Competition Tethering Issue

[Mattpenguin]

Our team is competing at the Bayou regional, and we began having strange connection issues towards the end of the day after we connected to the field. We connected to the feild fine, and returned to the pit to push a new version of code, which was also successful. Later, we went to the particle field and we were unable to get commms with the Driver Station, however we were able to ping the D-link, ping the roboRIO, and push code perfectly fine, we were just unable to get any sort of communication via the DS. We tried multiple Ethernet Cables, rebooting the robot, and setting static IP's on the driver laptop. Any help would be greatly appreciated, and if any more information or clarification is need feel free to let me know
