Hi Chris, Thanks for reply. I upgraded firmware from v4.1.0.5 to v4.1.0.6 RC1. I moved Netduino Plus to another router, no traffic running, just device and micro. Ping drops now only 3% messages and Hari´s app can run concurrently with continuous ping -t. Some bad interaction exists since after ping was frozen for 4 timeouts, I activated web server reloading command http://10.10.10.200/led/0 and ping restarted running. Most pings took 1-2 ms but largest reached 2662 ms, 41ms average, still a wide range, isn´t? It´s ok the static network setup as shown below for both routers. Enabling DHCP did not succeed and IP result was 0.0.0.0. I will stay tuned for TCP/IP stack improvements. Motta ------------------------ NetworkInterface[] networkInterfaces = NetworkInterface.GetAllNetworkInterfaces(); foreach (NetworkInterface networkInterface in networkInterfaces) { //networkInterface.EnableStaticIP("192.168.10.200", "255.255.255.0", "192.168.10.254"); networkInterface.EnableStaticIP("10.10.10.200", "255.255.255.0", "10.10.10.1"); //networkInterface.EnableDhcp(); //networkInterface.RenewDhcpLease(); Debug.Print("Gateway Address: " + networkInterface.GatewayAddress); Debug.Print("IP Address: " + networkInterface.IPAddress); Debug.Print("Subnet mask " + networkInterface.SubnetMask); }

Hi. Great device, great IDE and nice job fom SecretLabs. I see many apps coming! I loaded Hari´s code to my new N+ and applied pathches to get static IP from yaksplat and also delay suggested by myszor. I´ve got same unstable results and sometimes N+ do not answer and browser got frozen. Another test may help to figure out what is happening: opening a DOS windows from a separate micro and running a continuous ping -t shows 20% loss due to a timeout which means that N+ is not answering ICMP as well. Any hints that help to fix this are welcome. Thanks
