Forum: GNU Radio Re: uhd_find_devices issue

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:

Hope it helps.

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?
