Wifi Troubleshooting - Get Your Clients Perspective

When Wi-Fi performance complaints start rolling in, it's tempting to focus immediately on access points, controller dashboards, and network infrastructure. While those tools provide valuable information, they don't always tell the whole story. The most important viewpoint is often the one that's overlooked: the client's.

Microsoft Extends Free Windows 10 Security Updates Until October 2027

Microsoft has quietly announced welcome news for millions of Windows 10 users by extending its free Extended Security Updates (ESU) program for personal devices until October 12, 2027. The move gives home users an additional year of critical security updates beyond the previously announced deadline, providing extra time for those who have not yet transitioned to Windows 11. Rather than making a major public announcement, Microsoft updated its documentation and confirmed the extension in a statement following the discovery by BleepingComputer.

AryStinger Awakens: Thousands of D-Link Routers Hijacked in Global Botnet Campaign

 A newly discovered malware campaign known as AryStinger is serving as a stark reminder that aging network equipment can quickly become a cybersecurity liability. Researchers have uncovered a botnet that has compromised more than 4,000 outdated D-Link routers worldwide, transforming them into remotely controlled systems capable of carrying out malicious activities on behalf of cybercriminals. The affected devices are primarily older, end-of-life models that no longer receive regular security updates.

The Case for Bench Testing

There's a temptation in wireless PTP network deployment to skip straight to installation.
Go get the hardware mounted, cabled, and pointed at the horizon as fast as possible. But experienced field engineers know better. Bench testing before deployment isn't just a nice-to-have habit; it's a professional discipline that separates confident, successful rollouts from costly, frustrating ones. When you take the time to power up your equipment in a controlled environment first, you're investing in every stage of the deployment that follows.

The Commodore Callback 8020: A Flip Phone Designed to Break Your Social Media Habit

In a world where smartphones constantly compete for our attention, the newly announced Commodore Callback 8020 takes a radically different approach. Rather than packing in more apps, notifications, and AI-powered distractions, Commodore's latest retro-inspired flip phone is designed around the concept of a "digital detox." The Callback 8020 combines nostalgic early-2000s flip phone styling with modern hardware, offering users a way to stay connected without being trapped in an endless cycle of doomscrolling. The device runs Sailfish OS and supports many useful Android applications while intentionally blocking social media platforms, web browsers, email, and workplace productivity apps.

Lock, Stock, and Expired: Why Your PC's Boot Security Has a June Deadline

 

For most computer users, the words "cryptographic certificate" trigger about as much urgency as a terms-of-service update. But this month, a 15-year-old security keystone built into virtually every Windows and Linux machine is reaching the end of its life — and ignoring it could quietly leave your system's deepest defenses in the dark.

Starting June 24, three Microsoft-signed certificates that underpin Secure Boot will expire. Secure Boot is a UEFI firmware trust chain that verifies the digital signature of every component loaded during system startup, from firmware to the operating system. It runs before Windows even starts loading, checking that the boot loader and early boot components have been signed by a trusted party. Think of it as a bouncer at the door of your PC — one whose license is about to lapse.

The Trade-offs of Access Point-Driven RF Scanning

When a wireless access point is used to perform an RF (radio frequency) scan of its surrounding environment, it must temporarily or partially shift its radio hardware away from its primary role of serving client traffic. Most enterprise-grade access points operate in what is called "channel scanning mode" or leverage an integrated spectrum analysis engine, but in either case the radio must sweep across channels it is not currently serving. This creates an inherent tension: the same radio that is listening for interference on channel 11 is not, at that moment, beaconing or acknowledging frames on channel 6. For single-radio APs, this means client associations drop or degrade during the scan window. Even on dual- or tri-radio platforms, dedicating one radio to scanning reduces the available capacity for client load balancing or band steering, and the scanning radio's physical placement — fixed to a ceiling or wall — limits its ability to capture a spatially accurate picture of the RF environment from the perspectives that matter most, such as where a user is seated or where a device is roaming.

C0XMO: The Router Botnet That Doesn't Just Infect—It Eliminates the Competition

A newly discovered botnet called C0XMO is raising concerns across the cybersecurity community after researchers uncovered its ability to exploit vulnerable DD-WRT routers, spread across multiple device types, and aggressively remove competing malware from infected systems. Based on the well-known Gafgyt malware family, C0XMO targets a wide range of processor architectures, making it highly adaptable and capable of compromising routers, DVRs, Android-based devices, and other internet-connected equipment.

Wifi Auto Doesn't Mean Optimal - Things to look out for

Channel chaos: your AP is fighting neighbors it can't see

Auto channel selection sounds smart, but most vendors run a quick scan at boot time and picks a channel based on what's visible in that moment. It doesn't continuously adapt, and it can't account for non-Wi-Fi interference sources like baby monitors, microwaves, or Bluetooth clusters. In a dense apartment building or office, every AP is probably also running Auto — meaning everyone lands on the same "least busy" channel simultaneously. The result is coordinated co-channel interference that degrades throughput for everyone. A manually chosen, spectrum-

The Battle for Your Android: Why “Open” Still Matters

KeepAndroidOpen.org is a grassroots campaign focused on defending one of the core promises Android was built on: the ability for users to freely install and run the apps they choose. The site highlights proposed changes to Android’s developer verification system that could centralize control over app distribution under a single authority. According to the campaign, this shift risks turning an open ecosystem into a tightly controlled environment where even sideloaded or independently distributed apps would require prior approval. 

AVOID the malicious openew.app website

 

Based on current threat intelligence, I would treat openew.app as malicious and unsafe.

Several independent indicators point to it being a phishing/malware site:

• A recent security scan classified openew.app as a phishing site with a very low trust score and noted that 16 security engines flagged it. The domain was also only a few days old when analyzed, which is a common characteristic of malicious campaigns.
• Researchers at Malwarebytes reported that openew.app impersonates the official ChatGPT download page and delivers malware to both Windows and macOS users. According to their analysis, Windows users receive credential-stealing malware, while macOS users are served Atomic Stealer (AMOS), which targets passwords, browser data, and cryptocurrency wallets.
• Multiple malware sandbox analyses observed malicious behavior associated with downloads from the site and classified activity from the domain as malicious.

DHCP Detective: Looking for Sparks Before it Becomes a Fire

If there’s one thing every network admin learns the hard way, it’s that DHCP problems rarely announce themselves politely. One minute everything is fine, and the next users are wandering the office asking why Wi-Fi suddenly stopped working. That’s why proactive DHCP troubleshooting matters. Instead of waiting for a full-blown outage, keeping an eye on your DHCP logs can reveal warning signs long before devices start losing addresses and chaos begins. In this example, I will refer to  Ubiquiti EdgeRouters, since I'm working with them quite a bit lately. One of the best places to start is the trusty command sudo cat /var/log/dhcpmasq.log

FYI.  the same methodology and tips will apply to any DHCP server.
