What Is DNS and How Does It Work?
Every time you open a site, a short conversation happens first. It takes milliseconds, and you only notice it when it fails.

Wi-Fi, internet security, connection troubleshooting, and networking for small businesses. All written in-house.
Security
How to See Who Is Using Your Wi-Fi
A router's device list rarely names anyone. What appears instead is a row of names you don't recognise, most of which are your own.
Troubleshooting
How to Change DNS on Your Phone, Laptop, and Router
Changing it on the router covers the whole house at once. Changing it on a device helps precisely when you're away from home.
Security
WPA2 vs WPA3 and Which One to Use
WPA3 closes the one weakness that gets exploited most. But switching to it outright can stop some of your devices connecting at all.
Networking
How to Limit Wi-Fi Speed per Device
Throttling rarely fixes the actual problem. What makes a network feel slow is usually not whoever is downloading the most.
For Business
How to Create a Wi-Fi QR Code for Guests
One code on the table ends the "what's the password" conversation for good. What rarely gets considered: that code can also be photographed and taken home.
Hardware
How to Set Up a New Router from Scratch
The leaflet in the box walks you as far as the internet coming on, then stops. It is the settings after that point which decide the year ahead.
Regulation
Using a Neighbour's Wi-Fi Without Permission
The signal reaches your house, so it feels like nothing is being taken. The law looks at it from an entirely different angle.
Networking
Should You Enable IPv6 on Your Router?
IPv6 doesn't make the internet faster. What it solves is running out of addresses, and that affects something you may be experiencing without realising it.
Hardware
How to Choose a USB Wi-Fi Adapter for a PC
A 1200 Mbps adapter plugged into a USB 2.0 port will never exceed around 300 Mbps. The port is the bottleneck, not the adapter.
For Business
Choosing a Wi-Fi Installation Service for Your Business
A quote made without seeing the site almost always misses. One question upfront is enough to separate the serious from those merely selling hardware.
Troubleshooting
How to Fix DNS Server Not Responding
This message comes from the Windows diagnostic tool, and it often misleads. Half the time it is not about DNS at all.
