Why is it important to control "Minimum Bitrate" ?
Description
An administrator can improve the performance of clients on the 2.4 GHz and 5 Ghz band by disabling lower bitrates. Adjusting the bitrates can reduce the overhead on the wireless network and also in some cases improve roaming performance.
The minimum bitrate is configured under Devices > AP > Radio
Management and broadcast/multicast Data frames will be sent out at the lowest selected rate.
Keep in Mind that selecting bitrates 12Mbps and above will prevent 802.11b clients from joining.
vAs you increase the minimum bitrate, clients need a higher signal-to-noise (SNR) ratio to join and use the AP.
The highest recommended setting is 24Mbps unless specifically advised by a Sonicwall Tech. Most environments and designs do not provide a great enough signal-to-noise (SNR) ratio for the client to reliably decode all frames sent at a higher rate.
A basic rate is the most backward compatible rate. For example, 802.11b rates are more legacy-compatible than 802.11g rates, because 802.11b was superseded by 802.11g.
As per standards, 6 Mbps, 12 Mbps, and 24 Mbps are the mandatory data rates.
