Time to get more information so the hive mind can ponder the situation:

- Photo of the machine display showing the laser’s IP address
- [Screenshot](https://www.take-a-screenshot.org/) of the [LightBurn `Device Settings`](https://docs.lightburnsoftware.com/2.0/Reference/DeviceSettings/BasicSettings/) showing the laser’s IP address
- [Screenshot](https://www.take-a-screenshot.org/) of the [Windows `ipconfig`](https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/ipconfig) results
- Does the machine controller’s display show the network is connected?
- [Screenshot](https://www.take-a-screenshot.org/) of the [Windows `ping`](https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/ping) of the laser’s IP address from the PC
- With the laser turned **off** , [screenshot](https://www.take-a-screenshot.org/) of the [Windows `ping`](https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/ping) when you [ping](https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/ping) the laser’s IP address

Type those commands in a [`Command Prompt` window](https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/windows-commands) that you start by [hitting the `Win` key and the `R` key](https://support.microsoft.com/en-us/windows/keyboard-shortcuts-in-windows-dcc61a57-8ff0-cffe-9796-cb9706c75eec#windowskey), then typing `cmd` into the `run` dialog box.
