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.

EU Just Slapped ChatGPT, Reddit, and Roblox With Its Toughest Tech Rules — Here's What It Actually Means

If you've been following the EU's crackdown on Big Tech, add three new names to the list: ChatGPT, Reddit, and Roblox. On August 31, 2026, the European Commission officially designated ChatGPT as a Very Large Online Search Engine (VLOSE), while Reddit and Roblox got tagged as Very Large Online Platforms (VLOPs) under the Digital Services Act (DSA). This isn't a lawsuit or a fine — it's a regulatory classification, but it's the kind that comes with serious strings attached. All three services crossed the DSA's magic number of 45 million average monthly EU users, which is the trigger threshold for landing in this "top tier" of oversight alongside giants like Google Search, YouTube, TikTok, and Meta's platforms. That brings the EU's VLOP/VLOSE list to 28 services total.

Internet Protocol Journal: IPv6, Internet Geolocation, and the Future of Network Security

If you're interested in networking, Internet protocols, or the technology that keeps the modern Internet running, the latest issue of the Internet Protocol Journal is definitely worth a look. The current edition is Volume 29, Number 2, September 2026, and it focuses on several topics that should be familiar to anyone working with networks today. The issue includes articles on IPv6, Internet geolocation, cybersecurity, and a review of the NIST Cybersecurity Framework 2.0.
