Here’s a look at some of the top certifications that can elevate your career:



When it comes to wireless networking, CWNP (Certified Wireless Network Professionals) is the name to know. CWNP offers a series of certifications that cover everything from basic wireless networking to advanced security and troubleshooting.

  • Certified Wireless Network Administrator (CWNA): This foundational certification covers the fundamentals of wireless networking and is perfect for those who want to start their journey in wireless technology.
  • Certified Wireless Security Professional (CWSP): If you’re focused on wireless security, CWSP is the certification for you. It dives deep into wireless security protocols and best practices to keep networks safe from threats.

With the rise of IoT devices and the increasing reliance on wireless technology, CWNP certifications ensure that you have the skills needed to manage and secure networks in a wireless-first world.



CompTIA certifications are some of the most widely recognized across the IT industry. Whether you're fairly new to IT, or are an experienced IT professional, CompTIA offers certifications that cover a broad range of areas including network management, cybersecurity, and more.

  • CompTIA Network+: For those looking to specialize in networking, the Network+ certification validates your knowledge in network architecture, operations, and security.
  • CompTIA Security+: As cybersecurity becomes a top priority for organizations, this certification proves your understanding of risk management, encryption, and network security fundamentals.

CompTIA’s certifications serve as great knowledge verification for anyone in IT, to prove you “have what it takes”, and they help keep your skills fresh as technology continues to evolve.



When you think of networking, Cisco is likely one of the first names that come to mind. Known for their top-tier networking solutions, Cisco also offers a variety of certifications that can solidify your position as a networking professional.

  • Cisco Certified Network Associate (CCNA): This entry-level certification is essential for anyone working with Cisco networking equipment. Among other concepts, it covers networking fundamentals, IP services, and security basics.
  • Cisco Certified Network Professional (CCNP): As you advance in your networking career, Specialist or CCNP(professional)-level certifications are the next step. These certifications dive deeper into routing and switching, security, and network troubleshooting.

Cisco’s certifications are respected globally, and earning one can help you stand out in a competitive job market, especially in networking and systems administration.

Wi-Fi Myth Series - Myth #7: Roaming Problems are Always Client Problems

By Rie Morgan • July 23, 2026
Few phrases trigger a knowing smile from experienced Wi-Fi engineers quite like this one, "It's the client's fault." Someone's video call drops while walking through the office or a warehouse scanner pauses between aisles, voice handsets crackle as users move from one floor to another... then, almost immediately, someone points at the device and confidently declares, "Well... clients decide when to roam." Technically, they're correct. But, practically, that's only part of the story. Roaming is one of the most fascinating aspects of Wi-Fi because it isn't controlled by a single device or a single setting. It's a partnership between the client, the infrastructure, and the RF environment. When that partnership breaks down, blaming one side rarely tells the whole story. Let's bust another myth... Yes, Clients Make the Decision Let's start with the important truth: in almost every Wi-Fi deployment, the client device ultimately decides when to leave one AP and join another. Laptops, smartphones, tablets, barcode scanners, medical devices, and countless IoT products all use their own roaming algorithms. Some roam aggressively whereas some cling to their current AP for far too long. Others seem convinced that losing the connection entirely is preferable to switching. Every Wi-Fi engineer has encountered at least one stubborn client that appears almost “emotionally attached” to a particular AP. :) Client behavior matters, but that's not where the story ends.

Wi-Fi Myth Series – Myth #6: A Site Survey Is Optional

By Rie Morgan • July 17, 2026
Every Wi-Fi engineer has heard some version of it, "Can't we just install the access points where the old ones were?" Or perhaps, "The floorplan looks straightforward. Let's save some time and skip the survey." Occasionally, someone even says the dangerous words, "We've done hundreds of these buildings. They're all basically the same." That's usually the point where experienced wireless engineers quietly smile, knowing that the building is about to teach everyone a valuable lesson because: buildings don't read design guides, concrete doesn't care about your deployment schedule, metal doesn't respect your project budget, and radio waves have never once agreed to cooperate, simply because everyone wanted them to. Let's talk about why a site survey isn't an optional luxury... it's one of the most valuable engineering tools available. Every Building Is Different At first glance, two office buildings may appear identical: same square footage, same number of floors, similar room layouts, yet their wireless behavior can be dramatically different: one may have reinforced concrete walls, another may contain extensive glass partitions, the warehouse may be filled with moving inventory, a hospital may have elevators, imaging equipment, and countless reflective surfaces, a manufacturing facility may contain machinery that wasn't mentioned on any floorplan, and remember: even furniture changes RF behavior! Anyone who has performed enough surveys eventually develops a healthy respect for one simple fact: the building always gets a vote, too!

Wi-Fi Myth Series - Myth #5: Wider Channels Always Mean Better Performance

By Rie Morgan • July 13, 2026
There is something wonderfully satisfying about seeing a Wi-Fi channel get wider: twenty megahertz becomes forty. Forty becomes eighty. Eighty becomes one hundred and sixty. This begs the question: more bandwidth must mean more speed... right? Well... sometimes. Like many things in Wi-Fi engineering, the answer begins with, "It depends." The idea that wider channels always deliver better performance has become surprisingly common. It's an understandable conclusion because, in theory, wider channels can carry more data. More lanes on a highway should allow more traffic to flow. But Wi-Fi isn't driven by theory alone. The RF environment has an annoying habit of reminding us that physics always gets the final vote. Let's explore why bigger isn't always better... More Lanes... But Fewer Roads Imagine a city with only a handful of highways. If you combine four lanes into one giant superhighway, each individual vehicle might travel faster. Unfortunately, you've also eliminated several independent routes that other drivers could have used. That's exactly what happens with channel bonding: - An 80 MHz channel occupies the same spectrum as four adjacent 20 MHz channels. - A 160 MHz channel consumes eight. While you've increased the potential throughput available to one transmission, you've dramatically reduced the number of separate channels available for everyone else. In an empty environment, this is often perfectly acceptable. But, in a busy enterprise? Not so much.
