More often then not, the field is not to blame. They use super high quality equipment that for the most part does not lag or have traffic issues with a normal robot load. However, if you think it is for sure the field, you could talk with your FTA about looking through the log data on your robot. They may not be willing or able to, but you could try.
I would also recommend finding the NI Representative for your event and having them take a look.
good luck
