I have followed iwn(4) and installed what I thought was the right firmware.
/boot/loader.conf
Code:
if_iwn_load = "YES"
iwn60002bfw_load="YES"
/usr/src/sys/amd64/conf/GENERIC
Code:
device          wlan
device          firmware
device          iwn6000g2bfw
And just in case it may help, here is pciconf -lbev:
Code:
iwn0@pci0:2:0:0:        class=0x028000 card=0x13158086 chip=0x08868086 rev=0x67 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Centrino Wireless-N + WiMAX 6150'
    class      = network
    bar   [10] = type Memory, range 64, base 0xd0500000, size 8192, enabled

    bar   [20] = type Prefetchable Memory, range 64, base 0xd0400000, size 16384, enabled
  PCI-e errors = Correctable Error Detected
     Corrected = Receiver Error

Please old wise ones, direct me through my moment of ignorance. Thanks for any and all advice.
 
Driver is OK
The connection look good (all ping was reply), but only the time of response is very variable. The ping tool only send 64 bytes of data.

I imagine surfing the internet is very slow for you.

There is another device without FreeBSD with the same problem ?
Interference by the microwave?
How close are you to the router?

I am only getting a wireless connection if I sit right next to the router. I followed a firmware tutorial and got it working flawlessly, but a couple hours later my laptop crashed for unrelated reasons and I haven't been able to reproduce the fix since.

Time ago I had the same problem with the Intel Wireless Pro 3945abg driver. Without no reason FreeBSD enter in Kernel Panic after a few hours.

The driver was newly and was still a beta test. Never work fine for my laptop ( In that moment a VAIO VGN-N350 )

Try to find some clue on logs file see if any DIAGNOSTICS messages was sent.
