1. 运行命令ifconfig查看当前网卡列表，确定名称，如果不在列表内，可能是驱动没装好
   

   % ifconfig
   dc0: flags=8843 mtu 1500
           inet 192.168.1.3 netmask 0xffffff00 broadcast 192.168.1.255
           ether 00:a0:cc:da:da:da
           media: Ethernet autoselect (100baseTX )
           status: active
   dc1: flags=8843 mtu 1500
           inet 10.0.0.1 netmask 0xffffff00 broadcast 10.0.0.255
           ether 00:a0:cc:da:da:db
           media: Ethernet 10baseT/UTP
           status: no carrier
   lp0: flags=8810 mtu 1500
   lo0: flags=8049 mtu 16384
           inet 127.0.0.1 netmask 0xff000000
   tun0: flags=8010 mtu 1500
   

2. vi /etc/rc.conf 添加
   ifconfig_dc0="DHCP"
   dhcp_program="/sbin/dhclient"
   dccp_flags=""

3. reboot后，应该就可以用了
