Open the Control Panel from the Windows^® icon in the lower left corner of your monitor.

In the Control Panel window, make sure View by is set to Category.

Click Network and Internet.

Click Network and Sharing Center.

Click Change adapter settings in the left pane.

Double-click the adapter to configure its properties.

On this computer, the adapter with the name Ethernet indicates connectivity to the Internet, but the connectivity of Ethernet 2 indicates No network access. Double-click the Ethernet 2 adapter to open its properties.

On the Networking tab, clear Clients for Microsoft Networks and File and Printer Sharing for Microsoft Networks. These services can cause intermittent connection problems with USRP radios. To configure the IP address, double-click Internet Protocol Version 4 (TCP/IPv4).

On the General tab, the default setting is typically set to Obtain an IP address automatically.

Select Use the following IP Address. Set the host IP address to 192.168.10.X, where X is any integer from 1 to 255 except 2. Leave the Subnet mask set to its default (255.255.255.0).

If your radio is on another subnet, meaning the first three octets of the IP address field are not 192.168.30, then enter the IP address values of your radio for the first three octets. See Check Subnet Values on Host and Radio.

Click OK.

The host computer configuration is complete. Continue to Verify USRP Hardware Connection.

Determine which Ethernet adapter is used for the internet connection by pinging the IP address associated with each Connection Name returned. When you identify the connection name of the network adapter connected to the Internet, avoid selecting that network adapter for the radio. For more information, see Host Machine Checklist.

The host computer in this example uses the "Ethernet" connection name for the Internet connection. Run the netsh command with this syntax to get the IP address of "Ethernet". Then ping that IP address to a website. Since the host computer uses this network adapter for its internet connection, reconfiguring this adapter to connect to the radio would jeopardize your ability to connect to the Internet. See Using One Ethernet Port.

Next we run the netsh command specifying the "Ethernet 2" connection name. DHCP is typically enabled for an adapter that is not statically configured. Since the host computer does not use this network adapter for its internet connection, reconfiguring this adapter to connect to the radio, does not jeopardize your ability to connect to the Internet. That makes it a good adapter to use for the host-to-radio connection.

C:\>netsh interface ip show address "Ethernet 2"

Configuration for interface "Ethernet 2"
  DHCP enabled: Yes
  InterfaceMetric: 5

Connect the radio to this USB-Ethernet adapter. Wait for a few seconds, and then check the setting again. The response for a successful host-to-radio connection resembles the output shown here.

C:\>netsh interface ip show address "Ethernet 2"

The IP address 169.254.55.226 is a private IP address automatically assigned by Windows to the Ethernet adapter. To discover the IP address of your radio, ping the broadcast address 169.254.255.255. This address corresponds to the subnet prefix 169.254.0.0. The response for a successful ping resembles the output shown here.

Approximate round trip times in milli-seconds:
  Minimum = 1ms, Maximum = 2ms, Average = 1ms

Based on the discovered radio IP address 192.168.30.7, assign an IP address to the Ethernet adapter from the same subnet, such as 192.168.30.1. Use a subnet mask of 255.255.255.0.

C:\>netsh interface ip set address "Ethernet 2" static 192.168.30.1 255.255.255.0

Set the correct host computer network interface IP address. USRP radios have a factory default IP address of 192.168.10.2. Leave the subnet mask set to its default (255.255.255.0).

If the USRP radio IP address is the default value of 192.168.10.2, run this shell command to set these values.

%sudo ifconfig ethX 192.168.10.Y netmask 255.255.255.0

ethX is the name of the host computer Ethernet port (usually eth0, eth1, etc.), and Y is any integer from 0 through 255 excluding 2. You might be required to enter a password to use the sudo command.

If your radio is on another subnet, meaning the first three octets of the IP address field are not 192.168.30, then enter the IP address values of your radio for the first three octets. See Check Subnet Values on Host and Radio.

This example shows this workflow in detail. Use these commands to determine the IP address of the radio. After determining the IP address for the radio, update the network interface IP address, and ping the radio to verify that the host-to-radio connection is working.

Run these shell commands to configure the network connection, and then check that the changes took effect.

%sudo ifconfig eth X 192.168.Y.Z
ifconfig ethX

For 192.168.Y.Z use the actual IP address to be assigned to the host computer, and for ethX use the name of the host Ethernet port (usually eth0, eth1, etc.).

On Linux systems, unless you make network connection changes persistent, a system reboot resets network connection changes, and the host-to-radio connection is lost. To retain the host-to-radio connection after a computer reboot, see Make Changes Persistent on Linux.

The host computer configuration is complete. Continue to Verify USRP Hardware Connection.

Click Network from System Preferences. From the left pane, select the network connection that is connected to the USRP radio. If your Mac has only one network interface card (NIC), see Using One Ethernet Port.

The default IPV4 configuration is Using DHCP. The default IP address 169.254.142.233 is a private IP address automatically assigned by the operating system. For more information, see https://tools.ietf.org/html/rfc3927.

Set Configure IPv4 to Manually. Set IP Address to 192.168.10.X, where X is any integer from 1 to 255 except 2, and Subnet Mask to 255.255.255.0. Click Apply.

If your radio is on another subnet, meaning the first three octets of the IP address field are not 192.168.30, then enter the IP address values of your radio for the first three octets.

The host computer configuration is complete. Continue to Verify USRP Hardware Connection.
