Since Probe Request frames carry an immediate receiver address (Address1) of FF:FF:FF:FF:FF:FF, they are considered "addressed to everyone in the BSS." The duration/ID field is ignored by stations addressed by Address1, and therefore it would have no effect. Seeing a station do this tells me that the driver is hosed (not uncommon). The standard says the value of duration/ID in a Probe Request should be 0.

Sorry Gene. I couldn't resist. ;-D

What would be wicked cool would be to see an AP virus that rewrites the firmware to cause each Probe Response (unicast) have a large duration value. An AP would then DoS its own BSS everytime a station probed. :-D

Success Stories

I literally just came out of the testing centre having taken the CWDP exam. The certification process opened my mind to different techniques and solutions. This knowledge can only broaden your perspective. Great job, CWNP, you have a great thing going on here.
-Darren

Working through the CWNP coursework and certifications helped not only to deepen my technical knowledge and understanding, but also it boosted my confidence. The hard work it took to earn my CWNE has been rewarding in so many ways.

I want to commend you and all at CWNP for having a great organization. You really 'raise the bar' on knowing Wi-Fi well. I have learned a ton of information that is helping my job experience and personal career goals, because of my CWAP/CWDP/CWSP studies. Kudos to all at CWNP.
