This is what an unsuccessful ping from the end-user’s PC to the EUM looks like:
C:\>ping 169.254.10.250
Pinging 169.254.10.250 with 32 bytes of data:
Request timed out.

Ping statistics for 169.254.10.250:
Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms
Verify DHCP
This step is for networks that use DHCP to provide IP addresses to the end-user’s computer.
Assuming the Setup command shows that the modem has registered with a CCU and is
receiving a signal, then reconfigure the end-user PC to use the correct IP address. This is
usually done using DHCP to automatically obtain the IP address.
On Windows 2000, XP and similar systems, the IP Address is set using the Control Panel >
Network and Dialup Connection > Local Area Connections > right mouse click to select
Properties > Internet Protocol (TCP/IP) > Properties. To enable DHCP, click on the “Obtain an
IP Address Automatically” button.
Once properly configured, verify the end-user has received an IP address. For a Windows
2000 or XP PC, in a DOS Window, type “ipconfig” and see that there is an IP address
assigned along with a Gateway Address and DNS server addresses This confirms that the
End user PC is contacting the DHCP server correctly. Record the IP Address of the gateway
and the DNS servers.
Ping the Gateway
Ensure the end-user’s PC is configured properly. Then ping the EUM gateway address from a
PC DOS window. The gateway address was recorded during the Verify DHCP address is
using DHCP. Otherwise the installer will know the gateway address since it is needed to
configure the end-user’s PC.
Ping using short packets first (default size) to confirm the connection. Then use long packets
(1472 byte packets) to confirm the RF performance. Errors observed on pings with long
packets indicate a high error rate on the channel, caused by low signal levels or interference.
The following describes how to ping the gateway:
1. Open a DOS window.
2. At the command prompt, type ping <aaa.bbb.ccc.ddd> -t -l 1472, where
<aaa.bbb.ccc.ddd> is the Gateway radio IP address and press Enter.
3. Press Ctrl+c to end the test.
