No Connectivity on Ethernet port on RoboRio

[FRCSteve]

Our team has a RIO and cannot connect to it over the ethernet port.  USB connenctions work fine.

I get green (on solid) and Yellow (flickering) Lights when I connect the rio to a radio or switch however:

- I do not get a DHCP assigned IP address from either a FRC radio (Tried several radios that work with other RIOs), nor a COTS router. 

- When I try to configure a Static IP address using the Web interface, I still cannot ping the device IP, nor does it show up on a Network Scan from a driver station computer on the same network.

- Have tried using several "known good" Ethernet Cables.

- The Port and Pins look fine no foreign debris or damaged/bent pins that I can see.

I have tried to re-image and update the firmware, but that did not help.

Any way to restore the network connectivity to get connectivity to the radio working again?

Hi,

I am Thays from the technical support team.

Could you confirm that you have already tried these 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.

Hi Thays:  Thank you for your response.  

I can confirm that I have completed all the steps you listed above. I retested last night with matching firmware and software versions, but that did not help.  The working RIO worked fine and the problem RIO would not communicate over ethernet.  I used the same network cable, switch and laptop in my testing so all the non-RIO components were "known good".  I did try another computer as you suggested, both computers were able to connect fine to the good RIO but did not work with the problem RIO.

On the bad RIO the USB connections work fine and allows me to connect to the web dashboard, deploy code, connect with the driver station software, however when connected via the ethernet connection, it won't work.  From looking at the web dashboard (connected over USB) it doesn't even get an IP assigned to the ethernet adapter from the DHCP server.  Manually setting a Static IP using the web dashboard doesn't work either.  

With respect to your last point.  I have used the Robo RIO imaging tool to successfully update the software and firmware on the device a couple of times now, but I did not have the computer in safe mode while doing that. Is that what you are suggesting?  Or is there a way to put the RIO in safe mode while imaging?

I did re-load the software and Firmware on the RIO, while my laptop was in safe mode.  It didn't help, the Network adapter is still not functioning.

Hi Thays:

Haven't heard anythign in a few weeks.  Any next steps?  

Thanks,
