[Discuss-gnuradio] RuntimeError: No USRPs found on interface eth0

Hello,
I am using USRP2 with a EEE PC (1015PX) which has ubuntu 11.04 on it. Since the USRP2 communicates only gigabit, I bought a Linksys SE2800 Gigabit Ethernet switch and connected the USRP2 via the Ethernet Switch (The EEE PC does not have a gigabit ethernet card). I switched on the USRP2 and I got the D and F led lights on after all the led lights flashing. I run the usrp2_fft.py program and I got this error:
address@hidden:~# usrp2_fft.py Traceback (most recent call last): File "/usr/bin/usrp2_fft.py", line 273, in <module> main () File "/usr/bin/usrp2_fft.py", line 269, in main
app = stdgui2.stdapp(app_top_block, "USRP2 FFT", nstatus=1) File "/usr/lib/python2.7/dist-packages/gnuradio/wxgui/stdgui2.py", line 36, in __init__ wx.App.__init__ (self, redirect=False)

File "/usr/lib/python2.7/dist-packages/gnuradio/wxgui/stdgui2.py", line 60, in __init__ self.panel = stdpanel (self, self, top_block_maker) File "/usr/lib/python2.7/dist-packages/gnuradio/wxgui/stdgui2.py", line 81, in __init__

return _usrp2.source_32fc(ifc, mac) RuntimeError: No USRPs found on interface eth0
Then I tried to ping the usrp2 by connecting it to my laptop which has a gigabit ethernet, but I don't get any response from it. The request is timed-out everytime. I also tried all the solutions possible from the list, nothing works for me.
Please Help.
