I'm assuming this is done through CLI, but where would I go to find the commands for this?

You need to configure this over CLI. <BR /><BR /> Here's the CLI guide for FW 9.6 <A href="https://support.ruckuswireless.com/documents/276-zonedirector-9-6-cli-reference-guide/download" rel="nofollow">https://support.ruckuswireless.com/do...</A> <BR /><BR /> There on page 247 you will find the answer and, if I'm not mistaken it goes like this <BR /><BR /> &gt; enable <BR /> # config <BR /> # wlan your_wlan_name <BR /> # ofdm-only <BR /> # exit <BR /><BR /> To check if 11b has been disabled <BR /><BR /> # wlan your_wlan_name <BR /> # show <BR /><BR /> look for "OFDM-Only State" to be ENABELED. <BR /><BR /> You enable it per SSID (WLAN). So you have to repeat for every SSID you create.
