3. Connection and Settings
3.1. Router connection to the computer to set up
Before power supply insert the SIM card into the router. To do this you need to:
·Get out SIM tray by pressing the eject button on the SIM tray (fig.2.5.1) by long, thin
object (straighten paper clip, toothpick, etc.);
·Insert SIM card into the SIM tray;
·Insert SIM tray with SIM card into the router so that the edges of SIM tray got into the
holder slots.
Do not apply physical effort when you insert the SIM card. If necessary, insert the second SIM
card.
Connect GSM antenna and power cable. Use straight-through cable for connection to the
switching unit or a crossover cable when connecting directly to your computer. Supply the router
with power unit.
After power supply the router begins loading and load indicator is on. After load indicator is
off, the router is ready for use.
3.2. Basic Configuration
Web-based interface is used to configure the router and monitor its status. Source IP address is
192.168.1.1. Configuration can only be made by a user "root" with the initial password "root".
Web-interface top contains Status and log, Configuration and Administration tabs. Left part has
menu items for each tab.
3.2.1. Network Connection Settings
If the router iRZ RUH
2
3G is used for only one device Internet access, there is no need to
reconfigure the router network connection. You need only to configure the device properly: indicate
the IP address from the range of 192.168.1.2... 192.168.1.254, netmask 255.255.255.0 and default
gateway 192.168.1.1. You can also configure the device as DHCP-client. Then all these settings will
be received from the router automatically.
If the Internet connection is provided for the network, select such router settings to avoid
conflicts with the already connected devices. Consult your network administrator to obtain the
correct settings.
3.2.2. Access to web-interface
To configure the router, connect it directly to your computer using a crossover cable. Set
network connection properties "Automatically get IP address" in your computer. Enter 192.168.1.1

in the address line of the browser; click the link "iRZ RUH
2
3G Router". Enter username "root",
password "root" in the open window. Router web-interface will open. Click the tab "Configuration"
and select "LAN". You'll be directed to the router network connection configuration page. Available
options menu is on the left.
3.2.3. Configuring Network Connection Settings
Specify IP address of the router in the IP Address line. This address should be free in this local
network. If necessary, change the subnet mask (field "Subnet Mask") and specify the desired DHCP-
server settings. Note that if you want the computers in the network to use the Internet connection
established by the router, you need to indicate the IP address of the router as the default gateway in
the computers network settings. You may also need to specify IP address of the router in the field
"DNS server".
3.2.4. GSM Connection Configuring
Once the router is connected, and the network connection is set up, you can configure GSM
connection. To do this choose menu item "Internet" in web-interface tab "Configuration".
To make a connection with the Internet you need to know the access point name (APN),
username and password. This information can be obtained from your mobile operator. Indicate SIM
card number. Enter APN, Username and Password values in the appropriate fields. Click "Apply" to
save the settings and make a connection. After a while the connection will be established. Its status
can be checked on the tab "Status and log" in the menu item "Internet".
3.2.5. Settings reset
If, due to incorrect settings you cannot access the router interface, or you forgot your password,
you can revert to factory settings as follows:
·Switch on router;
·Press and hold the reset button (Figure 2.5.1);
·Reset is confirmed by triple flashing of load indicator;
·Release the reset button;
After resetting the device will be available at the address 192.168.1.1 with the username root
and password root.
