More than 230 different models of Cisco Wi-Fi access points may be writing 5MB a day of nonessential data, filling their onboard flash memory to the point at which they lack space for future software updates.

"If the router Conditional Approval process follows a similar pattern, Chinese-origin manufacturers like TP-Link may face a presumptive denial, while companies with manufacturing in allied nations like Taiwan, Vietnam, or South Korea could find an easier path."

The pop-up covering a sizeable chunk of the billboard makes it clear that a PC is lurking behind the scenes, raising questions about network security and management.

A router is the hub that sends internet traffic from the modem to every connected device. Even with a fast plan, an outdated or weak router can throttle home internet speed, causing buffering, lag, and slow loading times. This often shows up when multiple people stream, game, or join video calls at the same time.

But that's not the case everywhere. Here in the UK, the rules for telecommunications providers are set by Ofcom (the Office of Communications), and they're pretty simple -- your hotspot should work like your phone. No limitations, no nonsense. But when I'm not in the UK, things get... more complicated. Even in Europe, which has "Roam Like at Home" rules, there are usually hurdles such as speed caps and "fair use policies" to contend with.

I see a lot of people referring to Firewalla hardware as a firewall or security tool, and while that's correct, it also offers so much more. Think of the tech as having your very own personal network administrator, making even complex networking tasks as simple as flicking a virtual switch.

For years, iPhone users were locked out of the Meshtastic + TAK combination entirely. ATAK runs on Android. The plugin architecture Apple uses doesn't allow external plugins the way Android does. iOS users were told to buy an Android device or sit this one out. That changed in February 2026.

Long-range radio waves can pass through obstacles more easily, which makes them perfect for monitoring expansive factories or outdoor infrastructure. A recent report by Fabrity highlighted that these systems use very little power. This allows sensors to operate for 5 to 10 years on a single battery. Using such tech means you do not have to install expensive wiring across your entire site.

We live in a time where privacy is something we actually have to work to enjoy. Achieving a level of privacy we once had takes work, and you need to start thinking beyond a single desktop, laptop, tablet, or phone -- all the way to your LAN. Before I scare you all off, understand that this starts on the desktop and extends to the LAN. By beefing up both your devices and your network, you'll achieve a level of privacy that you wouldn't otherwise have.

Edge computing is a type of IT infrastructure in which data is collected, stored, and processed near the "edge" or on the device itself instead of being transmitted to a centralized processor. Edge computing systems usually involve a network of devices, sensors, or machinery capable of data processing and interconnection. A main benefit of edge computing is its low latency. Since each endpoint processes information near the source, it can be easier to process data, respond to requests, and produce detailed analytics.

In-flight Wi-Fi is roughly on par with hotel or airport Wi-Fi. It's not automatically unsafe, but it's not something you should blindly trust either. You're on a shared network with hundreds of other people, and you don't know how well it's segmented or monitored.

I'm blown away that I can write data to a little chip and then access that using a phone or tablet. I've embedded NFC tags into all sorts of things, from documents to business cards to 3D-printed objects. And it's easy! What you'll need You need two things: NFC tags: These come in all sorts of shapes and sizes, from to to .

Originally developed by Nest (before the Google acquisition), Thread has existed since 2011. Devised as a power-efficient mesh networking technology for internet-of-things (IoT) products, Thread gathered pace after the 2014 formation of the Thread Group, which develops the technology and drives its adoption as an industry standard. Founding members like ARM, Samsung, Google, and Qualcomm have been joined by Apple, Amazon, and many other big companies over the years.

The packaging immediately signals that RAK took this seriously. Everything is clean and thought-out, you open the box and you get the device, a charging cable, and a lanyard. That lanyard might seem like a small detail, but it comes included at the same price point as other EDC-style devices. In other words, this isn't a cost-cutting compromise or a cosmetic extra, it's a well-considered, user-focused design choice.
