Using iPerf3 to Test and Validate a Wireless Link

When troubleshooting or optimizing a wireless link, it is easy to look at the signal strength and assume everything is working properly. Signal levels are important, but they don't always tell the whole story. One of the tools I like to use is iPerf, because it lets you put actual traffic across the link and measure what the connection can really deliver. In this example, I was testing a Ubiquiti Wave Pro wireless link while it was being realigned. Rather than relying only on the radio's signal information, I wanted some real-world performance data to show whether the alignment changes were actually making a difference.

Your ChatGPT Chats Aren't Private — They're Turning Up as Evidence in Court

Here's an uncomfortable truth a lot of people haven't clocked yet: your late-night ChatGPT venting sessions, your "hey can you help me word this email to my ex" prompts, your half-formed legal or financial worries — none of that is protected the way a conversation with your lawyer, doctor, or therapist would be. A recent Washington Post investigation, picked up and expanded on by outlets like gHacks and TechSpot, found that AI chatbot conversations have already surfaced as evidence in at least 12 public court cases over the past two years. And that's almost certainly the tip of the iceberg, since most discovery material never becomes public record in the first place.

How to Test a Ubiquiti Product Using iPerf2

When you install or troubleshoot a high-speed wireless link, looking at the radio's signal strength and connection status only tells part of the story. The real question is simple: how much usable network performance can I actually get across the link? One of my favorite ways to answer that question is with iPerf. In this video, I demonstrate a real-world throughput test using iPerf2 across a Ubiquiti Wave Pro radio link. It is a simple test, but it provides much more useful information than simply looking at the radio's reported link speed. By generating actual TCP traffic between two endpoints, iPerf lets you measure the performance of the network path itself.

Closing the Dark Hours Security Gap

Executive Summary

Most organizations actively monitor their security environment during the roughly eight "light hours" of the business day. The remaining sixteen hours — plus weekends and holidays — represent the highest-risk, lowest-visibility window in the entire security posture. Bad actors know this, and they deliberately exploit these "dark hours" for reconnaissance, lateral movement, and data exfiltration precisely because defenders have reduced eyes on the network.

How Network Data and Signal Graphs Prove a Wireless Improvement Worked

When making changes to a wireless network, it is important to measure the results rather than simply assume the change was successful. A grest example is when I was working with a team aligning a pair of point to point Ubiquiti Wave Pro radios. An antenna may look properly positioned after an adjustment, but visual inspection alone cannot tell you whether the wireless link actually improved. Collecting radio and network performance data before, and after the change provides objective evidence and gives you a reliable way to determine whether the adjustment produced the expected result.
