I've been testing AIR in the last day and I saw a very similar thing on both MacBook AIR and a Windows 7 PC both running AIR 2.1.2. The Devialet is hardwired. With the MacBook I was streaming from it over wifi using Audivarna or VLC. It's a wireless N connection and usually on 5GHz and I'm about 3 metres from the access point which is a triple-antenna jobbie. . In the case of the PC is was testing jRiver with jRemote so any dependency on wifi was minimal. The AIR driver just seems to crap out (and be greyed out). It seems to happen more often when I'm performing some action such as changing volume, but I could be mistaken. I'll look in the Windows logs to see if anything obvious shows up. Like you, it's hit or miss reenabling AIR. Sometimes it starts immediately, other times it takes many attempts.
