Which driver and driver version are you using? Is this an open network
or are you using WPA or IEEE 802.1X?

I haven't seen this in my tests with N95, but I don't remember whether I
have tested this with Host AP driver (it was more likely with madwifi).

It would be interesting to see the full contents of that frame

I would not expect this to be the main reason, but the problem may be
related to N95 power saving. I've seen it having major interop issues
with many APs.. You could run a quick test by disabling power saving in
the phone (Settings, Connection, Wireless LAN, Options|Advanced
settings, disable automatic configuration, disable power saving). If
this resolves the issue, I will try to figure out whether there would be
a way of working around this somehow.
