Networking Tips and Troubleshooting

RoboRIO connectivity

  • USB: 172.22.11.2
  • Wifi or Ethernert (mDNS connecting through the radio): roboRIO-TEAM-FRC.local (ex: ping roboRIO-3528-FRC.local)
  • Ethernet directly into the RoboRIO: self-assigned link-local address (169.254.0.0/16)

Common FRC IP Addresses

  • Radio: 10.TE.AM.1
  • RoboRIO Static: 10.TE.AM.2
  • RoboRIO USB: 172.22.11.2
  • RoboRIO mDNS: roboRIO-####-FRC.local
  • RoboRIO ethernet: DHCP
  • DHCP Range: 10.TE.AM.20 – 199
  • IP Networking at the Event

Command-line network setup (useful for scripting)

(This not as necessary with the RoboRIO since most everything is configured automagically using mDNS.)

Run the following from an admin command prompt:

netsh interface ip set address name="Wireless Network Connection" static <ip address> <netmask> <gateway>

Replace:

  • <ip address> with your desired ip address (example: 10.35.28.42)
  • <netmask> with your desired netmask (usually: 255.0.0.0)
  • <gateway> with your desired gateway (example: 10.35.28.2)

(You’ll need to modify the ip addresses to use your team number. You may need to change the name of your wireless card as well.)

In times of (network) trouble

  • Make sure mDNS is running
  • Make sure you can ping your router/radio
  • Make sure you can ping roboRIO-TEAM-FRC.local (ex: ping roboRIO-3528-FRC.local)
  • Disable Windows or other installed Firewalls
  • Disable all other network adapters except the one you’re connecting to the robot
  • Switch to a wired connection
  • Try USB

If you get errors deploying code but it works with the firewall off, disable stateful ftp blocking. Run the following in an admin command window:

netsh advfirewall set global StatefulFTP disable
