The first step to identifying roboRIO networking issues is to isolate if it is an application issue or a general network issue. To do this, click **Start -> type cmd -> press Enter** to open the command prompt. Type ``ping roboRIO-####-FRC.local`` where #### is your team number (with no leading zeroes) and press enter. If the ping succeeds, the issue is likely with the specific application, verify your team number configuration in the application, and check your firewall configuration.

If there is no response, try pinging ``10.TE.AM.2`` (:ref:`TE.AM IP Notation <docs/networking/networking-introduction/ip-configurations:TE.AM IP Notation>`) using the command prompt as described above. If this works, you have an issue resolving the mDNS address on your PC. The two most common causes are not having an mDNS resolver installed on the system and a DNS server on the network that is trying to resolve the .local address using regular DNS.
15

16
+
- Verify that you have an mDNS resolver installed on your system. On Windows, this is typically fulfilled by the NI FRC Game Tools. For more information on mDNS resolvers, see the :ref:`roboRIO Networking article <docs/software/roborio-info/roborio-web-dashboard:roboRIO Web Dashboard>`.

- Disconnect your computer from any other networks and make sure you have the OM5P-AN configured as an access point, using the :ref:`FRC Radio Configuration Utility <docs/zero-to-robot/step-3/radio-programming:Programming your Radio>`. Removing any other routers from the system will help verify that there is not a DNS server causing the issue.
If pinging the IP address directly fails, you may have an issue with the network configuration of the PC. The PC should be configured to **Automatic**. To check this, click :guilabel:`Start` -> :guilabel:`Settings` -> :guilabel:`Network &Internet`. Depending on your network, select :guilabel:`Wifi` or :guilabel:`Ethernet`. Then click on your connected network. Scroll down to **IP settings** and click :guilabel:`Edit` and ensure the :guilabel:`Automatic (DHCP)` option is selected.
If pinging the IP address directly fails, you may have an issue with the network configuration of the PC. The PC should be configured to **Obtain an Address Automatically** (also known as DHCP). To check this, click :guilabel:`Start` -> :guilabel:`Control Panel` -> :guilabel:`Network Connections` -> :guilabel:`Change adapter settings`, then right click on the appropriate interface (usually Local Area Connection for Ethernet or Wireless Network Connection for wireless) and select :guilabel:`Properties`. Click :guilabel:`Internet Protocol Version 4`, then click :guilabel:`Properties`. Make sure both radio buttons are set to :guilabel:`Obtain automatically`.

If this ping succeeds, but the .local ping fails, it is likely that either the roboRIO hostname is configured incorrectly, or you are connected to a DNS server which is attempting to resolve the .local address.

If you are troubleshooting an Ethernet connection, it may be helpful to first make sure that you can connect to the roboRIO using the USB connection. Using the USB connection, open the :ref:`roboRIO webdashboard <docs/software/roborio-info/roborio-web-dashboard:roboRIO Web Dashboard>` and verify that the roboRIO has an IP address on the ethernet interface. If you are tethering to the roboRIO directly this should be a self-assigned ``169.*.*.*`` address, if you are connected to the OM5P-AN radio, it should be an address of the form ``10.TE.AM.XX`` where TEAM is your four digit FRC team number. If the only IP address here is the USB address, verify the physical roboRIO ethernet connection.
