Router
A device that directs internet traffic to multiple devices in a home or business.What is a Router?
A router is a device that directs internet traffic between your modem and the devices in your home or office. It allows multiple devices — like phones, laptops, and smart TVs — to connect to the internet wirelessly or via Ethernet cables.
How Routers Work
When your modem brings internet into your home, the router distributes that connection to your devices. It assigns local IP addresses, manages traffic, and can prioritize certain applications or devices depending on settings.
Router vs Modem
| Feature | Router | Modem |
|---|---|---|
| Role | Shares internet with devices | Connects to ISP’s internet service |
| Connection | Wi-Fi and Ethernet | Coaxial, DSL, or fiber line |
| Required For | Wireless networking | Internet access |
| Combined? | Sometimes built into one device | Often part of a gateway device |
Types of Routers
- Standalone Routers: Traditional home routers for basic wireless networks
- Mesh Routers: Use multiple nodes for whole-home coverage
- Gaming Routers: Prioritize low latency and high bandwidth for online gaming
- Business Routers: Offer VPN support, firewalls, and more advanced features
- All-in-One Gateways: Combine modem and router in one device (common with ISPs)
Choosing the Right Router
When choosing a router, consider:
- Speed capabilities: Match it to your internet plan
- Wi-Fi standard: Preferably Wi-Fi 6 or newer
- Home size and layout: Mesh systems for large or multi-floor homes
- Device load: Higher-end routers for homes with many connected devices
- Security features: Look for parental controls, guest networks, and automatic updates
FAQs
Do I need a router and a modem?
Yes, unless you use a combo device. The modem connects to the internet, and the router shares that connection with your devices.
How often should I replace my router?
Every 3–5 years, or sooner if you upgrade your internet speed or experience connection drops.
Can I use any router with any internet provider?
Generally yes, but always check compatibility — especially with fiber or DSL connections, which may have specific requirements.
What is a dual-band router?
A dual-band router broadcasts on two frequencies — 2.4 GHz for range and 5 GHz for speed — offering more flexibility and performance
How do I know if my router is slowing down my internet?
Run a speed test near your modem. If the speed is significantly lower over Wi-Fi or far from the router, it may be time for an upgrade.
