Re: Can't communicate with cRIO or d-link on power on

The arp command returned a list of devices, the IP's and MAC addresses were visible for the cRIO, Router and Laptop. Interestingly enough the router's type showed invalid which changed to dynamic when the ethernet cable from the cRIO was removed and reinserted. The laptop and cRIO are listed as static, no device shared the same MAC address.

Interestingly enough, in our troubleshooting we tried to format the cRIO with the imaging tool which failed multiple times and we couldn't get it to work for hours until we removed power from the digital and analog sidecars, then the format worked instantly. Afterwords we could not repeat our problem at all, every cold boot resulted in an instant connection. We tested powering on again multiple times with different side carts and modules and couldn't recreate the problem. The problem returned immediately after uploading our robot code to the cRIO, even if we just tried the simple robot template the problem continued.

Competition is in a few days and I am desperate for an answer of any kind, so the help is appreciated.

Thanks
