In monitor mode, all received frames will be forwarded to the network and not just connected to the customer at the time. This is in contrast to the promiscuityMode. One advantage is that not a single image to be sent from the network card and so that the frames do not appear in any log file. In addition, network authentication is not required. If the packets are encrypted with WEP frame, for example, can be captured and decoded later.

Some network card drivers switch to monitoring mode, the CRC checking of the verification regime under false images that can be sent the results. The integrity of theThe data are not really in monitor mode to save.

Moreover, not all wireless card drivers can pass through the monitoring network because it is not saving at all. Some of the damaged packets can be sent as it has not occurred in monitor mode, the wireless card, if the CRC is correct.
