Thanks for your help. I've got it to work. I had the Netduino Ethernet cable connected to the Ethernet connection on the back of the Wifi Router that allows me to use access the Internet throughout my home. The Netduino Ethernet cable needed to be connected directly to the cable Modem that connects directly to the Internet. Ken

Continuing to try to run "HelloPachube" It seems obivious that I cannot get to the Internet from the Ethernet. I've disabled Windows Defender and turned off the firewall. Still the same problem. Ken

Everything looks good up until about 20 seconds after: new message: voltage,2.66 time: 01/01/2009 00:10:40 memory available: 20172 I get the following: #### Exception System.Net.Sockets.SocketException - CLR_E_FAIL (1) #### #### Message: #### Microsoft.SPOT.Net.SocketNative::getaddrinfo [IP: 0000] #### #### System.Net.Dns::GetHostEntry [IP: 0008] #### #### System.Net.HttpWebRequest::EstablishConnection [IP: 00e1] #### #### System.Net.HttpWebRequest::SubmitRequest [IP: 0013] #### #### System.Net.HttpWebRequest::GetRequestStream [IP: 0008] #### #### Gsiot.PachubeClient.PachubeClient::CreateRequest [IP: 003e] #### #### Gsiot.PachubeClient.PachubeClient::Send [IP: 0025] #### #### HelloPachube::Main [IP: 0065] #### #### SocketException ErrorCode = 10060 #### SocketException ErrorCode = 10060 A first chance exception of type 'System.Net.Sockets.SocketException' occurred in Microsoft.SPOT.Net.dll #### SocketException ErrorCode = 10060 #### SocketException ErrorCode = 10060 #### Exception System.Net.WebException - 0x00000000 (1) #### #### Message: host not available #### System.Net.HttpWebRequest::EstablishConnection [IP: 00f1] #### #### System.Net.HttpWebRequest::SubmitRequest [IP: 0013] #### #### System.Net.HttpWebRequest::GetRequestStream [IP: 0008] #### #### Gsiot.PachubeClient.PachubeClient::CreateRequest [IP: 003e] #### #### Gsiot.PachubeClient.PachubeClient::Send [IP: 0025] #### #### HelloPachube::Main [IP: 0065] #### A first chance exception of type 'System.Net.WebException' occurred in System.Http.dll A first chance exception of type 'System.Net.WebException' occurred in System.Http.dll System.Net.WebException: host not available sleep for 8587 ms I get this same message if I remove the Ethernet cable and run debug Hellopachlub. I have the API key in quotes and the feed ID in quotes. my Pachube account looks good though it seems they want triggers added to the two datastreams. mfDeploy seems ok with mac address intentered and DHCP checked Pinging I get: Pinging...
