WARP Project Forums - Wireless Open-Access Research Platform

I am getting error when i run this chunk of code in matlab 2011a,
clear
N = 1;
nodes = wl_initNodes(N);
wl_nodeCmd(nodes,'identify');
disp(nodes)

The procedure i followed is as follows...
First i run wl_setup.m file in matlab,

I also attach the putty terminal output,

The My wl_config.ini file is showing,

When i run arp -a in command prompt the result is like this

Suggest me how to make this work by using 100Mb ethernet switch?
How to rectify this error??
