Greetings,

I'm looking for a way to disable 802.11b in a 802.11ag environment. The wireless hardware is all Cisco (variety of controllers and 1242s, same problem on each) and my method so far has been to disable all CCK data rates (1,2,5.5,11) and require or support all OFDM rates (6,9,12,18,24,36,48,54) under the 802.11b/g Global Parameters.

After doing this, I've looked at my controller statistics and independently checked using AirMagnet WiFi Analyzer: still 802.11b traffic going across my network. Is my goal possible? Is there any way - even with another vendor - to truly disable 802.11b in a 2.4GHz environment?

Thanks in advance!

If you can control required rates on that gear make 12 a required rate. Since B clients can not do 12 they will not be able to connect.

Keep in mind this will not stop 802.11b protect mode if the B traffic is near by.

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.

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.
