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 installed bwn-firmware-kmod from ports but the only files I have in > /boot/modules are bwn_v4_lp_ucode.ko and bwn_v4_ucode.ko.

I have a exact same device like you have but I didn't encounter this issue. 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 also? One thing you can do is that trying the device with PIO mode not DMA mode using the following tunable variable: hw.bwn.usedma 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: bwn0: PIO Could you please test with it? regards, Weongyo JeongReceived on Mon Mar 01 2010 - 19:13:13 UTC
