To submit feedback regarding this tutorial, please log onto www.lantronix.com/support
and submit
a technical support e-mail.
All IP addresses and subnet masks used in this tutorial are examples. To obtain an IP address to
assign to your device, please contact your network administrator.
Subnets
If DeviceInstaller reported a subnet issue with your PC, it is because the PC’s IP address and the
IP address you are trying to assign to your Lantronix device are on different subnets. The IP
addresses of the device and the PC running DeviceInstaller must be on the same Local Area
Network and subnet.
For DeviceInstaller to assign an IP address to your Lantronix device successfully:
• Your PC’s IP address and the address you want to assign to your Lantronix device must
be on the same subnet.
• No routers or gateways can exist between your PC and your Lantronix device.
DeviceInstaller does not support assigning an IP address across a router or gateway.
