Hi I installed and was working with gnuradio for some time now. Suddenly from two days i find that my device is not being detected. I run uhd_find_devices or uhd_fft , I get uhd device not found. I checked my network connections and set sudo ifconfig eth0 192.168.10.1 and also checked that it's subnet mask is set to 255.255.255.0. But my eth 0 shows no received packets. I have attached the screenshot of it. when i try to run uhd_fft and uhd_find_devices it says no uhd device found.I have attached the screenshot of the same too. what could be the problem. I am sure the installation is right because my grc is opening and i worked on it a few days back.
