[Contiki-developers] Problems running Contiki 2.4 Demo forAtmel Raven and SICSlowpan under Windows Vista

[Rolf D. <Rol...@de...>]

Yes, I was watching the traffic with Wireshark, but Contiki, the Raven and Wireshark is all new for me. 
After removing the TCP/IP v4, the Raven USB interface no longer shows this long delay. The network interface is "available" after approx 3 to 4 seconds now, that's really an improvement.  
I will follow up your other hints and look into your pcaps files tomorrow. 

Thanks again
Rolf

Here's another possiblity for that delay and a way to disable it using the 
registry. Note the AAAA lookups in my pcap. Vista tries very hard to find 
microsoft servers, bless its little heart.
