The Case For Nmap Ping Only Subnet Scans

Ever wonder which devices are actually alive on your network without calling up IT and asking for a census That’s where a simple Nmap ping scan comes in handy. 

By running a quick `nmap -sn -n 10.99.10.0/24`, I can get a list of all devices, response time and mac addresses that responded to my ping, no name resolution, no frills, just the facts. It’s like taking attendance in your network classroom—except the students don’t spend extra time proving their full name, and you don’t have to worry about someone doodling on the chalkboard.

When to Break Out the Spectrum Analyzer

Ever wondered what really lurks in the airwaves around you? In this lively webcast recap, Dan Jones walks us through the magic behind spectrum analysers — the tool that turns unseen RF chaos into visual clarity. If you’ve ever tried to design or troubleshoot a Wi-Fi network, you know it’s not just about access points and antennas; you’ve got to understand the jungle of interference, noise, and signal strength that lives between 2.4 GHz, 5 GHz and beyond. This session demystifies how spectrum analysers measure that energy and why it matters.

But it’s not just theory. You’ll learn the real-world when: measuring noise floors to predict actual data rates, spotting rogue interference sources, and making smarter planning decisions. From crowded office environments to industrial floors with noisy gear, this webcast shows how and where spectrum analysis earns its keep — and where modern smart APs handle most of the heavy lifting on their own.

Don’t Ghost Your Wi-Fi. Why Post-Deployment Checkups Matter

Rolling out a new Wi-Fi network feels like crossing the finish line, but in reality, it’s more like the halfway point. Following up after deployment is where the real value shows up. It’s your chance to confirm that access points are behaving the way you intended, coverage is consistent, and users are actually getting the performance you designed for. Without that follow-up, small issues can quietly grow into big complaints later.

In the image I shared, it’s pretty obvious that users aren’t evenly distributed across the access points. One AP looks loaded while others are just hanging out, bored and underutilized. That imbalance might be due to AP placement, building layout, or client devices stubbornly sticking to a stronger-looking signal. Even if it’s “technically working,” it’s still worth digging into because uneven client distribution can tank performance for everyone connected to the busy AP.
