Strange mDNS behavior

On my machine, I often get into this state when connected to the robot via wireless:

1) I can ping roborio-488-FRC.local
2) I can ping roborio-488-FRC.lan

However, the FRC Driver Station has no comms. When I go to the diagnostics tab, the "Robot Radio" is green, but all other lights are not lit.

Pressing the arrow next to our team number in the Setup tab gives "None Found", even when shift-clicking.

The nimDNSResponder service is running.

If I plug in directly using USB, I have connection. Strangely enough, if I then pull out the USB cable I get "disconnected" for about 5-10 seconds, and then it connects (via wireless). This is a decent enough workaround, but still troubling.

Any suggestions? How can I debug this further?
