What's the best Android app for diagnosing and troubleshooting Wi-Fi or mobile network problems?

V2Box is a comprehensive network utility app designed for users who need to diagnose and fix connection issues without requiring multiple separate tools. Its primary strength lies in consolidating various network diagnostics into a single interface, making it suitable for scenarios like identifying why a home Wi-Fi is dropping packets or why mobile data feels sluggish in a particular area. Key features include a visual ping monitor, a detailed bandwidth speed test, and a network information panel that displays real-time data on signal strength, IP configuration, and data usage. The app also offers a LAN scanner to see connected devices, which is useful for spotting unauthorized connections on a home network. While the interface is functional and data-rich, some users note it can feel a bit technical for absolute beginners. Reviews indicate that individuals managing small office networks or tech-savvy home users find the most value in its detailed readouts. The ad-supported free version provides core functionality, though power users might consider the paid option to remove ads and unlock advanced logging features. For a straightforward way to move beyond simply resetting a router when problems arise, V2Box delivers actionable insights.
