When a user's Wi-Fi network experience is poor, frustration frequently results, and the wireless network is quickly blamed. Frequently, another party is to blame. In this article, I'll discuss how poor network segmentation, DHCP, DNS, RADIUS, and other frequently disregarded issues can affect a device's experience. I'll also discuss how wireless network monitoring can help you find a rapid solution. Dynamic Host Configuration Protocol (DHCP), which automates the process of allocating IP addresses to devices connected to the network, is an essential part of Wi-Fi (and networks in general). Devices cannot establish network connectivity without a proper IP address, which prevents them from connecting to the internet or interacting with other networked devices. Users can access websites and other network resources thanks to DNS (Domain Name System), which converts human-readable domain names into IP addresses. Web page access issues or intermittently sluggish performance are frequently caused by DNS configuration errors or unavailable DNS servers. For authentication, authorization, and accounting functions in WiFi networks, a RADIUS (Remote Authentication Dial-In User Service) server is frequently employed. Although RADIUS servers are crucial for company authentication, they occasionally pose problems for Wi-Fi users. Due to the characteristics of wireless communication and how broadcast packets are handled, Layer 2 broadcast traffic can affect wireless networks. Layer 2 collision domains are expanded to include the active channels in wireless networks. In fact, a single SSID that shares a subnet with a wired network can cause problems for all Wi-Fi users when numerous SSIDs are broadcasting from a single AP.
