Later the gateway will vanish and come back only for a short time before vanishing again.
