Your Starlink Ethernet Adapter is connected, but your wired device has no internet. The adapter isn't the only thing to check: the cable, connected device, router, and Starlink service all need testing. Start with your hardware setup, then narrow down the fault before resetting anything or buying a replacement.
Make sure your setup needs the adapter
The separate Ethernet Adapter is for the Gen 2 router, which ships with Standard Actuated and High Performance kits and has no built-in Ethernet ports. Keep that router connected, including when attaching a third-party router.
Router 3 has two LAN ports beneath its rear rubber cover; Router Mini has one and requires Cat5e or better cabling. Connect wired devices to those ports. Adding Router 3 to Standard Actuated hardware keeps the Gen 2 router in place, because Router 3 can't be the main router on that kit. But the documented setup pairs it wirelessly as a mesh node: put it in clear line of sight of the Gen 2 router, plug it into power, then select PAIR when the app shows PAIR NEW MESH NODE. Its two LAN ports then carry your wired devices without the Gen 2 Ethernet Adapter. You only need the adapter for a wired mesh link between the Gen 2 router and Router 3.
The Starlink Mini dish is different from Router Mini: it has an integrated router and its own Ethernet port. Remove the port plug and connect the Mini Ethernet cable or an ordinary RJ45 cable between that port and your wired equipment. Use the official sealing cable where weatherproofing matters, because an ordinary RJ45 connection does not preserve the specified IP67 rating.
For Enterprise and Performance Gen 1/Gen 2 kits with external power supplies, connect the power supply's Ethernet output or supplied Ethernet cable directly to your third-party router's WAN port. These kits don't need the Standard Actuated adapter-and-router arrangement.
If Wi-Fi also fails, check the Starlink connection
Use this check to separate an Ethernet fault from a wider service problem. Starlink Wi-Fi must be available, which means bypass mode must be off.
Test internet access on a phone or another device connected to Starlink Wi-Fi. If Wi-Fi works, continue with the Ethernet checks below.
Open the Starlink app to review its alerts.
If a cloud icon appears beside the network name, select that name and choose Local.
Address the displayed service, power, cable, or obstruction problem first if Wi-Fi also fails. Replacing the Ethernet Adapter won't resolve those underlying problems.
For outages at scheduled times, connect your phone locally to Starlink. Sleep periods stop both internet service and remote management.
Open Settings > Starlink > Sleep Schedule.
Turn off Enable sleep schedule.
Select Save.
Reseat the Gen 2 adapter and restart the router
This fixes loose connections and incorrect Gen 2 adapter wiring.
Disconnect Starlink from electricity before changing connections.
Inspect the dish cable, adapter connectors, and pins for damage, bends, or loose seating. Damaged components need replacement through support.
Connect the dish cable securely to the Ethernet Adapter.
Connect the adapter's attached cable securely to the Gen 2 router.
Plug the Ethernet cable from your wired equipment into the adapter's RJ45 socket.
With electricity still disconnected, disconnect both ends of the power cable.
Wait at least 10 seconds.
Reconnect the power cable to restore power.
Check the Starlink app after the router restarts.
Test another outlet if the router still shows no power.
Narrow down the fault with another cable and device
These tests narrow down what needs attention before you spend money on hardware.
- 1.Test a known-working Ethernet cable between the adapter or built-in LAN port and your device. If the connection works, replace the original cable.
- 2.Connect a different computer or Ethernet device using that cable. If only the original device fails, focus on its Ethernet interface; failure across multiple devices points toward the Starlink adapter or router.
- 3.Try another suitable Ethernet port if your hardware has one. Router 3 has two LAN ports.
- 4.Remove third-party routers, switches, or mesh equipment and test a device directly with Starlink equipment. If Starlink is in bypass mode, first restore normal router operation using the reset instructions below. If the interruptions stop, investigate the equipment you removed.
Correct the settings on a third-party router
Connect the cable from the Starlink adapter or native Ethernet output to your third-party router's WAN port.
Configure that router's WAN interface to obtain its address automatically through DHCP. Menu names depend on the manufacturer.
On an ASUS router using ASUSWRT, open http://www.asusrouter.com or the router's LAN address in a browser.
Sign in to the router.
Select WAN > Internet Connection.
Set WAN connection type to Automatic IP.
Select Apply. ASUSWRT labels vary by firmware.
To hand routing to the connected third-party router, open Settings in the Starlink app.
Enable Bypass Mode. On Router Mini, use Settings > Bypass Mode > Enable. This disables Starlink Wi-Fi; leaving bypass mode requires a factory reset.
If your router's WAN health checks incorrectly report Starlink as offline, set their ping target to 8.8.8.8 or 1.1.1.1. Starlink's DNS servers do not answer ping; the health-check menu names depend on your router.
Set the check interval to 10 seconds, as Starlink recommends.
Set the failure threshold to five consecutive unsuccessful checks.
Tip: You don't need bypass mode just to connect an ordinary wired device.
A factory reset and the point to contact support
After the cable and device tests, use only the reset method matching your setup, then retest; a factory reset erases network settings.
For an associated router outside bypass mode, connect to Starlink Wi-Fi.
Open Settings > Router > Factory Reset.
Move the confirmation slider. Offline or unassociated routers display manual instructions instead; app reset is unavailable in bypass mode.
For a Gen 2 physical reset, including to exit bypass mode, unplug and reconnect power six times, approximately two to three seconds apart. Use six cycles, not three.
Wait for reboot.
Join STARLINK.
Set your network credentials under Settings > Router.
Select Save.
Reset associated mesh nodes afterward.
For Router 3 or Router Mini, briefly press the reset button with a paper clip. Router 3's button is beneath its rear LAN-port cover; Router Mini's is on its back.
Wait for reboot.
Configure the network again.
For the Starlink Mini dish, press the rear reset control firmly until it clicks and hold it for three seconds. The indicator flashes rapidly and goes out as the unit resets.
After resetting and configuring your router, retest Ethernet with the known-working cable and a second wired device.
If Ethernet still fails, open Starlink's Ethernet troubleshooting page in the app or Help Center.
Select Contact Support.
Include photographs of the adapter, connectors, ports, and any damage, plus the cable and device tests you completed.
Have support diagnose both the adapter and router before ordering a replacement: replacing the adapter alone does not guarantee a working connection.
Frequently Asked Questions
Does the Starlink Ethernet Adapter need a driver update?
Starlink software updates download automatically and install during a reboot. There is no separate Ethernet Adapter driver update in that process. To choose an installation window on systems offering the setting, open Settings > Starlink > Software Updates and select Overnight, Morning, Afternoon, or Evening.
What should I try if only my Mac cannot connect over Ethernet?
If other wired devices work and your Mac uses DHCP, renew its lease. Open the Apple menu > System Settings > Network and select your Ethernet service. Choose Details > TCP/IP > Renew DHCP Lease > OK.
What if Ethernet works on other devices but not my Windows 11 PC?
Open Microsoft's Ethernet troubleshooting page and select Run the troubleshooter in Get Help. Follow its prompts. As a last resort, open Settings > Network & internet > Advanced network settings > Network reset > Reset now > Yes, then restart. Check your VPN software and virtual switches afterward and reconfigure them if needed.
Where can I buy a replacement Starlink Ethernet Adapter?
Sign in to the Starlink Shop and locate the Ethernet Adapter compatible with your kit. Confirm the model before ordering, and check availability and pricing in the signed-in shop.
