IP address conflict troubleshooting

An explanation of the possible causes of issues related to IP address conflicts, and potential solutions.

Troubleshooting IP addressesIP address conflict

Under normal circumstances, the display designated as the Datamaster or a YachtSense Link router in a Raymarine system will act as a DHCP server, and assign unique IP addresses to all connected network devices during power up. However, under certain circumstances, an IP address conflict can occur when more than one device on the network has been assigned the same IP address. Possible causes and solutions for this are shown below.

Possible causes

Possible solutions

There is more than one device on the network acting as a DHCP server:

  • Disable the DHCP server on devices where it is not required.

  • Where multiple DHCP servers are required, ensure that there is no overlap in the IP address ranges that the servers are assigning.

One or more devices have been assigned a static IP address:

  • Change devices with a static IP address to Dynamic, to ensure that a unique address is assigned to each device, via DHCP.

  • If a static address is required, ensure that it is outside of the range of addresses which can be assigned by the DHCP server.

YachtSense Link router software update:

From router software version v4.20 or later, displays can no longer be connected to the router using a Wi-Fi connection.

  • If your display has previously been connected using a Wi-Fi connection but also has a RayNet wired connection, then you will need to ‘Forget’ the Wi-Fi network connection, and use the RayNet wired connection instead.
