Troubleshooting a Data Problem
If you are unable to access the Internet, follow these steps:
Step 1: Check the Basics
Complete the initial steps described in
“Initial Steps for Any Problem”
.
Step 2: Check Your Computer’s DHCP Configuration
Unless you have set up a static IP address, your computer’s TCP/IP
settings need to be configured for DHCP addressing, which allows the
ICM to assign it an IP address. Refer to
Step 3: Try a Direct Wired Connection
Connect your computer directly to the “User Ethernet 1” port on the
back of the ICM using an Ethernet cable. Then restart your computer.
If you are now able to access the Internet, there is a problem with your
vessel’s network.
Step 4: Ping the Network Connections
The Ping command sends a test packet to any IP address you choose
and reports how long it takes to receive a response.
To send a Ping on a Windows PC:
Open a Command Prompt window
(press Windows Logo key + R, then
type
cmd
)
. Then, at the command prompt, type
ping <IP address>
.
To send a Ping on a Mac:
Open the Network Utility
(go to Finder > Utilities > Network Utility)
.
Then, in the Ping tab, type the IP address then click
Ping
.
Ping the IP address of the ICM. You can find the IP address on the
front panel LCD
(go to Settings > Network Settings > IP Assignments)
.
The default IP address is
192.168.5.1
. All packets sent should be
received. If packets are lost, your computer is not connected properly
to the ICM.
Ping
4.2.2.1
to check your connection to the Internet. All packets sent
should be received within 580-900 ms. If the ping fails, contact KVH
