7. TROUBLESHOOTING
This section lists some of the most common problems occurred while setting up the Vanguard 3G
unit and troubleshooting tips to fix the problem.
Cannot Connect to the Home Page
Step 1:
Open a DOS command prompt on your PC. (Start - > Programs -> Accessories->Command
Prompt_
Enter the command “ipconfig” at the prompt. This will display all IP information assigned to
the PC including the IP address, subnet mask and gateway.
The Default gateway should be “192.168.1.50” if you are using a new Vanguard 3G unit or
should be whatever was assigned as the Ethernet IP of the Vanguard 3G unit during previous
configurations.
If this is the address, skip to step 2.
If the address is other than expected, but is a private IP (see Network basics) and the IP
address and gateway are on the same subnet, enter that address in a browser to establish
connection. If this does not fix the problem, skip to step 2.
If the gateway is not the expected value and does not follow the above format:
1. Close all active browsers
2. On the “Network and Dial-Up Connections Page” confirm that the network settings are set
to automatically detect an IP and DNS server.
3. Verify that there are no other active connections; specifically be sure that all wireless
cards are disabled.
4. Disable, and then Re-enable the network connection. (Some older versions of Windows do
not update network setting automatically, you need to re-enable the network settings or
restart the PC to set updated network settings.)
5. Enter “ipconfig” in the command prompt; verify that the Default gateway is now correct.
6. Enter the gateway IP address into a browser, if this does not fix your problem skip to step
2. If the gateway is still not in the correct format, skip to step 3.
Step 2:
Enter “ipconfig” in the command prompt as instructed above. The IP address should be of
the format 192.168.1.xxx if you have new unit or should be on the same subnet if you have
changed the Ethernet IP, but should not be the same as the Default gateway. If the
address is in the correct format and not the same as the Gateway, skip to step 3.
If it is not correct, open the properties window of the network connection. Manually enter a
unique IP address on the same subnet as the gateway (use 192.168.1.100 if you have not
changed the default) and save the properties. (Note: You may need to disable/re-enable the
connection to get the new settings to take effect). This should allow you to connect to the
device. Once you are connected, check the DHCP settings; the DHCP server may be disabled.
Step 3:
Check the following
1. Confirm you are using a working Ethernet cable. Try a different Ethernet cable if
necessary.
2. Confirm the Ethernet port you are plugging into on your PC is active.
3. Confirm power supply for your unit is functioning. Refer to LED behavior (section
2.5.2).
