If you are using a gigabit switch i.e your LAPTOP/PC is connected to gigabit switch and USRP is connected to gigabit switch then there should not be any problem. If you don't fine an extra cable, you can test Ethernet cable by connecting a PC/router and pinging it. Please see following links for your question on netmanager and dhcp: http://askubuntu.com/questions/21654/how-to-tempor... http://www.ubuntugeek.com/change-ubuntu-system-fro... Hope it helps. >>>>Hi Marcus, >>>> I have not changed the fpga firmware. I used the build-gnuradio script to install gnuradio. I am not finding another ethernet cable in the lab.

Marcus and Sam, I brought a working ethernet cable and connected it from my laptop to the switch.I changed my network manager settings to use only static ip by modifying /etc/network/interfaces file. I still can't get uhd_find_devices script nor uhd_usrp_probe script. It still says uhd device not found. My usrp shows D and F Led's glowing. so i think that means firmware is loaded. what could be the problem? should i go ahead and reinstall it?

With the device in that state, can you ping it? -- Marcus Leech Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org
