Bah. I wonder if > there's something wrong with my driver. There is plenty wrong with the driver, also with the product. Unfortunately= ,=20 Intel does not support the FreeBSD team with developers for the wireless ca= rds=20 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=20 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, eff= ort=20 spawned from this list, but as of yet I haven't seen anything hit the sourc= e=20 tree. =2D-=20 Mel
