Welcome to the wonderful world of wireless support in FreeBSD. Rather
that wasting your time hoping in vain that FreeBSD will actually
provide suitable drivers for high grade wireless devices, might I
suggest the following.

1) Install a good quality NIC card -- obviously one supported by

2) Connect that card to a suitable wireless N router. I use the Linksys
   E4200 with excellent results.

You will now be able to use all of your wireless devices, such as
printer or connect to other wireless networked PCs.

I might add, whenever possible, keep FreeBSD and USB devices as far
away from each other as possible. DO NOT attempt to connect a router
via USB to FreeBSD. Connect it via cable. Otherwise, you are just look
for trouble and pain.
