Conclusion
In conclusion, Macs do inherently prioritize Ethernet connections over Wi-Fi whenever both are available, taking advantage of the greater speed, stability, and lower latency that Ethernet provides. However, the flexibility in macOS allows users to customize their network settings based on personal needs and preferences.
Being aware of the advantages and limitations of both Ethernet and Wi-Fi helps users to make informed decisions for their specific circumstances. Whether you opt for the reliability of wired connections or the flexibility of wireless networking, understanding these technologies will enhance your overall computing experience. So the next time you connect your Mac, you’ll be better equipped to decide which connection—Ethernet or Wi-Fi—will serve you best.
1. Does a Mac prioritize Ethernet over Wi-Fi by default?
Yes, by default, a Mac typically prioritizes Ethernet over Wi-Fi when both connections are available. This means that if you have an Ethernet cable plugged into your Mac, it will use that connection for internet access instead of the Wi-Fi network. This preference is due to Ethernet generally providing a more stable and faster connection compared to Wi-Fi.
However, users can change these settings if they prefer to prioritize Wi-Fi. This can be done through the Network Preferences in macOS, where you can manage the order of network service preferences, giving users the flexibility to choose their preferred connection method.
2. How can I check the network services priority on my Mac?
To check the network services priority on your Mac, you can go to System Preferences and then click on Network. In the Network window, you will see a list of available network connections, such as Ethernet and Wi-Fi. At the bottom of this panel, there is an option called ‘Set Service Order’ that allows you to change the order of your preferred connections.
Simply click on the gear icon (or the three dots) and select ‘Set Service Order’ from the dropdown menu. From there, you can drag and drop the network services to reorder them according to your preferences. Once you finish arranging them as needed, click ‘OK’ to save the changes.
3. Can I still use Wi-Fi if my Mac is connected to Ethernet?
Yes, you can still use Wi-Fi even when your Mac is connected to Ethernet. However, if both connections are active, macOS will give priority to the Ethernet connection for internet traffic, essentially sidelining the Wi-Fi connection. This means that the Wi-Fi will be available for use, but it won’t be utilized for internet access unless the Ethernet connection becomes unavailable.
In case you want to use Wi-Fi exclusively, you can either disconnect the Ethernet cable or change the priority of the networks as mentioned earlier. Adjusting the network order allows your Wi-Fi network to take precedence over the Ethernet connection when both are available.
