    Posted Aug 24, 2018 01:09 AM

    Hi Experts,

     

    We have a 100 IAP (315) cluster and needs to disable 802.11b radio as it is legacy one.

     

    Can any one suggest how to disable it?

    I have checked in IAP GUI but did not find that option.

     

    Thanks and regards,

    Ashok

    You would make the minimum transmit rate 12 for 2.4ghz in the SSID configuration.  https://www.arubanetworks.com/techdocs/Instant_423_WebHelp/InstantWebHelp.htm#UG_files/WLAN_SSID_conf/ConfiguringWLANPro.htm?Highlight=ssid

    802.11b has transmit rates of 1,2, 5.5 and 11 Mbps. By setting the minimal transmit rates at a value of 12 Mbps, you are basically denying b rates to be advertised and utilized.

    802.11g uses OFDM however which has transmit rates of 6, 9, 12, 18, 24, 36, 48 and 54 Mbps.

    So by setting the minimal transmit power at 12 Mbps, you are denying the lowest 802.11g rates which might have an adverse effect in some situations and can cause unwanted retransmits. In that case, adjusting the minimal transmit rate to 6 Mbps also does the trick as 6 Mbps is not a 802.11b rate.
