A router directs internet traffic, while a repeater extends a Wi-Fi network's range. Let's explore the key differences:
Router: The Internet's Traffic Director
A router is the central hub of your network. It receives internet data from your Internet Service Provider (ISP) and distributes it to all your connected devices. Think of it as a post office for your internet data, sorting and sending information to the right place.
- Key functions: Connects your home network to the internet, assigns IP addresses, manages network traffic, and creates a firewall for security.
- Example: Your modem connects to your router, which then connects your laptop, phone, and smart TV to both the internet and each other.
Repeater: Extending Wi-Fi Reach
A repeater, also known as a Wi-Fi extender or booster, doesn't connect to the internet directly. Instead, it receives your existing Wi-Fi signal from your router and retransmits it, increasing the signal's range. Imagine it as a megaphone for your Wi-Fi signal.
- Key function: Extends the coverage area of an existing Wi-Fi network. It does not create a new network, simply boosts the existing one.
- Example: If your router's signal doesn't reach your backyard, a repeater placed in between can strengthen the signal allowing you to use Wi-Fi there.
Summarizing the Key Differences
| Feature | Router | Repeater |
|---|---|---|
| Primary Function | Connects to internet, routes traffic | Extends Wi-Fi range |
| Internet Connection | Direct connection to ISP | No direct internet connection |
| Network Creation | Creates a new network (with its own SSID) | Doesn't create a new network (usually same SSID) |
| Functionality | More complex, offers advanced features | Simpler, limited functionality |
As noted in the provided references, a repeater has very limited functionality compared to a router. A router handles internet connection, IP address assignment, and network traffic management, while a repeater only repeats the existing Wi-Fi signal. One key difference mentioned is that a repeater typically uses the same SSID (network name) as the main router, while a router creates its own separate network. Several references highlight the use of the terms "extender" and "booster" as synonyms for repeater.
