Wi-Fi problems are some of the trickiest to troubleshoot. Having the right tool for the job matters when connectivity is fickle and fleeting. After spending a few years consulting and troubleshooting for wireless, I’ve found these four tools to be valuable in my Wi-Fi kit.

WLAN Pi M4+

The WLAN Pi M4+ tool is the Swiss Army knife for Wi-Fi troubleshooting. It consists of a prebuilt Raspberry Pi box with a wireless card and adjustable modules. Updates are done by the community, for the community. It has various preloaded applications, such as Kismet, a client profiler and Grafana.

My favorite way to use WLAN Pi M4+ is for remote captures. The tool uses Power over Ethernet, so you can either plug it into a PoE-capable port on a switch or a power injector. The M4+ version also has the option to power via USB-C. From there, you can use Wireshark, Airtool or the Linux terminal to capture frames.

If those aren’t enough features, WLAN Pi M4+ includes a hotspot mode to spin up an AP and a server mode for services such as Dynamic Host Configuration Protocol. Among the Grafana profiles, the tool has a Wi-Fi scanner, internet monitoring and WLAN Pi health dashboards
