I played around with WiFi (802.11) over the weekend. And found that promisc mode is not working on the 770, this means no fun with tcpdump or dsniff (which I spend hours on building). Also the whole monitor mode thing doesn't seem to work right now. When asking on the developer list about this issue, I got told that they are currently working on these things (due to popular demand!), which is nice to hear.
Also changing the MAC address of the device seems to work, its not really a feature that is needed by many people but I happen to need it.
