About This Document

With the development of Wi-Fi technologies, WLANs have become one of the main methods for enterprise network access, and users have higher requirements on WLAN experience.

For WLAN users, good Wi-Fi experience is perceived through full signal strength, smooth Internet access without frame freezing, and unaware roaming. To meet users' requirements for WLAN experience, WLAN maintenance engineers need to continuously maintain and optimize the WLAN to provide better user experience.

This document provides multiple network optimization methods and related cases to guide WLAN maintenance engineers through WLAN optimization. If you are unfamiliar with WLAN optimization methods, you can optimize the WLAN by referring to Basic WLAN Optimization Measures. If you are familiar with WLAN optimization methods, it is recommended that you optimize the WLAN by referring to subsequent optimization methods, such as radio calibration, wired network optimization, and STA optimization.
