Ethernet Port is Not Working on FRC roboRIO

Issue Details

• I cannot connect to the device.
• The Ethernet status lights do not turn on. 
• The Ethernet status light blinks intermittently, but the device is not assigned an IP address.
• The lights on the Ethernet port remain solid even when unplugged. 

Solution

Go through the following troubleshooting steps:

• Ensure that you can connect to the device via USB. If not, this may indicate a larger connection issue. 
• Try using a known-working Ethernet cable.
• Try connecting a different roboRIO to the computer to see if the connection issue persists. 
  • If other roboRIOs can connect over Ethernet to this computer, check to see if the software images and firmware versions match with the non-working roboRIO. If not, reimage and update the firmware to match the working roboRIO. 
• Try connecting to the roboRIO on another computer.
  • If this is successful, there may be an issue with the original computer's networking or software.
• Try connecting to a different, known-working network connection (i.e. another wall port or another port on the router you are using.)
• To eliminate any potential software issues, reimage the device from safe mode.
