USRP2 MatLab Implementation Problem

I am having two systems with Matlab R2010b,I configured IP as 192.168.10.1 and 192.168.20.1 for each.By using simple tx and simple rx example i tried to transmit and receive signal thru usrp2.what ever i transmitted using simple tx usrp2 is not detected by simple rx usrp2.In both the systems simple Tx example is working fine(i checked with spectrum analyzer the signal transmitted it works fine,also both the usrp2 are workin fine).I am using WBX daughterboard and VERT900 antenna for transmission and reception. Also only using the IP 192.168.10.255 and 192.168.20.255 i am able to communicate to USRP2 in simulink and not using 192.168.10.2. Suggestions please.

Hi,

How did you get to the stage of connecting the usrp2 in Rx mode. I was trying to run the provided demos with no luck. Not sure if I need to upload the GNU software to the SD card reader aswell as the usual USRP2 firmware found on: http://www.mathworks.com/support/solutions/en/data/1-CUN7JZ/?solution=1-CUN7JZ

Any advise or comments would be apreciated.

If yes to the GNU software, where would I locate this, and which ones would I need?
