Title:
  168c:002c [Eee PC 1005P] Frequent disconnects only at Honk Kong
  airport

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I'm currently at the Hong Kong Airport.  Free wifi is offered and I
  believe there are multiple AP transparently networked together.  I am
  using a 1001P netbook and the wifi is unstable, reconnecting about
  every 30 seconds.  Judging from the syslog it looks like this is due
  to failed roaming ("Roamed to ... none").  Obviously, I will not be
  able to repeat this problem after today.
