Did you try to UP the interface withload loading bwn_v4_ucode.ko? If
yes currently bwn(4) doesn't automatically load firmware module so you
need to do it by hand.
# kldload bwn_v4_ucode
The patch for this is ready to commit and it'll be happened soon.

I have a exact same device like you have but I didn't encounter this
Are there any messages from bwn(4) when you the interface becomes hang?
One more question, after the interface hang, does the system be hang
One thing you can do is that trying the device with PIO mode not DMA
mode using the following tunable variable:
Its default value is 1 to enable DMA operation so if you set it 0, PIO
mode would be used and could see the message like below:
Could you please test with it?
