Configure wired network connections
Ethernet settings manage wired network connections through built-in Ethernet ports or USB and Thunderbolt adapters, including IP configuration, DNS, and connection priority relative to Wi-Fi.
How to open Ethernet
- Open System Settings → Network
- Select the Ethernet service from the sidebar
- Configure IP settings under Details, choosing DHCP or Manual
- Reorder services via the three-dot menu → Set Service Order if needed
What you should know
- Automatic or manual IP address configuration (DHCP, BootP, or manual)
- Custom DNS server and search domain entry
- Service order controls whether Ethernet or Wi-Fi takes priority when both are connected
- Support for multiple Ethernet adapters shown as separate services
Why it matters
A wired Ethernet connection typically offers more consistent latency and throughput than Wi-Fi, which matters for tasks like large file transfers, video conferencing, or working with network-attached storage. Correctly configuring Ethernet, including its priority relative to Wi-Fi, ensures the Mac actually uses the faster, more reliable connection instead of silently falling back to wireless.
Best practices
- Set Ethernet above Wi-Fi in Network service order if you want it prioritized automatically
- Use DHCP unless your network administrator has specifically provided static IP details
- Label multiple Ethernet adapters descriptively if you regularly switch between networks
- Verify a solid link light on the adapter or port if a wired connection is not showing as active
Common problems and fixes
- Mac still uses Wi-Fi even with Ethernet connected
- Reorder network services in Network settings' three-dot menu so Ethernet is listed above Wi-Fi.
- Ethernet adapter is not detected
- Confirm the adapter is compatible with your Mac's port type and try a different cable or port to rule out a hardware fault.
- No internet access despite an active Ethernet link
- Check DNS and IP configuration, and try renewing the DHCP lease from the Ethernet service's TCP/IP settings.
Tips and tricks
- Use a Thunderbolt to 10GbE adapter for high-throughput tasks like editing video off network storage.
- Check the small colored status dot next to each network service in settings to quickly see which connections are active.
Frequently asked questions
Do all Macs have a built-in Ethernet port?
No, many current Mac laptops require a USB-C or Thunderbolt to Ethernet adapter since they lack a built-in port.
Can I use Ethernet and Wi-Fi at the same time?
Yes, both can be active simultaneously, with the service order determining which is preferred for outgoing traffic.
Is Ethernet faster than Wi-Fi?
Typically yes for consistency and latency, though maximum speed depends on your specific router, adapter, and cabling.
