Below is my summary (correct me if I'm wrong):

(1) A RSN is a network supporting RSNAs only. A BSS can be considered as a RSN if all of devices use CCMP/AES or TKIP/RC4 only.

(2) A pre-RSN is a network supporting pre-RSNAs only. A BSS can be considered as a pre-RSN if all of devices use static/dynamic WEP encryption and legacy authentication methods only.

(3) A TSN is a network supporting both RSNAs and pre-RSNAs. A BSS can be considered as a TSN if some devices use CCMP/AES or TKIP/RC4, while others use static/dynamic WEP encryption.

(4) WPA2-certified devices support the use of CCMP/AES, TKIP/RC4, and WEP/RC4. WPA-certified devices support the use of TKIP/RC4 and WEP/RC4. Neither WPA2-certified nor WPA-certified devices support the use of WEP/RC4 only.

Hope it does not sound confused... (again, correct me if I'm wrong.)

Based on the summary above, a 'WPA network' should belong to TSN since both RSN devices (using TKIP/RC4) and pre-RSN devices (using WEP/RC4) could coexist in a 'WPA network'.

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.
