Please try the following steps:

• If you're using an Intel-based MacBook or Windows laptop, update the Ethernet driver from the Realtek website.

• Test the dock using another laptop to check if the issue persists.

• If possible, connect the Ethernet cable directly to your laptop's Ethernet port to verify a stable connection.

• Try using a different Ethernet cable.

• Test with a different router or network.

• Unplug the dock from your laptop and disconnect all connected devices. Wait at least 5 minutes. Then, restart your laptop and reconnect the dock.
