I agree that it is probably a simple networking thing. I can ping each of the addresses and the device pongs back. I did try to run the the benchmark program while specifying an IP address and USRP type and got the same error as shown below:\ \ /usr/local/lib/uhd/examples$ ./benchmark_rate --rx_rate 10e6 --tx_rate 10e6 --args "addr=192.168.10.2,type=x4xx"
