10.3 Troubleshooting Ethernet Problems
After reconfiguring the ethernet settings you experience problems accessing the EMB HubLite with your
web browser, check the following items.
•
Verify that you rebooted the EMB HubLite after making the changes to the network settings.
• Use the EMB HubLite LCD console. Check the IP address and Netmask. Verify these are correct.
• Verify the ethernet link/act light next to the Ethernet port is on. It should blink with activity.
•
Verify the network connection in your computer has the proper IP address, on the same subnet, to
access the EMB HubLite. NOTE: one common mistake is configuring the Laptop IP to the same address
as the IP address of the EMB HubLite. In order for the laptop and EMB HubLite to communicate, the IP
addresses should not be identical. (See the basic network config for suggested IP addresses.)
•
Use the LCD console to run the Network Status test. This will attempt a number of things including
a ping query to the gateway address. If the EMB HubLite can ping an external machine such as a
gateway, the ethernet port is most likely connected properly. If the EMB HubLite does not use a gateway,
try adding a gateway address , and make it the address of your computer.
