What I have seen on my system (Windows 10):

1) Somebody, somewhere, is setting the "Connection-specific DNS Suffix" for the wireless adapter to "frc-robot.local" (see "ipconfig /all"). I don't know how this is happening but it looks broken to me. Radio firmware?

2) If you go to Control Panel->Network and Internet->Network and Sharing Center->Change Adapter Settings->(select) Wi-Fi->(tab)Change settings of this connection->(in dialog, select)Internet Protocol Version 4->Properties->Advanced->(tab)DNS, you'll see what appear to be a couple of ways to override the above setting:

a) Change "Append primary..." to "Append these..." and put "local" in the list.
-or-
b) Put "local" into the "DNS suffix for this connection" box.

In very limited testing either seems to work for me.

I am NOT a Windows expert (and wouldn't admit it if I were). If those who are disagree, trust them not me.

I've had success with this as well, but I haven't been able to vet it in all cases yet. I have to make my team rounds.
I had one case where it didn't help, because the PC suffix was wrong, but I didn't try adding frc-robot.local as an ending on that one.

Re: Can't connect to the robot

One more observation to throw into the mix: everything works for over Ethernet. Interestingly, if I ping the roboRIO over Ethernet, it uses an IPv6 address.

Also, further to my post about netsh: for us it works until we switch the wifi to the Internet. Then when we switch back it is all broken again.

The only solution we have which seems to work for eclipse and the drive station (and hopefully GRIP) is to set a static IP address on the roboRIO, then add all host name variants to the Windows host file.

This makes me very nervous though: What is going to happen when we get to competition? We really need a permanent solution to this soon.

Re: Can't connect to the robot

Don't know how to edit previous post sorry. We solved our problem by simply disabling all wifi connections on the PC except the robot and it connected perfectly. It appears the wifi connection to the internet on the PC was the problem.
