Router
A device that routes network traffic between your local devices and the internet.
What a router is
A router is a networking device that manages traffic between your local home network and the internet. When multiple devices in your home need to go online at the same time, the router determines how to direct traffic to and from each one. It also manages your home's Wi-Fi network, assigning addresses to devices and routing data packets to the right destination.
The router works alongside your modem. The modem connects your home to your ISP. The router takes that single internet connection and shares it with all your devices, whether they connect over Wi-Fi or a wired Ethernet cable. Many home ISPs provide a combined gateway device that handles both functions.
Routers vary widely in capability. Basic models handle a few devices over moderate distances. High-end routers support Wi-Fi 6 or Wi-Fi 6E, handle dozens of simultaneous devices, and cover large homes with strong signal. The right router depends on your home size, the number of connected devices, and the speed of your internet plan.
Why your router matters for your connection
Your router is often the biggest factor affecting the speed and reliability of your Wi-Fi. Even a gigabit fiber connection will feel slow if your router cannot distribute it effectively. An old router may cap your Wi-Fi at speeds far below what your plan delivers. It may also struggle to serve many devices simultaneously without slowing down.
Router placement is also critical. Walls, floors, and large appliances all reduce Wi-Fi signal strength. Placing the router centrally and at an elevated position helps the signal reach all corners of your home. A router tucked in a closet or behind a TV cabinet wastes much of its potential.
Router at a glance
| Wi-Fi Standard | Max Speed | Best For |
|---|---|---|
| Wi-Fi 4 (802.11n) | Up to 600 Mbps | Basic use, older devices |
| Wi-Fi 5 (802.11ac) | Up to 3.5 Gbps | Most modern households |
| Wi-Fi 6 (802.11ax) | Up to 9.6 Gbps | Dense device environments |
| Wi-Fi 6E | Up to 9.6 Gbps + 6 GHz band | Less interference, new devices |
Common questions about routers
Every 3-5 years is a reasonable guideline. Router hardware ages and firmware support eventually ends. If your router no longer receives security updates or cannot support current Wi-Fi standards, it is time to upgrade.
A traditional router broadcasts Wi-Fi from a single point. A mesh system uses multiple nodes placed around your home, each acting as a router that communicates with the others. Mesh systems provide more even coverage in large homes or buildings with thick walls.
Yes. An old or underpowered router can bottleneck your connection. If your speed test over Ethernet is fast but Wi-Fi is slow, the router is the likely cause. Running a speed test directly from a device wired to the router helps isolate whether the problem is the router or the ISP connection.
