Troubleshooting a wireless network can be risky. Thanks to Wi-Fi analyzers for Windows 10, you can detect rogue access points and perform site surveys, among others. If you have managed a wireless network, then you know it is as crucial as the other assets of an organization. For that reason at least, it is important to keep an arsenal of tools at your disposal to troubleshoot Wi-Fi networks.
The best Wi-Fi analyzers for PC
NetStumbler is a classic utility for detecting 802.11 a/b/g WLANs. The program aids in the configuration verification and identifying poor signals. NetStumbler lets you:
- Verify that your network is set up the way you intended.
- Find locations with poor coverage in your WLAN.
- Detect other networks that may be causing interference on your network.
- Detect unauthorized “rogue” access points in your workplace.
- Help aim directional antennas for long-haul WLAN links.
- Use it recreationally for WarDriving.
Another free Wi-Fi analyzer tool is Wireshark, which boasts of its huge community of users as well as rapid updates. While it is best known for its Ethernet analysis, Wireshark also supports 802.11 and helps troubleshoot wireless problems and lock down security configurations.
Acrylic by Tarlogic Security comes in both free and premium versions. The Wi-Fi scanner supports a monitor and promiscuous mode to help you monitor network traffic. It also includes a brute-force password cracking function to test the strength of a password. It displays a list of SSIDs and their corresponding details at the top of the application window. It also displays WiFi access points and shows details of the security mechanisms and obtains generic WiFi passwords using a plugins system. The tool collects information from 802.11/a/b/g/n/ac networks.
- Access points: WiFi networks information (SSID/BSSID) and connected users.
- Signal level: Signal quality charts for WiFi channels and detected devices.
- Inventory: Naming known Wi-Fi devices.
- Passwords: WiFi passwords and default WPS Keys (password testing).
- Channels: WiFi channel scanner and WiFi networks through channels in 2.4Ghz and 5Ghz.
- Security: Network authentication and security details for WEP, WPA, WPA2 and Enterprise (802.1X) WiFi networks.
- Hardware: No special hardware is required for its operation.
NetSpot WiFi is among the popular Wi-Fi scanners for network management and troubleshooting. Originally available on Mac, the tool has recently come to the Windows platform, with support for WiFi 802.11 a/b/g/n/ac.
The tool lets you track all SSIDs linked to your network and manage them with ease. It displays all operating channels that connect with SSIDs, as well as all the SSIDs interacting with each other. It also works to monitor the signal strength.
NetSpot also locates and eliminates rogue access points, detects unauthorized workstations, avoids cross-channel interference, and gets rid of false-positive intrusion alerts. You can also check the security settings (Open, WEP, WPA/WPA2 Personal/Enterprise), non-broadcasting SSIDs and WiFi signal strength with the tool.

The tool is available to download from its website.
Wi-Fi Analyzer includes three tabs, namely Connected, Analyze and Networks. The Connected provides information about the current WiFi connection. It displays a graphic of the connection quality based on link speed and signal level in negative dBm at the top of the window. Also, there are icons that show bad link speeds, weak channel, poor connection, absence of internet connection, and unsecured connections.
The Analyze page lets you make changes to boost connection strength. It provides access to graphics and the channel ratings, lets you switch between channels, and allows you to toggle between the frequency bands. It also provides full access to customize the colors of the graphics and the SSID/MAC. Plus, there is an option to filter the SSIDs shown in the graphics according to signal bars, frequency band, overlapping, WiFi method, and network type.
The Network tab offers a list of all available SSIDs. It lets you filter the available connections according to their name and signal.
Wi-Fi Analyzer is available from the Windows Store for free.
