 AirCard Smart Cradle
Test the LAN Path to Your Smart Cradle
You can ping the cradle from your computer to verify that the LAN path to your cradle is set 
up correctly.
To ping the cradle from a Windows computer:
1. 
From the Windows toolbar, click Start and select Run.
2. 
In the field provided, type ping followed by the IP address of the cradle, as in this 
example:
ping http://192.168.100.1
 
3. 
Click the OK button.
You see a message like this one:
Pinging <IP address > with 32 bytes of data
If the path is working, you see this message:
Reply from < IP address >: bytes=32 time=NN ms TTL=xxx
If the path is not working, you see this message:
Request timed out
If the path is not functioning correctly, you might be experiencing one of the following 
problems:
Wrong physical connections
For a wired connection, make sure that the numbered LAN port LED is lit for the port to 
which you are connected.
Check that the appropriate LEDs are on for your network devices. If your cradle and 
computer are connected to a separate Ethernet switch, make sure that the link LEDs are 
lit for the switch ports that are connected to your computer and cradle.
Wrong network configuration
Verify that the Ethernet card driver software and TCP/IP software are both installed and 
configured on your computer. 
Verify that the IP address for your cradle and your computer are correct and that the 
addresses are on the same subnet.
Test the Path from Your Computer to a Remote Device
After verifying that the LAN path works correctly, test the path from your computer to a remote 
device.
1. 
From the Windows toolbar, click the Start button and select Run.
2. 
In the Windows Run window, type
ping -n 10 
<IP address>
