1. Check wiring and connections

Step 1: Check if the LED light on the docking station is on.

Step 2: Replug the cables connected to the docking station: 

1. The USB-C cable between the dock and Mac 

2. The DC power cable

Step 3: Replug the Ethernet cable into the dock’s network port. Normally, you should see a steady green light and a flashing orange light.

*If the lights are abnormal or not showing, try using another device to confirm whether the network connector is functioning properly.

Step 4: Use your phone’s flashlight to check the RJ45 port on the dock for any damaged or bent pins.

*If pins are bent or pushed down, carefully correct them with a toothpick or fine tool. 

*If the port is damaged and causes loose Ethernet connections, you can temporarily secure it with tape, or contact iVANKY support for replacement.

Step 5: Make sure macOS and all software are updated to the latest version.

Step 6: Update the Mac ethernet driver. For details, please visit the iVANKY official guide: https://ivanky.com/blogs/news/ivanky-ethernet-driver-download-guide

Step 7: Go to the Apple menu (upper-left corner) > System Settings> click Network. You should see USB 10/100/1000 LAN and USB 10/100/1G/2.5G LAN.

*Check the indicator color below each option and follow the corresponding troubleshooting steps.

*If the network is not recognized, please follow the steps for a gray indicator (no network detected). 

2. Yellow status indicator below the service name (self-assigned IP)

Step 1: Restart the computer to reassign the IP address.

Step 2: Connect the network cable directly to another device (for example, a desktop computer or a laptop with an Ethernet port) to check whether the cable works properly.

Step 3: Turn off the modem or router and wait for 5 minutes. Then turn it back on to reassign the IP address.

Step 4: Re-plug the network cable to reassign the IP address.

Step 5: Reset the router to reassign the IP address.

3. Grey status indicator below the service name (no recognition of network access)

Step 1: Connect the network cable directly to another device (such as a desktop computer or a laptop with an Ethernet port) to test whether the cable is working properly.

Step 2: Create a new Apple sub-account.-> Restart the computer and log in with the sub-account.->Test whether the issue is caused by a software conflict on the main account.

4. Green status indicator (connected but not working)

Step 1: Reconnect the Ethernet cable.

Step 2: Plug the Ethernet cable directly into another device (e.g., a desktop PC or a laptop with an Ethernet port) to check if the cable works properly.

Step 3: If possible, try using a different Ethernet cable.

If the issue persists after these steps, please contact the iVANKY support team and provide the following information so we can check for possible device compatibility issues:

1.Your macOS version

2.Which device is not working and its model

3. A purchase link if available 

1. Check accessories and connections

Step 1: Restart your Mac and make sure both ends of the dock’s USB-C cable and the Ethernet cable are securely connected.

Step 2: Reconnect the accessories between your Mac and the monitor. You can try flipping the dock’s USB-C connection to the Mac, and re-plug the Ethernet cable into the dock.

Step 3: Connect your Mac directly to the network using Ethernet or Wi-Fi to check whether the internet speed returns to normal.

Step 4: Disconnect all other devices from the dock except the Ethernet cable. Also, unplug other devices from the router, keeping only the cable connected to the dock. If the issue persists, try using a different WAN/LAN port on the router.

Step 5: Confirm with your cable provider that the Ethernet cable supports gigabit speeds (≥800 MB/s). You can also test the cable by connecting it directly to another device to verify whether it meets gigabit performance. Replace the cable if it cannot.

2. Restart the router

Step 1: Unplug the router and Ethernet cable, then wait at least 30 seconds.

Step 2: Reconnect the Ethernet cable to the router.

Step 3: Once the Internet indicator light is on (normally the green light stays solid and the orange light blinks), check if your Mac can access the Internet.

3. Update software

Step 1: Make sure macOS and all software are updated to the latest version.

1. To prevent unresponsive wake-up issues, please use a USB-C to USB-C or HDMI to HDMI cable.

2. If the dock does not wake up automatically, try unplugging and reconnecting the dual USB-C cables.

3. Avoid using LG 27MD5KL 5K monitors or Samsung ViewFinity S9 5K monitors, as they may cause compatibility issues when connected with other displays. We recommend using Apple displays.

4. To connect two 6K@60Hz displays, both monitors must be Apple’s 6K display (Pro Display XDR model).

5. If display issues occur when using a third-party USB-C to HDMI cable, please try the included USB-C to HDMI cable or contact iVANKY Support for recommended alternatives.

6. The optical audio port does not support system-level volume control. Please adjust the volume through your speakers. If you prefer to adjust volume from your computer, use the 3.5 mm audio port instead. 

Q1. Why can I hear the fan spinning?

1. The device uses a unique fan design to maintain stability under high-power, full-load conditions.

2. Because of the strong performance, the fan helps reduce the device’s temperature and ensures smooth operation.

3. When the device is idle, disconnect it from the computer and the fan will stop spinning.

Q2: What to do if the docking station stops working or works intermittently?

1. Press the power button and check if the LED indicator is on. If the dock is powered on, disconnect it from your laptop and all connected devices. Wait at least 5 minutes, then restart your laptop and reconnect the dock.
