A VPN (Virtual Private Network) creates a secure, encrypted tunnel between your device and the internet. Instead of connecting directly to websites or services, your traffic travels through the VPN server first. This masks your real IP address and shields your data from prying eyes. How a VPN Works Connection: You launch a VPN app…
Start by listing your office requirements. How many users will connect? What applications do they need—email, file sharing, VoIP, or video conferencing? Do you need guest Wi-Fi? Identifying bandwidth demands and device types (desktops, laptops, printers, IP phones) guides your network design and hardware choices. Choose the Right Hardware A small office network typically requires…
A mesh network uses multiple devices—called nodes—to spread Wi-Fi evenly across your space. Unlike a single router setup, mesh nodes work together. One node connects to your modem, and the others relay the signal, creating a seamless network with a single name (SSID). How Mesh Networks Work When you move around, your device automatically switches…
Network latency is the time it takes for a data packet to travel from its source to its destination and back again. In simpler terms, it’s the delay you experience whenever you send or receive information over a network. Latency is typically measured in milliseconds (ms). Lower latency means snappier responses; higher latency can make…
A firewall acts like a gatekeeper between your internal network and the internet. It filters incoming and outgoing traffic based on rules you set. By blocking unauthorized connections and allowing safe data through, a firewall helps prevent hackers, malware, and other threats from reaching your devices. How Firewalls Work Firewalls inspect data packets—the small chunks…

The right tool lets you view device status, track bandwidth, and receive alerts—without a steep learning curve. 1. PRTG Network Monitor (Free Version) Overview PRTG by Paessler…
A Local Area Network (LAN) connects devices within a limited space—like a home, office, or school. It lets computers, printers, phones, and smart devices share files, printers, and internet access at high speeds. LAN Key Characteristics Coverage: Usually a single building or floor (tens to hundreds of meters) Speed: Fast connections, often 100 Mbps to…
Network protocols are like the rules of the road for computers. They define how devices talk, share information, and understand each other over a network. Without these agreed-upon rules, your web browser, email app, and streaming service couldn’t work together. Think of protocols as languages and traffic signs that keep data moving smoothly and safely…
An unsecured Wi-Fi network is an open door. Neighbors, passersby or hackers could use your bandwidth, steal personal information, or launch attacks on your devices. A few easy steps can lock down your home network and give you peace of mind. 1. Change the Default Admin Credentials Most routers come with a default username and…
