If you are unable to access the Internet, follow these steps:
Complete the initial steps described in Initial Steps for Any Problem.
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 CommBox-ACU to assign it an IP address. Refer to Configuring Computers for DHCP for details.
Connect your computer directly to the “User Ethernet 1” port on the back of the CommBox-ACU 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.
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 CommBox-ACU. 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 CommBox-ACU.
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 Technical Support (see Contacting KVH Technical Support).
