The driver tells you it can't find the modules. Are the modules installed? If yes, load them with . The modules are in /boot/modules, and the driver works without hw.bwn.usedma=0.找不到模块的原因

 ports中net/去安装（是用其它电脑和U盘复制过来的）

   bwn_v4_ucode.ko

kldload  bwn_v4_lp_ucode.ko

或者：

if_bwn_load="YES"

bwn_v4_ucode_load="YES"

bwn_v4_lp_ucode_load="YES"
