# If you’re trying to use Safari while offline

Your Mac must be connected to the Internet to go to a webpage using Safari, unless you added the page to your Reading List while you were online.

- Your Mac may be temporarily disconnected from the Internet because you moved it somewhere that doesn’t have a Wi-Fi network, or the Wi-Fi network isn’t working. Try again when your Mac is in a location that you know has a working Wi-Fi network.

- You may not be able to connect to the Internet because of a problem with your router or modem, or an outage with your Internet service provider (ISP). To help solve Internet connection issues, use Network Diagnostics.
