Best apps for 6 GHz Wi-Fi scanning on Android in 2026
Six GHz is a different beast. Shorter wavelengths mean higher throughput and lower interference, but they also stop dead at drywall in a way 2.4 GHz signals never do. Move a Wi-Fi 6E router two rooms away and speeds drop from 1200 Mbps to 40 Mbps, and your phone will not tell you why unless you install a scanner that speaks 6 GHz.
We walked seven scanners around a two-story house with a Wi-Fi 6E router on the ground floor, marking dead zones on graph paper. Every app on this list detects channels 1U through 233 (the 6 GHz plan), reports RSSI, and helps decide whether the fix is a mesh node, a repositioned router, or an ethernet drop.
What to look for in an Android Wi-Fi scanner
- Explicit 6 GHz channel readout. Some older apps still cap at 5 GHz.
- Live signal graph with dBm history, not just a static bar.
- Channel-congestion view, so you can see who else is stepping on your channel.
- Site survey mode with waypoints, for room-by-room mapping.
- Access-point identification (MAC, vendor, standard) to spot rogue devices.
- Optional export (CSV, KML) so a network diagram is more than a screenshot.

The apps
1. WiFi Analyzer (farproc) — Best free channel graph
WiFi Analyzer from farproc has been the default answer for a decade, and the 6 GHz upgrade landed in a 2024 release. Channel Graph shows RSSI over time per SSID, Channel Rating suggests the least-congested channel, and the Signal Meter beeps louder as you walk toward the router. Free, no ads on Android 12+.
Where it falls short: Location-permission changes on Android 13 and later mean the app cannot show SSIDs from other networks unless you grant precise location. Save/export is not built in.
Pricing:
- Free: Full app.
- Paid: None.
Platforms: Android 5.0 and up.
Bottom line: Install this first. Nine out of ten Wi-Fi problems reveal themselves inside Channel Graph.
2. NetSpot — Best for room-by-room heatmaps
NetSpot is the Android side of the desktop survey tool. Import a floor plan (JPG or PNG), walk each room tapping “measure here”, and NetSpot builds a heat map showing where 6 GHz drops below usable strength. Compare snapshots taken before and after moving the router.
Where it falls short: The Android version does more than it did a year ago, but the deep analysis (multi-band overlay, capacity planning) still lives on desktop.
Pricing:
- Free: One survey, limited zones.
- Paid: $9.99/year Pro tier for unlimited surveys.
Platforms: Android 8.0 and up.
Bottom line: Pick NetSpot when the question is “where should the mesh node go”, not “what channel am I on”.
3. WiFiman — Best for Ubiquiti gear and independent networks
WiFiman from Ubiquiti works on any router but shines on UniFi setups. It reads AP model, PoE draw, channel width, and gives an unusually accurate signal-to-noise readout for 6 GHz APs.
Where it falls short: Some advanced telemetry needs a UniFi controller reachable on the LAN.
Pricing:
- Free: Full app.
- Paid: None.
Platforms: Android 8.0 and up.
Bottom line: Free, capable, and the right choice for anyone running Ubiquiti gear.
4. WiFi Analyzer Pro — Best extended graphs and site survey
WiFi Analyzer Pro (by VREM Software Development) extends the farproc classic with a site-survey grid, hidden-SSID detection, and CSV export. On 6 GHz, the channel graph shows PSC (Preferred Scanning Channel) markers so you can pick a channel roaming clients will actually find.
Where it falls short: The Pro upgrade nag is persistent. Some older phones lack the WPA3 stack the app needs for full 6 GHz reporting.
Pricing:
- Free: 7-day trial.
- Paid: $4.99 one-time.
Platforms: Android 9.0 and up.
Bottom line: Worth the five dollars if you need PSC markers and export.
5. NetX Network Tools — Best for full LAN inventory plus Wi-Fi
NetX rolls a Wi-Fi analyzer into a network scanner. Beyond channel graphs, it lists every device on the LAN with MAC, vendor, hostname, and last-seen time. Handy when you finally get 6 GHz sorted and realize a smart bulb is holding the whole network back on 2.4.
Where it falls short: Pro tier gates arp scan speed adjustments and unlimited saved networks.
Pricing:
- Free: Standard scans, ads.
- Paid: $2.99 one-time Pro.
Platforms: Android 5.0 and up.
Bottom line: For the moment you want to identify every device on the LAN, not just the AP.
6. Speedtest by Ookla — Best for real-world Mbps per location
Speedtest by Ookla is the app you actually use to confirm the fix. Walk the house running quick 5-second tests against the LAN Ookla server; save the results per room. On 6 GHz, the difference between a good spot and a bad spot is 900 Mbps or more, which no signal-strength app conveys as clearly.
Where it falls short: Wi-Fi bottleneck is often the LAN, not the internet uplink. The app measures both, but the labels can confuse non-network people.
Pricing:
- Free: With ads.
- Paid: $2.99/year Premium removes ads and adds video/audio tests.
Platforms: Android 6.0 and up.
Bottom line: The reality check for every scan another app runs.
7. OpenSignal — Best crowd-sourced coverage overlay
OpenSignal shines outside the house. It layers your walking test on top of a crowd-sourced map so you can see where nearby 6 GHz networks are stronger or weaker than yours. Useful when you are testing outdoor coverage or picking a spot for a garden AP.
Where it falls short: Cellular focus can crowd out Wi-Fi diagnostics. Sample sizes for 6 GHz are still thin outside major cities.
Pricing:
- Free: Full app.
- Paid: None.
Platforms: Android 7.0 and up.
Bottom line: For garden and yard planning, not indoor room-by-room work.
How to pick the right one
- If you have never run a Wi-Fi scanner: install WiFi Analyzer (farproc) first. Free and does 80% of the job.
- If you need a heat map on a floor plan: NetSpot on Android for capture, its desktop app for analysis.
- If you own Ubiquiti hardware: WiFiman is faster and richer than anything else.
- If you want PSC channel markers and CSV export: WiFi Analyzer Pro is worth $4.99.
- If you also want a LAN inventory: NetX rolls both into one.
- If the fix works, confirm with Speedtest by Ookla in each room.
- If you are planning outdoor coverage: OpenSignal for the crowd data.
Six GHz penalises poor placement more than 5 GHz ever did. A one-time scan tells you whether the router needs to move, whether you need a mesh node, or whether it is finally time to run an ethernet drop.
FAQ
Does my phone even support 6 GHz scanning?
Any phone shipped with a Wi-Fi 6E chipset (Samsung S21 FE 5G, Pixel 6 Pro and up, most 2023 flagships) sees the 6 GHz band. Older phones will list only 2.4 and 5 GHz networks.
Why do 6 GHz signals die at walls?
Shorter wavelengths lose more energy to absorption. That is the same tradeoff that makes 6 GHz less crowded: nobody else’s signal reaches your house from the street either.
What is a PSC and why does it matter?
Preferred Scanning Channels are the 15 channels a roaming Wi-Fi 6E client actually probes for a new AP. Broadcasting on a non-PSC channel means clients take longer to find your network.
Do I need to disable 2.4 GHz to use 6 GHz?
No. Modern routers broadcast all three bands under one SSID and steer clients. If your phone insists on the 2.4 GHz radio, that is a client-side steering bug, not a router config problem.
Will a Wi-Fi 7 router help my 6E phone?
Wi-Fi 7 features (MLO, 320 MHz channels) only work when both ends support the standard. A 6E phone on a Wi-Fi 7 router runs at 6E speeds. That is still enough to saturate a home fiber uplink in most cases.
