Check your cables.

One of the most common problems with home networks is that a cable is loose or unplugged somewhere. Check to make sure everything is hooked up properly.

Check a different website.

If you can't connect to a particular website, try a few others to see if any of them load. If one website loads and another doesn't, the problem is probably with that website and not your network.

Try resetting your devices.

You could try "power cycling" your devices, which means rebooting all of the pieces of your network one at a time.

To power cycle your network:

• Unplug your modem for at least 10 seconds; plug it back in
• Unplug your router for at least 10 seconds; plug it back in
• The lights on your router should start blinking
• When the light comes on that shows you have an Internet connection, reboot your device
• Establish a wireless connection between the device and your network
