3. Determine the Connection Type

Devices can be connected to a network in two ways: wired or wireless. In order to continue, we need to determine the type of connection your device has.

A wired connection is provided by an Ethernet cable. Most commonly, these are used by desktop computers and other equipment you don't move around often.

If your device is not connected to the router with a cable, then you are using a wireless connection.

4. Fix a Wired Connection

To fix a wired connection, it's important to make sure the cable connecting the two devices is plugged in properly, and, if necessary, to reset the connection settings of the PC.

Check the Ethernet Cable

  1. Make sure the Ethernet cable is connected securely to the side or rear of your Mac.
  2. Make sure the other end of the Ethernet cable is connected securely to your Router, Modem or Wireless Gateway.

5. Fix a WiFi Connection

To fix a WiFi connection, it's important to make sure the PC is within good range of the wireless access point, and, if necessary, to delete the WiFi connection to that access point from within the network settings of the PC then reconnect the PC to the same WiFi network. A wireless access point can be anything between a wireless gateway, router, range extender (also called repeater or booster) or even mesh WiFi node.

Make Sure the PC is in Range

The PC needs to be within a reasonable range of the wireless access point in order to connect and have the best connection speeds.

  • In general, in most homes, you can be up to 30 feet from the access point for a decent connection.
  • From 30' to 50' away, the speeds will be slower, and may drop occasionally, but it should be usable.
  • Greater than 50' away, and the signal will most likely be too weak to overcome interference. The speeds will be slow, and the connection may be sporadic.

The above numbers are approximates only. Optimal range may vary based on access point type, make and model.

6. Check the Cables to the Modem and Router

Whether you have a wired or wireless connection, your Internet equipment such as your router, modem or wireless gateway requires to be wired to the Internet signal source and a power source.

Check the Connections to the Modem

  1. Make sure the power cable is connected firmly to the back of the modem and the electrical outlet, and the power light is on. The power light usually has the symbol below next to it.

  1. Make sure the connection to your service provider is proper. This could be a cable line if you have cable Internet, a phone line if you have DSL, or a Fiber cable for fiber Internet.

Check the Connections to the Router

If you have a "Wireless Gateway", or combination modem and router, you can skip these checks.

  1. Make sure the power cable is connected firmly to the back of the device and the wall, and the power light is on. The power light usually has the symbol below next to it.

  1. Make sure the Ethernet cable going to your modem is connected securely, and into the "Uplink" or "Internet" port.
  2. Make sure the other end of the Ethernet cable is connected securely to your Modem.

7. Restart the Modem and Router

Many times a connection issue can be resolved quickly and easily by restarting the Internet equipment:

  1. Disconnect the power cable from the back of your modem. The power cable is usually near the bottom, and tends to be a thin black cord. It usually does not have any clips on it.

  1. Some modems may have a battery backup to keep the telephone service working in case of a power outage. If the lights on your modem do not turn off when you disconnect the power cable, make sure you also remove the battery as well, then put it back in place before you reconnect the power cable.
  2. Disconnect the power cable from the back of your router, or if your router has one, push the power button to turn it off.
    Some Internet Service Providers now provide "Wireless Gateways", which contain both a modem and router in one simple device. Some users prefer separate devices. Both are perfectly acceptable. If you are using an all-in-one Wireless Gateway, you can safely continue without this step.

  1. Wait 30 seconds.
  2. Reconnect the power cables back into your modem and router.
  3. Make sure the power light comes on for each device. This is usually labeled by the symbol below.

  1. Please allow 3 to 6 minutes for the modem and router to start up fully.

8. Check the Internet Light on Modem and Router

There's a light representing the Internet connection. It will usually be labeled "Internet", or have one of the common symbols below.

Globe with meridians.
Lower case italic i.
Planet with satellite symbol.

Make sure the light next to this symbol is on and solid (or flickering very briefly) on both your modem and router. This means you should have a good connection to the Internet and your devices should be able to go online.
