I've also suffered from the similar problem. After some huge traffic, the
wireless network freezes and does not deliver any packets, though the
disconnection isn't indicated explicitly. But in my case, it doesn't
require rebooting to reconnect. Just choosing the access point again on the
list fixes the problem.

I'm not sure when exactly did the problem start to occur, but about half a
year passed since I noticed the problem. I've just endured because it
didn't bother me that much. It is shameful that I haven't reported the
problem, though.
