One thing it to ensure that your card is running at gigabit speed and not auto-negotiated to 10/100 and not 1000. Since your on linux you could run iftop and watch the connection speed. You can also verify the speed with mii-tool. My interface is called enp7s0:address@hidden ~]$ sudo mii-tool -v enp7s0enp7s0: negotiated 1000baseT-FD flow-control, link okproduct info: vendor 00:07:32, model 17 rev 4basic mode: autonegotiation enabledbasic status: autonegotiation complete, link okcapabilities: 1000baseT-HD 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HDadvertising: 1000baseT-HD 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-controllink partner: 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-controlIf your interface is running at the wrong speed you may want to try a direct connection to the USRP, a new cable, or worse case a new network card.Best of luck,Jeff N6SDROn Tue, Mar 19, 2013 at 12:30 AM, john jade <address@hidden> wrote:

I just connected UHD source block to FFT sink in my example.My system specifications.Thanks
