Why Doesn't the Device IP Address Reset to the Default?

If you cannot reset the default device IP address, your device may be on a different subnet than the host network adapter. You can power cycle the device in a safe (read-only) image, which sets the device to the default IP address of 192.168.10.2.
  1. Open the device enclosure, making sure to take appropriate static precautions.
  2. Locate the safe-mode button, a push-button switch (S2), inside the enclosure.
  3. Press and hold the safe-mode button while you power cycle the device.
  4. Continue to press the safe-mode button until the front panel LEDs blink and remain solid.
  5. While in safe-mode, run the NI-USRP Configuration Utility to change the IP address from the default, 192.168.10.2, to a new value.
  6. Power cycle the device without holding the safe-mode button to return the normal mode.
    Note NI recommends that you use a dedicated network with no other USRP devices connected to the host computer to avoid the possibility of an IP address conflict. Also, verify that the static IP address of the host network adapter on the computer that runs the NI-USRP Configuration Utility is different from the device default IP address of 192.168.10.2 and different from the new IP address to which you want to set the device.
    Note If the device IP address is on a different subnet from the host network adapter, the host system and configuration utility cannot communicate with and configure the device. For example, the utility recognizes, but cannot configure a device with an IP address of 192.168.11.2 connected to a host network adapter with a static IP address of 192.168.10.1 and a subnet mask of 255.255.255.0. To communicate with and configure the device, change the host network adapter to a static IP address on the same subnet as the device, such as 192.168.11.1, or change the subnet mask of the host network adapter to recognize a wider range of IP addresses, such as 255.255.0.0.
