Google之后 ,发现有如下内容:
The patched Orinoco drivers don't support the wireless extensions method of enabling monitor mode. Try "iwpriv eth0 monitor 2 1" where "2" is monitor mode and "1" is the channel number. Running "iwpriv eth0 monitor 0 1" should revert to managed mode, but it's often better just to run "cardctl eject ; cardctl insert" instead.
