OK I have loaded bwn_v4_ucode before if_bwn and it works, my bad, I should have read the man page more carefully. > > 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 no messages in the log (appart bwn0: need multicast update callback). In fact it's not a hang, it happens only with the AP that permits me to have a web access. I have another AP (sitting next to me) and I don't have the same behavior : I can have and renew my dhcp lease multiple times and configure the AP with its web interface. With the "buggy" AP I can have a dhcp lease only once and nothing more. If I destroy and recreate the wlan interface the same thing happens. I have no such a problem with if_bwi and this AP. > > 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? > Setting hw.bwn.usedma=0 in loader.conf make no differences by the way, I need to switch from if_bwn to if_bwi to make some test and post the results here, but I have this error message : firmware_register: cannot register image bwi_v3_b0g0initvals5, firmware table full! is this normal ?
