Roborio 2 comms not working

[Cerbotics_4400]

Hi, we are experiencing networking issues with our RIO, we flashed the most recent images in various SDs but that doesnt seem to be the problem, the status light didnt show any problems.

At first when we tried connecting to it, nothing worked, we used usb b, direct ethernet conenction and wireless wifi but nothing, it didnt gave any comms at any time. Then somehow it worked for a while, but we had other problems like it connecting and disconnecting rapidly, communications lost at random times or code not deploying. And now were back to not being able to connect to it through anything. Any idea why this could be happening?

Hi Cerbotics_4400, thanks for posting on the forums. I'm Matthew with NI.

Intermittent connectivity can be a hassle to tack down, but let's see what we can find.
I would recommend using direct ethernet as much as possible for this as it should be the most reliable communication method.
You've mentioned SDs, so I'm assuming this is a roboRIO 2.0. If you just flash the SD (don't deploy any code), does communication behave better?
