Look at each connection point of your network setup. Check to see if each cable is plugged in securely by grasping the end of each cable and pushing inward. If your modem or router has a power button, make sure that it is in the On position.
Unplug each cable from your modem and router. Wait for three minutes, and then plug in your modem cables. Wait until each light is illuminated, and plug in your router cables. Test your connection by loading a website.
If your connection still isn't working, open your router or modem management screen by typing its IP address into a Web browser.

Download and install any updates to ensure that your system is working smoothly.
