WiFi Analyzer & Who's on WiFi

TecDroid Developer

About this app

WiFi Analyzer shows who is on your Wi-Fi, why it may be slow, and how to fix it in your router. A network scanner finds the devices that answer on your home network, names them as clearly as it can, and can tell you when a new one joins. Device names, labels and history stay on your phone.

WHO IS ON MY WIFI
• Scan your Wi-Fi and see the phones, computers, TVs, printers, cameras and smart-home devices that answer on the network
• Names, makers and models from Bonjour (mDNS), UPnP, NetBIOS and your router's own device names
• MAC address and maker when a device shares it; randomized "private" addresses are labelled as private, never guessed
• Give devices your own names, icons and owners, and mark them as known
• Optional new-device alerts for your home Wi-Fi, checked every 15 to 60 minutes
• See when each device was online, and export your device list to CSV or JSON

REMOVE A DEVICE, THE REAL WAY
Android apps can't disconnect other devices; only your router can. So the app:
• Opens your router's admin page inside the app, with the gateway found for you
• Shows step-by-step guides for common router makers: block, MAC filter, pause or parental controls
• Looks up the default router login for many router makers
• Helps you change your Wi-Fi password, then share the new one as a Wi-Fi QR code
• Opens your router maker's own app when you have it

WIFI ANALYZER: SIGNAL AND CHANNELS
• Live WiFi signal strength in dBm with plain words, and a walk mode with sound to find weak spots
• Nearby networks on 2.4, 5 and 6 GHz, with Wi-Fi 6, 6E and 7 details on phones that support them
• Channel graph with your network highlighted and others dimmed, plus focus on one network
• Channel rating and a plain suggestion for a less crowded channel
• Signal over time, and a room check to compare rooms and find dead zones

NETWORK TOOLS
Beyond the WiFi analyzer, a set of network tools:
• Ping (ICMP and TCP) with loss and jitter, traceroute, DNS lookup
• Port scan for devices on your own network
• Wake-on-LAN, IP and subnet calculator, offline MAC vendor lookup

SECURITY CHECK
• Your network's encryption (open, WEP, WPA, WPA2, WPA3), whether WPS is on, and how many unknown devices you have, with plain steps to fix each one

WIDGETS AND SHORTCUTS
• Network and devices widgets, a Quick Settings tile to scan, and app shortcuts

PRIVATE BY DESIGN
• No account. Device names, labels and scan history stay on your phone
• Location permission is asked only when you open nearby networks or Wi-Fi names, because Android requires it for Wi-Fi scans. Your location is never stored or sent, and the app never uses location in the background
• Crash reports and basic usage statistics (Google Firebase) never include network names, addresses or device names; analytics can be turned off

GOOD TO KNOW
• Some devices sleep or hide from scans, so your router's own list is the final word
• Android allows about 4 Wi-Fi scans every 2 minutes; the app shows a countdown instead of a frozen graph
• The app can't show saved Wi-Fi passwords, and it can't block devices by itself
• Use the network scanner and port scan only on networks you own or may test
