You know your router is connected to your modem by checking the LED lights (especially the WAN/Internet light on the router, which should be solid or blinking) and the physical cable connection between the modem's LAN port and the router's WAN/Internet port; if lights are solid (not red/orange) and devices can get online, the connection is working.
Checking Your Network's Connection
Today's technology has evolved so that we now have what is called a gateway. The gateway combines the function of both the modem and the router into one handy device. That way there's only one device to plug in and configure.
Understanding the LED lights on your equipment
The router connects to your modem and then to your devices (laptops, smart TVs, printers, etc.) via either an Ethernet cable or a wireless connection, commonly referred to as WiFi. The router creates a local area network (LAN) within your house, allowing your devices to share files and peripherals like printers.
Unplug the power cord from the WiFi router. Wait at least one minute, then reinsert any batteries and reconnect power to the modem. Then wait at least two additional minutes to allow the modem to power on. The modem's lights should gradually turn on, confirming the device has power and is connected to the internet.

A green light means the connection was successful and the WiFi connection is Online. A yellow light means the interface initialized but is disabled because it is not in use. A red light means the connection failed and the WiFi connection is Offline.

While the modem provides the internet connection, the router is responsible for managing and directing the traffic within your local network. It serves as a central hub for all the devices connected to your home network, ensuring they can communicate with each other and access the internet simultaneously.
Your router faces inwards—it connects multiple computers in one network together. It creates a local area network (LAN), which is what you would call your internal network of computers in your office or home. Your modem faces outwards—it's what connects your LAN to the outside world, the Internet.
Experts recommend replacing your router at least every five years—and every two to three years for those of you who use several high-bandwidth devices and smart home devices.
Typically by unplugging the power cord, waiting 20-30 seconds and plugging it back in. If you hit the small RESET button on the back of the router as pictured below, or something like it that may even be recessed, it will do a Factory Reset of that router.
Common causes include modem or router problems, ISP outages, slow speeds, network congestion, weak Wi-Fi signals, or IP address conflicts. Restarting your router or modem can clear temporary glitches. It also fixes IP issues and helps restore a fresh internet connection.
No, they are not the same thing. Wi-Fi is simply a means of wirelessly connecting a device to the internet. The internet is a global network you can access to find or share information and communicate with people.
Your modem should ideally have a solid green or white Power light, a solid green Internet/WAN light (or blinking green during connection), and blinking green LAN/Ethernet lights for connected devices; blinking Wi-Fi lights indicate activity, while a solid one means Wi-Fi is on. A solid green or blue means everything's working, while red/orange or off usually signals connection issues, requiring a restart or ISP contact.
Power Light
Blinking green/white: It happens when the router is starting up or updating firmware. Give it a few minutes to finish. Red or off: There might be a power issue. Check the cable or power source; it may indicate a hardware fault.
Routers wear out over time due to constant use, dust buildup, and outdated technology. To check if the router is the issue, use an internet speed test tool like Ookla Speedtest or Fast.com. Test your speeds while connecting a laptop or wireless device, like your phone, to your router or home network.
Slow and Steady Blinking: If a light is blinking slowly, your modem or router is trying to connect. This often happens when the device is starting up or trying to talk to your internet provider. Rapid Blinking: Fast blinking usually means your device is working and sending or receiving data.
Connecting via Ethernet Cable (Non Wi-Fi setup)
The simplest method is to connect a computer to the modem or gateway device supplied by your Internet service provider (ISP). If your computer detects an Internet connection, you're ready to set up the router.
A modem brings the internet into your home by translating signals from your ISP, while a router shares that connection with multiple devices via Wi-Fi or Ethernet, acting as a traffic controller for your local network; you need both for a full setup, but many devices today combine both functions into one "modem-router" (or gateway).
