In this part of the video, the speaker discusses the challenges of troubleshooting wireless networks due to their invisibility, introducing Wi-Fi analyzer tools as a solution. They highlight five Android Wi-Fi analyzer apps they use personally, starting with two similar ones: “Wi-Fi Analyzer Open Source” (free) and “Wi-Fi Analyzer” (free and paid). These apps provide four key types of information: lists of access points with details (e.g., signal strength, channels, distances), channel graphs to see channel utilization, channel ratings to identify the best channels for minimal congestion, and time graphs to monitor signal strength changes over time for troubleshooting. Additionally, the speaker mentions that this video is not sponsored and plans to update the list of tools annually. In the next video, the speaker will cover Wi-Fi analyzers for iPhone.

In this part of the video, the speaker discusses the pros and cons of the Net Analyzer app. They mention that while the free version displays ads, the pro version, which is not free, removes the ads and offers additional features. The app is useful for network analysis, including scanning connected devices. The speaker recently used it to locate the IP address of a Raspberry Pi on their network. The app also includes tools like ping, trace route, port scanner, and DNS lookup, which can be handy on a mobile device. However, a major downside is that the app hasn’t been updated since September 2022, raising concerns about security and lack of support for newer Wi-Fi features. Therefore, despite the positive overall experience, the speaker hesitates to recommend purchasing the pro version without recent updates.

In this segment of the video, the speaker discusses two apps for Wi-Fi management. The first app, Wi-Fi Man, is free and ad-free, providing features such as displaying access points, performing LAN scans, internet speed tests, and showing network latency. It can also track Wi-Fi signal strength in different house locations and scan the house using the smartphone’s camera to create a floor plan, although the speaker had difficulty using this feature.
The second app, Speed Test Wi-Fi Analyzer, has both free and paid versions. The free version includes features similar to Wi-Fi Man but with more details. It also offers an advanced speed test, wireless coverage analyzer, ping and DNS speed analyzer, and a Wi-Fi handover analyzer. The paid version adds more advanced functionalities, such as decoding Wi-Fi scans and showing beacon frames, which provide detailed wireless network information.
