The basic problem is your card is losing sync w/ the ap. I don't know

nothing we can do in the driver if you want to be able to roam.

Update: this was just fixed in iwi(4) in -CURRENT (by increasing the
beacon miss threshold for the iwi(4) driver from 7 to 10). Should 10
not be enough, it is now also possible to set the beacon miss
threshold using ifconfig.

Thanks to Sam for helping and for applying my patches to
-CURRENT. This functionality should be MFC'd in two weeks.

Thanks for your help but understand this is not necessarily a solution;
just the addition of a knob. The linux driver already used 7
consecutive beacon misses to trigger roaming so I'm not sure why 10 is
an improvement but given that adding 300ms (typical) lag makes you happy
I wasn't going to argue :)
