WiFi Scanner

Boost Your Connection: Scan, Diagnose, and Fix Slow WiFi with Ease! Supports all WiFi technologies, including WiFi 6, WiFi 6E, and WiFi 7 (802.11be) networks.

Whether you are a professional looking for advanced technical information, a homeowner with a new WiFi setup or a student gathering information for a school project, WiFi Scanner is great to have handy. With WiFi Scanner you can scan and monitor signals in the air and see what wireless networks are around. Then run speed tests on any wireless network and view detailed information about its signal levels, channel width, encryption type, noise level and much more!

WiFi Scanner is fast, lightweight and easy to set up. See the review below from MacWorld.

"...your wireless router is fighting for spectrum with its neighbors, potentially slowing you down and making your Internet experience less pleasurable. ...WiFi Scanner helps you solve this problem by showing you all the access point(s) nearby, and suggesting the best configuration settings to get the most out of your router." -- MacWorld

WiFi Scanner is great for determining the best position for an access point at home or in the office. Once placed, the optimal channel can be found by picking the least used one, resulting in improved WiFi speeds.

Key Features

- Simple, fast wireless network discovery of 802.11 a/b/g/n/ac/ax/be access points
- Full support for 2.4, 5 and 6 GHz networks
- Support for all channel bandwidths (20, 40, 80, 160 and 320 MHz)
- See which channels actually overlap, counting every channel a radio covers rather than only the one it advertises
- Display detailed wireless network parameters: network name (SSID), signal level (RSSI), MAC address (BSSID), signal quality, channel, maximum data rate, encryption, WiFi generation and more
- Display changes in signal level over time in graphical form
- Filter detected networks by typing an expression, such as rssi >= -70 AND band == 5
- Group networks by access point, AP name, SSID, band, vendor, channel width, security or signal
- Give each access point a custom label
- Alerts that tell you when a network appears, a signal drops or a new BSSID joins your SSID
- Export results to comma separated value (CSV) files

WiFi Speed Testing

- Upload and download WiFi speed testing
- Test against public servers or against another Mac on your own network
- Auto run speed test when client roams to different access point
- Auto repeat speed test with wait time between tests

"Who's On My Network" (LAN Scanner)

- Fast IP scanner that detects unknown devices connected to your WiFi network
- Detects hostnames, determines the MAC address, and in many cases auto-detects device type (phone, laptop, router, etc.)
- Name any device yourself, and that name is what it is called from then on, surviving rescans and restarts
- Probe for open ports and services to identify the devices that stay quiet
- Scanning results can be saved to CSV or PDF via the export menu
- Great for finding WiFi "Piggybackers"

Advanced Features (supported by some access points)

- Display access point name if configured by network administrator
- Display number of devices connected to each access point
