Connect your Mac to the internet using Ethernet
You can use Ethernet to connect to the internet, either through an Ethernet network or through a DSL or cable modem. If you’re using a modem, make sure the modem is turned on and connected to the wall jack with the cable that came with the modem.
Use an Ethernet cable to connect your computer’s Ethernet port to a modem or other network device (for example, a switch or a router). If your computer doesn’t have an Ethernet port, try using a USB to Ethernet adapter, or a Thunderbolt to Gigabit Ethernet adapter.
In many cases, you’ll automatically connect to the internet. If not, complete the following steps to enter your network settings. If you aren’t sure what to enter, check with your network administrator or ISP.
On your Mac, choose Apple menu
.Select Ethernet in the list on the left.
Click the Configure IPv4 pop-up menu, then choose your ISP’s recommended configuration method.
Using DHCP: Choose this if you receive an IP address automatically from your ISP.
Using DHCP with manual address: Choose this if you received a specific IP address and your ISP uses DHCP, then enter the IP address.
Using BootP: Choose this if your ISP uses BootP.
Manually: Choose this if you received a specific IP address, a subnet mask, and a router address from your ISP, then enter those values.
If you received additional settings, such as an IPv6 address or a DNS server address, click Advanced, enter the settings, then click OK.
Click Apply.
