Wireless mesh networks may bring the dream of a seamlessly connected home or office into reality. Traditional networks rely on wired access points or wireless hotspots to connect users. In a wireless mesh network, the network connection is spread among wireless mesh nodes that “talk” to each other to share the network connection across a large area.
What are mesh nodes
Mesh nodes are small radio transmitters that function in the same way as a wireless router. Nodes use the common Wi-Fi standards known as 802.11a, b and g to communicate wirelessly with users, and, more importantly, with each other.
Are all mesh networks the same?
No, categorically not. There are no standards; every system is different and isn’t interchangeable, so once you’ve bought into one then you’ll have to stick with it or upgrade the whole lot.
However, there are broadly two types of system. There are those that take over from your router, such as the Netgear Orbi and Eero, and devices that work in conjunction with your router, only taking over Wi-Fi duties – such as the BT Whole Home Wi-Fi and Linksys Velop (Velop can actually work both ways).
How fast are they?
In our tests we found that a powerful router can reach speeds of 500Mbps+ at close range, dropping to around 300Mbps+ in an adjacent room (we’re talking about brick-walled homes) and to around 200Mbps from two rooms away.
In contrast, we’ve found that the fastest mesh routers can consistently deliver 300Mbps+ throughout a three-storey home.
Mesh network advantages
The first, and in many ways most crucial, is that despite having multiple nodes with multiple Wi-Fi signals, the whole mesh system unifies your Wi-Fi connection into one network name (known as an SSID).
The second advantage is that the system takes care of determining which signal is best for your devices to connect to. So, as you roam around your home, you do not have to worry about changing your Wi-Fi login from zone to zone.
Disadvantages of mesh networks
As an overall Wi-Fi system, most mesh routers have few downsides.
The first disadvantage is the increased latency. If you want to have the absolute fastest possible connection then the added latency of using not just Wi-Fi but an extended Wi-Fi signal may be a concern.
The second disadvantage is the limited functionality of the systems. If you’re buying a system that replaces your router then be aware that most of them don’t offer the advanced abilities of expensive conventional routers such as the ability to share USB devices like printers and hard drives.
In closing
Mesh routers are relatively new to the market but look set to become the de facto choice for many larger households. As such, we’ll likely see them diversify in the same ways as conventional routers.

Windows 11 Upgrade - Will it work on your lapop?
So, you’re wondering about Windows 11, the latest version of Microsoft’s operating system. It looks snazzy and has some neat features. But can your current laptop actually run it? Don’t worry, you don’t need a degree in IT to figure this out! We at abacon IT in Cape Town are here to help you understand the basics.
Upgrading your laptop to Windows 11 can give it a new lease on life. However, Windows 11 has certain system requirements. These are the minimum specifications your laptop needs to have to run the software smoothly. Think of it like needing the right ingredients for a recipe – without them, it just won’t work properly.
One of the most important parts is your laptop’s processor, often called the CPU (Central Processing Unit). This is the “brain” of your computer. Windows 11 needs a fairly recent and capable CPU to function well.
Which Processors Work with Windows 11?
Here’s a simplified look at the processors that are generally compatible:
Intel Processors:
- Generally, Windows 11 requires an 8th-generation Intel Core processor or newer. You might see names like “Intel Core i5-8xxx” or “Intel Core i7-11xxx.” The first number after the “i” (or “i3”) usually indicates the generation. So, an “i5-8250u” is an 8th-generation processor.
- Intel also has its Pentium and Celeron processors. For Windows 11, only certain newer models are compatible.
AMD Processors:
- For AMD, Windows 11 requires Ryzen 2000 Series and newer. You’ll see names like “AMD Ryzen 5 2xxx” or “AMD Ryzen 7 5xxx”. Again, the first number after “Ryzen” indicates the series.
- AMD also has Athlon processors. Similar to Intel’s Pentium and Celeron, only specific newer Athlon models will work with Windows 11.
Important Note: This is a general guideline. There can be exceptions, so it’s always best to double-check your specific processor.
How to Find Out Which Processor Your Laptop Has
Don’t fret, Windows makes it pretty easy to see what CPU is inside your laptop:
- Right-click the Start Button: This is the Windows logo (usually in the bottom-left corner of your screen).
- Select “System”: A new window will pop up with information about your computer.
- Look for “Processor”: You’ll find this listed under the “Device specifications” section. It will tell you the name of your processor, including the manufacturer (Intel or AMD) and the model number, which usually indicates the generation or series.
Once you have this information, you can compare it to the general lists above.
Other Important Bits for Windows 11
Besides the processor, there are a few other things Windows 11 needs:
- RAM (Random Access Memory): Consider this your laptop’s short-term memory. Windows 11 requires at least 4 gigabytes (GB) of RAM. More is always better for smoother performance. Instead, consider 16 gigabytes (GB).
- Storage: To install Windows 11, you’ll need at least 64 GB of free space on your hard drive or SSD (Solid-State Drive). An SSD generally makes your computer much faster.
- TPM 2.0 (Trusted Platform Module): This is a security feature. Most modern laptops have this, but it’s worth checking. You can usually find information on how to check for TPM 2.0 in your laptop’s BIOS settings (you might need to consult your laptop manufacturer’s website for instructions on accessing this).
- Graphics Card: Your graphics card needs to be compatible with DirectX 12 or later with a WDDM 2.0 driver. Most reasonably recent graphics cards will meet this requirement.
- Display: You’ll need a screen with a resolution of at least 720p (HD).
