There is plenty wrong with the driver, also with the product. Unfortunately,
Intel does not support the FreeBSD team with developers for the wireless cards
as they do with the wired cards and the iwi driver is particularly plagued.
At present the best working Intel wireless on FreeBSD is the wpi, but it is on
the virge of the same fate as Benjamin Close is lacking time to support it.
There's a group of people working on improving iwn for the 5000 series, effort
spawned from this list, but as of yet I haven't seen anything hit the source
