Setting APs to 802.11g only

Is there a way to set up LWAPP APs so that only 802.11g devices will be supported?

My understanding is that any 802.11b device that attaches to an AP will cause the AP to then operate in 802.11b compatibility mode, and thereby decrease the max bandwidth to 11 mb, i/of 54...

I thought the APs could be set up so that they would only support 802.11g, and would not fall back to 802.11b data rates.

So - is my 802.11b fallback belief correct? and, if so:

can the APs be set to 802.11g mode only?


Re: Setting APs to 802.11g only

Of course you can. You can set that in a per WLAN basis, choosing in the properties of the wlan the radio policy "802.11g only"

You can also do it in a global mode, going to wireless menu, and unchecking the 802.11b in the 802.11g radio menu.

Thanks for your reply.

We cannot use the per WLAN setting as we can only do this on some APs in certain locations; all APs broadcast the same campus SSIDs.

I did look at the Wireless menu on the controllers, and all I could find that seemed relevant was the 'Network' setting under 802.11b/g/n. The options there are:

'802.11b/g Network Status'

'802.11g Support'

If I uncheck either setting then the Data Rates change such that all rates above 11 mbps are no longer listed.

SO clearly that is not what we are looking for.

I could find no setting that would allow me to uncheck any option for just 802.11b...

So I am still stuck.


Re: Setting APs to 802.11g only

Ummm yes, you are right. Ok, then I think your only option is to set 802.11g data rates as mandatory.

If you set for example 18Mbps as mandatory, an 802.11b card will not work.

Hope it helps..

Hmm, that is an interesting idea- we will have to play around with that option.

Thanks again for lending your brain power!
