I had a particularly challenging evening because the hastily assembled wireless network in the ACTlab refused to hand out an IP address to the radio. After wrongly suspecting that the 802.11n network was causing problems (my home network is b/g), I discovered that if I set a static IP and default gateway, I could get a stable connection to the router. That process of discovery took something like an hour of tweaking settings, trying to remember iwlist arguments, how to set up routes, etc.
In the end I got it all working and gave a very successful demo of the radio. Whew!
