WiFi & LAN Utils

WiFi & LAN Utils shows what is happening on your Wi-Fi: which networks are nearby, which channels are crowded and which devices are connected to your router. Everything runs locally on your phone — no account, no cloud, no analytics.

WI-FI ANALYSIS
• Nearby networks, including hidden ones: signal strength, 2.4 / 5 / 6 GHz band, channel and channel width (20–320 MHz)
• Wi-Fi 4, 5, 6, 6E and 7 standards
• Access point vendor from the IEEE registry
• Security: WPA3, WPA2, WPA, WEP, open networks, WPS and Protected Management Frames (PMF)
• Group by network name (mesh, multiple access points), filters, sorting and search
• Export results to CSV and JSON

CHANNELS
• Channel graph for every band showing overlapping networks
• A 0–10 score for every channel
• Channel recommendation for your router

SIGNAL
• Signal strength over time for selected networks — helps you find the best spot for your router

CURRENT CONNECTION
• Network name, signal, link speed, band and channel
• IP address, subnet mask, gateway, DNS servers, IPv6 and MTU
• Security assessment of your network with concrete advice
• Public IP address and Internet provider (only on request)
• Check whether UPnP is enabled on your router

DEVICES ON YOUR NETWORK
• Local network scan: router, phones, computers, TVs, printers, NAS, speakers, cameras and smart home devices
• Device type, manufacturer and model detection (mDNS, UPnP, NetBIOS, DNS)
• Open ports with warnings about risky services (Telnet, SMB, RDP and more)
• Device history: first and last seen, new devices highlighted
• Custom names and types, mark devices as trusted
• Export the list to CSV and JSON

TOOLS
• Ping: latency, jitter and packet loss
• TCP port scanner for your own devices
• DNS lookup: A, AAAA, MX, TXT, CNAME, NS, PTR and SOA using the server of your choice

PRIVACY
• All data stays on your device
• No account, no ads, no analytics SDKs
• The app contacts external services only when you explicitly ask (for example the public IP lookup)

PERMISSIONS
• Location: Android only returns Wi-Fi scan results and the name of your network to apps with location access. WiFi & LAN Utils never stores or sends your location.
• Nearby devices / local network: needed to scan Wi-Fi and to discover devices on your network.

Note: Android limits apps to 4 Wi-Fi scans per 2 minutes. The app shows the remaining budget and explains how to turn off the limit in Developer options.

Only scan networks and devices that you own or are authorized to test.
