To tackle these issues efficiently, professional engineers rely on powerful tools. One such tool, Ekahau AI Pro, has become a gold standard in the wireless industry for troubleshooting and optimizing Wi-Fi networks. This blog delves into troubleshooting wireless networks using Ekahau tools, providing practical examples and technical insights to guide professional engineers in improving network performance.

Futureproofing Our Security In our increasingly connected world, the security of digital information has never been more critical. From banking transactions to private communications, our data is constantly transmitted and stored across the internet. The current systems that protect this data rely on cryptography, a branch of mathematics that helps keep information secure by encoding it in ways that are difficult to decode without the proper key. However, with the rise of quantum computers, traditional cryptography is facing new and significant threats. This is where Post-Quantum Cryptography comes into play. What is Post-Quantum Cryptography? Post-Quantum Cryptography (PQC) [1] refers to cryptographic algorithms that are specifically designed to be secure against the power of quantum computers. Quantum computers, once they become practical, will be capable of solving complex mathematical problems much faster than classical computers. This will render many of the encryption methods we rely on today [such as RSA (Rivest, Shamir, and Adleman – initials of the inventors) and ECC (Elliptic Curve Cryptography)] vulnerable to attack. Quantum computers operate on quantum bits, or “qubits”, which can exist in multiple states simultaneously, unlike classical bits that are either a zer (0) or one (1). This allows quantum computers to perform certain calculations exponentially faster than classical computers. For example, in a matter of seconds, a quantum computer could potentially break an RSA key, which is considered secure by today’s standards. As quantum computing technology advances, the need for PQC becomes even more urgent.

Designing a Wi-Fi Network This is the first in a series of blogs on Wi-Fi operation, design, and troubleshooting. Designing a Wi-Fi network is much easier if you have the right procedures and tools in place. First you must collect data about the network: What are the requirements of the network? What is the goal of the new network? What is it meant to achieve? Are there any constraints you have to overcome? Next you have to decide what wireless vendor is being used? One of the most important things to get is an accurate map (or plan) of the site and the various floors.

Critical Component for Your Future In today’s ever-evolving tech landscape, staying ahead of the curve is crucial. IT certifications not only validate your expertise but also help open the doors to better career opportunities and advancement. Whether you’re just getting started, or looking to advance, certifications from industry leaders like Ubiquiti , CWNP , CompTIA , and Cisco can be game-changers for your career. Why IT Certifications Matter IT certifications are a proven way to prove your skills and knowledge to employers. As businesses increasingly rely on technology for daily operations, they need professionals who can navigate the complexities of IT infrastructure, networks, and security. A certification can give you a competitive edge, help you land higher-paying roles, and keep you on the cutting edge of the tech industry.

The Grim Realities of Transition Mode Summary of a recent experience relating to Transition Mode. I have been quite vocal of my hatred of Transition Mode (for WPA3). We have a solution for this - dual SSIDs: https://wifisecuritywizard.com/general/problems-with-wpa3/ IMHO - Transition Mode is dumb! Turn on WPA3, and for everything that doesn’t support it, create a second SSID for now... while you upgrade everything! I have actually said “it’s 2025 for goodness sake, how many devices do you have that don’t do WPA3?!” Well, the other day, the universe decided to mess with me... Scenario: in one of our smaller offices, we are upgrading to Ubiquiti. I arrive on site, I upgrade the system, 5GHz only WPA3, everything is working great! I do one last check, and one of the users mentions, “Oh, the Brother color laser printer isn’t working.” (It’s a nice little device. Prints really well. Cheap to run.)

An Important Task The IT industry is one of the most competitive and dynamic sectors in today’s swiftly evolving technology landscape. Whether you are a seasoned professional seeking to advance your career, or a newcomer seeking to enter into the field, obtaining IT certifications can have a substantial impact on your trajectory. However, earning certifications is not just about passing exams, an important factor is the study and practice that goes into getting ready to sit the exam. Training for IT industry certifications is a critical investment, offering both technical and professional benefits that can pay dividends throughout your career. Enhancing Technical Expertise At its core, IT certification training is designed to deepen your understanding of critical technologies and concepts. Whether it's network administration, design, cybersecurity, or analysis and optimization, each certification offers an opportunity to master a specialized area within the IT environment. By engaging in structured training programs, you not only learn the theoretical aspects of a technology but also gain hands-on experience in applying it to real-world scenarios. For example, pursuing certifications like CWNP’s Certified Wireless Network Administrator (CWNA), CompTIA’s Network+, or Cisco’s Certified Network Associate (CCNA) requires you to develop a solid foundation in network management, administration, and troubleshooting. This level of expertise is often beyond what you would learn on the job without formal training, giving you the ability to perform tasks more efficiently and with greater confidence.

In the IT profession, which is better: self-study or instructor-led training? You’d likely answer that self-study is cheaper... but, in the long run, is it? This blog compares the benefits and costs of deciding on a path to learning.
