¶ 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.
