19
H7921-RHZ-i 3G Router User Manual
Fig. 3.2.3-3: TCP/IP Properties Configuration
Method 1: general configuration
This method will temporarily interrupts the communication between the computer
under configuration and LAN, and the specific parameter configuration is shown as
below:
IP address: 192.168.8.* (*indicates any integral between 2 to 254)
Subnet mask: 255.255.255.0
Default gateway: 192.168.8.1
Remember:
Galaxy H7921-RHZ-i 3G Router LAN port factory default parameter:
IP address: 192.168.8.1;
Subnet mask: 255.255.255.0
Galaxy H7921-RHZ-i 3G Router factory default login parameter:
Management interface login IP address: 192.168.8.1
Login name: admin
Login password: admin
Method 2: advanced configuration
20
H7921-RHZ-i 3G Router User Manual
If you don’t want to interrupt local PC LAN communication and configure Galaxy
H7921-RHZ-i 3G Router when the former network configuration exists, it is required
add route (IP).
The configuration operation is shown as below:

21
H7921-RHZ-i 3G Router User Manual
After the configuration is completed, click the “Add”. By now the computer has a route
to Galaxy H7921-RHZ-i.
Note:
As shown in Fig. 3.2-3, “Default gateway” depends on whether the configuration
computer connects with Internet through original local network configuration. If
Internet is accessed through original local network, the default gateway setting does
not need to be modified; if Galaxy H7921-RHZ-i 3G Router + is used, you need to
modify the default gateway and configure it as Galaxy H7921-RHZ-i 3G Router’s
default LAN IP address 192.168.8.1.
2. Network check

Step 1: IP configuration check
Use the command of ipconfig to check whether the IP address is correctly set or added.
You can enter DOS mode and key-in command: ipconfig, for instance:
C:\>ipconfig
Windows IP Configuration
Ethernet adapter local connection:
Connection-specific DNS Suffix. :
Auto configuration IP Address . . .: 192.168.8.7
Subnet Mask . . . . . . . . . . .: 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.8.1

Step 2: connectivity check
After the configuration is completed, you can check the connectivity between it and
Galaxy H7921-RHZ-i 3G Router by ping command. Key-in ping command in system
command line:
Ping 192.168.8.1
If the following information appears:
Pinging 192.168.8.1 with 32 bytes of data:
Reply from 192.168.8.1: bytes=32 time=2ms TTL=64
Reply from 192.168.8.1: bytes=32 time=2ms TTL=64
By now, it means that the configuration computer has been connected to the router. You
can carry out configuration operation on it.
3.2.4 System login
Open the IE browser, and input http://192.168.8.1/ in address bar, as shown below:
