Okay, so in the meantime, I found a reason why AirLive card did not
work properly. Cable supplied with DLink card had borderline connector
:-(.
AirLive (rt2800) card is actually stable, even on USB 1.1 -- it
survived overnight testing.
I still got around 5% packet loss -- it seems every minute or so
connection fails for few seconds -- but TCP connection survived
overnight, doing ~1MB/sec all the time.
So AirLive card works here.
