WiFi Analyzer: Speed & Signal

WiFi Analyzer shows what is really happening on your Wi-Fi: which networks crowd your channel, how strong your signal is in every room, and whether the Wi-Fi or your internet plan is what slows you down.

★ SEE EVERY NEARBY NETWORK
• Channel graph for 2.4 GHz, 5 GHz and 6 GHz: every access point drawn over the channels it really occupies, at its real width (20 to 320 MHz).
• Name, signal (dBm), channel, width, security (WPA3, WPA2, WPA, WEP, open) and Wi-Fi generation for each network.
• Weak security flagged: open, WEP and WPA-TKIP networks are marked.

★ FIND THE BEST CHANNEL FOR YOUR ROUTER
• A 0–10 rating for every channel, from the real signal of the networks around you, not just a count.
• One clear recommendation: 1, 6 or 11 on 2.4 GHz, non-DFS channels first on 5 GHz, PSC channels on 6 GHz.
• "Your channel 6 is busy (3/10). Channel 11 is quieter (8/10)" — then change it in your router settings.

★ SIGNAL METER
• A big live signal ring refreshed every second, with weakest, strongest and average readings.
• Optional beep that gets faster as the signal gets stronger: walk around and find the best spot for your phone, TV or mesh node.

★ ROOM SURVEY
• Measure each room in 3 seconds: signal, link rate and ping. Rooms are ranked and dead spots get a clear fix.

★ WHO'S ON MY WI-FI
• See every device on your network, with the router and this phone marked. Pro adds device types (printer, TV, camera, computer…), open ports and new devices since the last scan.

★ WI-FI SECURITY CHECK
• Is your network on WPA3, WPA2 or something weaker? Is WPS on? How many open or WEP networks are around you?

★ WI-FI OR INTERNET?
• Compares your last speed test with the Wi-Fi link rate and tells you which one is the limit.

★ REAL SPEED TEST INCLUDED
• Download, upload, ping, jitter and latency under load (bufferbloat), on Cloudflare's global network.
• Connection Doctor explains slow results and how to fix them.
• History with Wi-Fi / mobile filters, network info, ping monitor, DNS benchmark, browsing and streaming tests.

★ PRIVATE BY DESIGN
• No account. Scans and results stay on your phone; nothing is uploaded.
• Location permission is used only because Android requires it to list nearby Wi-Fi networks.

★ PRO (optional)
• Export every Wi-Fi scan as CSV, unlimited saved room surveys, device details, unlimited history, trends, scheduled tests, widgets, server choice and no ads.
• Monthly, quarterly, yearly or one-time lifetime. Or watch one short video for a 2-hour Pro Pass.
