If you’re using a modem, make sure the modem is turned on and set up according to your internet service provider’s (ISP) instructions.
Plug an Ethernet cable that’s connected to your network into your computer’s Ethernet port
. (The network connection may be through a device such as a modem, router, or switch, or a wall jack.)If your computer doesn’t have an Ethernet port, you can use a USB to Ethernet Adapter or a Thunderbolt to Gigabit Ethernet Adapter.
