¶ Introduction
Legacy 802.11b data rates (1, 2, 5.5, 11 Mbps) exist because Wi-Fi is designed to be backwards compatible with all potential clients. This means that frames which need to be heard by all clients (management and control frames) are transmitted at legacy data rates resulting in higher airtime utilization and lower data throughput. 802.11b is very old Wi-Fi technology, first introduced in 1999. It is unlikely that you will have any 802.11b clients on your network, so we recommend disabling these low data rates.

¶ Web GUI Instructions
The guide was written based on a SmartZone 100 running firmware version 5.1.2.0.302. Your Ruckus GUI may differ slightly.
- Navigate to Wireless LANs > Select the SSID you want to change and click “Configure”.
- Click on “Advanced Options”.
-
Scroll down to see the setting called “BSS min rate”.
-
Select 12 mbps to get rid of the legacy data rates used by 802.11b clients.
¶ CLI Instructions
CLI instructions based on Ruckus Unleashed firmware version 200.10.10.5.246.
Some older ZoneDirector firmware may not have the “BSS min rate” setting available through the web GUI - in this case you can make the same change with CLI. If using Unleashed, you must configure this through the CLI.
- SSH into your WLAN controller. Credentials should be the same as the web GUI.

- Enter command “enable”, then “config”.
ruckus> enable
ruckus# config
You have all rights in this mode.
ruckus(config)#
- Enter the WLAN context configuration with the command:
wlan <SSID NAME>. If your SSID has spaces in the name, use quotation marks.
ruckus(config)# wlan "Get off my LAN"
The WLAN service 'Get off my LAN' has been loaded. To save the WLAN service, type 'end' or 'exit'.
ruckus(config-wlan)#
A typo in this command will create an SSID with the exact string you input. If you made a typo be sure to delete the bogus SSID.
- Enter command:
bss-minrate <NUMBER>. To set the minimum data rate to 12mbps, the command isbss-minrate 12.
ruckus(config-wlan)# bss-minrate 12
The mgmt-tx-rate will be set to the same value as bss-minrate.
The command was executed successfully. To save the changes, type 'end' or 'exit'.
- Validate the new min data rate applied by using command:
show. You will see the mgmt rate is set to the minimum rate you configured.
ruckus(config-wlan)# show
