Samsung's hidden Connectivity labs menu offers advanced Wi-Fi tools on Galaxy S20 and newer models, including signal inspection, smarter switching, and low latency protocols, which can significantly improve connectivity and network performance when accessed and configured properly.
Wi-Fi routers have several features that can improve network security, experience, or both. These include automatic updates, Quality of Service (QoS) rules, guest networks, bandwidth monitoring, custom DNS servers, VPN servers, Dynamic DNS (DDNS), parental controls, router-level speed tests, and Ethernet connections. Upgrading to a newer router is recommended if your current one is over 3-5 years old and doesn't support these features.
