If you shift-click (or maybe just click) the down arrow next to the team number in the driver's station, that causes a new mDNS query to go out. See if there is anything listed there when it can't communicate. It should be all robot names detected on the network.

mDNS has caused issues in the past for us. That's why we switched to static. We think we know the ramifications of it.
