This is the output from an attempt to ping from a Windows 7 computer with an LTE modem plugged in.
The LED on the device tells me that the device has a data (IP) connection, but the Windows network adapter is not connected, and internet access is not possible.
Can anyone with more Ping or IP experience than me tell me what exactly the Ping result means? I am guessing that it means that the computer is able to reach another local node - what can I deduce from that?

This is the output from ipconfig for the network adapter:

Thanks Alen. I added the output from ipconfig above - there is no IP address shown. – user1725145 – 2012-11-30T13:47:53.573
There is also no IP address shown for any other network adapter, as they are all not connected. Could this IP address be the next node in the mobile network? – user1725145 – 2012-11-30T13:49:34.713
do ipconfig /all, it is possible that it is the static ip on you LAN card – rAlen – 2012-11-30T13:50:16.410
I did do ipconfig /all, don't want to post it all here, as I have clearly not mastered the art of laying it out properly...but there was no static IP address configured for the LAN card (or anywhere else). It occurred to me that this IP address might be the modem, although I have previously understood that the IP connection should end on the computer, and the modem shouldn't have its own IP address. – user1725145 – 2012-11-30T13:54:48.390
The modem is a usb stick with a connection to the LTE network. It makes an IP connection automatically when you plug the stick in, but you don't get internet access, and I'm trying to figure out why. – user1725145 – 2012-11-30T13:56:47.240
Your modem show media disconnected, so it cant be a next IP in the line of that connection as there isn't any connection, did you started the mobile connection in the software of the stick, I don't know about your LTE, but on my Vodafone stick the connection doesn't get started automatically, I have to started it manually – rAlen – 2012-11-30T13:57:36.773
I guess your stick a UMTS one? Do you know the model, and I could check? Under UMTS, the IP connection is started manually. But under LTE, the network sets up an IP connection as soon as you plug the stick in. The modem is showing that it has a data connection, it is the Windows network adapter that is media disconnected. – user1725145 – 2012-11-30T14:05:41.820
My stick isn't LTE, it is Huawei Mobile Connect E169 HSDPA, I have to start my connection in Vodafone Mobile Connect software, I don't know if your LTE works that way to – rAlen – 2012-11-30T14:09:24.773
The E169 makes a connection to the UMTS network using 3GPP protocols, and then it makes an IP connection when you click the connect button on the Vodafone software. But LTE is different - the modem makes an IP connection automatically when the stick is plugged in. The LED on the stick shows a data connection, but the network adapter in Windows is still media disconnected. And that's the connection for the ping result above - allegedly an IP connection, but Ping from the computer not possible. – user1725145 – 2012-11-30T14:16:50.047
if that is not an IP on your PC then it is probably a private IP on the LTE modem, I don't know why your modem doesn't make the connection to the Internet, or if it does why it doesn't route your traffic to it from the private side. Didn't use LTE in practice so can't help you there – rAlen – 2012-11-30T14:22:07.073
