Troubleshooting

Overview
This chapter covers some common problems that may be encountered

while using the XC-DPG602 and some possible solutions to them. If you

follow the suggested steps and the XC-DPG602 still does not function

properly, contact XiNCOM for further advice.

General Problems

Problem: I can’t connect to the XC-DPG602 to conﬁgure it.
Solution: Check the following:

The XC-DPG602 is properly installed, LAN connections are OK, and

the device is powered ON.
Ensure that your PC and the XC-DPG602 are on the same network

segment.
If your PC is set to Obtain an IP Address automatically (DHCP

client), restart it.
If your PC uses a Fixed (Static) IP address, ensure that it is using an

IP Address within the range 192.168.1.2 to 192.168.1.254 and thus

compatible with the XC-DPG602’s default IP Address of 192.168.1.1.
Also, the Network Mask should be set to 255.255.255.0 to match the

XC-DPG602.
In Windows, you can check these settings by using Control Panel-

Network to check the Properties for the TCP/IP protocol.

Internet Access

Problem 1: When I enter a URL or IP address I get a time out error.
Solution 1: A number of things could be causing this. Try the following

troubleshooting steps:

Check if other PCs work. If they do, ensure that your PCs IP

settings are correct. If using a Fixed (Static) IP Address, check

the Network Mask, Default gateway and DNS as well as the IP

Address.
If the PCs are conﬁgured correctly, but still not working, check the

XC-DPG602. Ensure that it is connected and ON. Connect to it and

check its settings. (If you cannot connect to it, check the LAN and

power connections.)
If the XC-DPG602 is conﬁgured correctly, check your Internet

connection (DSL/Cable modem etc) to see that it is working

correctly.

Problem 2: Some applications do not run properly when using the XC-

DPG602.

Solution 2: The XC-DPG602 processes the data that passes through it and

therefore it does not act as a transparent device.

Use the Special Applications feature to allow the use of Internet

applications which do not function correctly.
If this does solve the problem you can use the DMZ function. This

should work with most applications, but:

• It is a security risk, since the ﬁrewall is disabled for the DMZ PC.
• Only one (1) PC can use this feature.
