I'm a network engineer looking for the best Wi-Fi analysis tool for diagnosing connectivity issues in an office building.

For an office-building network engineer, my top pick would be NetAlly AirCheck G3 Pro if your primary job is diagnosing real connectivity problems. If you also need detailed RF planning and predictive/site-survey work, I’d pair it with Ekahau or consider AirMagnet Survey PRO.

My shortlist

What I'd actually buy

If you troubleshoot existing enterprise Wi-Fi:
AirCheck G3 Pro. It's purpose-built for this job rather than being just a spectrum/SSID viewer. It can test the connection from the client perspective and also gives you spectrum, iPerf, packet capture, path analysis, and site-survey capabilities.

If you're responsible for both troubleshooting and Wi-Fi design:
Ekahau + Sidekick-class hardware is the more complete RF-engineering setup. It's the choice I'd lean toward for a large multi-floor building where you regularly redesign AP placement, channel plans, power levels, roaming, and capacity.

If budget matters:
Start with Wi-Fi Explorer Pro for software diagnostics and use AirMapper/AirCheck when you need proper walk-through measurements. NetAlly's AirMapper can generate heatmaps and measure SNR, noise, utilization and interference, including 6 GHz.

One important 2026 consideration: don't buy the old AirMagnet WiFi Analyzer expecting it to be a current product. NetAlly lists it as discontinued, with support ending December 31, 2025; it recommends AirCheck G3 Pro or EtherScope nXG instead.

My ranking for your specific use case:
1. AirCheck G3 Pro → troubleshooting
2. Ekahau → engineering/design
3. Hamina → design + modern workflow
4. AirMagnet Survey PRO → surveys/heatmaps
5. Wi-Fi Explorer Pro → inexpensive quick diagnostics

If you tell me Cisco/Aruba/Meraki/etc., approximate building size, Wi-Fi generation (6/6E/7), and whether your biggest problem is roaming, interference, coverage, or throughput, I can narrow this down to the best tool/setup for your environment.
