- Check all display cables (DisplayPort, Thunderbolt 3) are securely connected to both the docking station and the monitor.
- Ensure your monitor is set to the correct input source.
- Verify your computer's display settings are configured for extended or mirrored displays.
- If using a MacBook with an M1 chip, remember it supports only one external monitor.
- Try connecting the monitor directly to your computer to rule out monitor or cable issues.
- SSD Not Detected:
- Ensure the M.2 SSD is correctly installed and secured in its bay.
- Check if the SSD is properly initialized and formatted in your operating system's Disk Management (Windows) or Disk Utility (Mac).
- Verify the SSD type (NVMe or SATA) is compatible with the enclosure.
- Slow Data Transfer:
- Ensure you are using a Thunderbolt 3 compatible port on your host computer and a 40Gbps Thunderbolt 3 cable.
- Check that the connected USB devices are capable of the advertised speeds (e.g., 10Gbps devices on 10Gbps ports).
- External factors like other connected devices or system load can affect transfer speeds.
- Network Issues (Ethernet):
- Verify the Ethernet cable is securely connected to both the docking station and your router/modem.
- Check your computer's network settings.
- Ensure your router/modem is functioning correctly.
