To explicitly answer your new requests to the best of my ability:
+ Is this a regression?
+ Does this occur with other wireless access points?
I don't know. I never into it before AFAIR. But the situation is obviously special and occurs only where a roaming setup of several AP with the same ESSID is deployed. Furthermore, it's safe to assume that an airport such as HKG is wifi-busy. The problem might not occur in other, less congested environments. I have never experienced the problem since and connected fine to a few wifi networks (but in less congested areas and without a roaming setup as far as I am aware of).
+ Does this problem occur in mainline?
untested at the moment, still pending as tagged
+ Does the access point in Hong Kong have some firmware bug or access policy that does not permit Ubuntu/Linux clients?
I think we should assume no. I was able to surf for several minutes at a time.
+ What is the manufacturer and model of the access point?
that's a silly question. I don't know. I'm not going to contact the airport and ask them. There *IS* a limit to what I will do to help bug triage.
