1 Introduction
Thank you for purchasing a CASE6904 4G / LTE router!
The CASE6904 is part of the CASE range compact mobile routers with high speed wireless and
Ethernet connections.
This router is ideal for people who‘d like to share their internet on the go, as it is not restricted
by a cumbersome cable connection. Unrestricted, but not forgotten: the router still supports
internet distribution via a broadband cable, simply plug it in to the wan port, set the router to a
correct mode and you are ready to browse.

3.0. Installation
After you unpack the box, follow the steps, documented below, in order to properly connect the
device. For better Wi-Fi performance, put the device in clearly visible spot, as obstacles such as
walls and door hinder the signal.
1. First assemble your router by attaching the necessary antennas and inserting the SIM
card.
2. To power up your router, please use the power adapter included in the box.
(IMPORTANT: Using a different power adapter can damage and void the warranty for
this product.).
3. If you have a wired broadband connection you will also have to connect it to the WAN
port of the router
3.1. Front and Back Panel of the Case 6904 Router

LTE main antenna connector
Signal strength indication LEDs
3.2. Hardware installation
1. Remove back panel and insert SIM card which was given by your ISP (Internet
Service Provider). Correct SIM card orientation is shown in the picture.
2. Attach LTE main and Wi-Fi antennas.
3. Connect the power adapter to the socket on the front panel of the device. Then plug
the other end of the power adapter into a wall outlet or power strip.
4. Connect to the device wirelessly using the SSID: Case6904 ) or use Ethernet cable and
plug it into any LAN Ethernet port.
6904 3G/4G LTE Router Manual
3.3. Logging in
After you’re complete with the setting up as described in the section above, you are ready to
start logging into your router and start configuring it. This example shows how to connect on
Windows 7. On windows Vista: click Start -> Control Panel -> Network and Sharing Centre ->
Manage network Connections -> (Go to step 4). On Windows XP: Click Start -> Settings ->
Network Connections -> (see step 4). You wont’s see “Internet protocol version 4(TCP/IPv4)”,
instead you’ll have to select “TCP/IP Settings” and click options -> (Go to step 6)
We first must set up our network card so that it could properly communicate with the router.
1. Press the start button
2. Type in “network connections”, wait for the
results to pop up.
3.Click “View Network Connections
4. The right click on your wireless device that you use to
connect to other access points (It is the one with the
name “Wireless Network Connections” and has signal
bars on its icon)
6904 3G/4G LTE Router Manual
7. If you choose to configure manually here’s what you do:
First select an IP address.
The routers factory settings allow you to enter an IP address in the form of 192.168.1.XXX ,
where XXX is a number in the range of 2-254 (192.168.1.2 , 192.168.1.254 , 192.168.1.155 and
so on… are valid; 192.168.1.0 , 192.168.1.1 , 192.168.1.255 , 192.168.1.699 and so on… are
not).
Next enter the subnet mask: this has to be “255.255.255.0”. Then we enter the default gateway:
this has to be “192.168.1.1”. Finally we enter primary and secondary DNS server IPs. One will
suffice, though it is good to have a secondary one as well as it will act as a backup if the first
should fail. The DNS can be your routers IP (192.168.1.1), but it can also be some external
DNS server (like the one Google provides: 8.8.8.8).
5. Select Internet Protocol Version 4
(TCP/IPv4) and then click Properties.
6. By default the router is going to have DHCP
enabled, which means that if you select “Obtain
an IP address automatically” and “Obtain DNS
server address automatically”, the router should
lease you an IP and you should be ready to
login.
6904 3G/4G LTE Router Manual
Right click on the Wireless network icon and select Connect / Disconnect. A list should
pop up with all available wireless networks. Select “Case6904” and click connect. Then
we launch our favourite browser and enter the routers IP into the address field:
Press enter. If there are no problems you should be greeted with a login screen such as this:
Enter the default username, which is “root” into the user name field and enter ‘case’ into the
Password field and then either click Login with your mouse or press the Enter key. You have
now successfully logged into the CASE6904!
From here on out you can configure most parts of your 6904 router.
6904 3G/4G LTE Router Manual
4. Operating Modes
The CASE6904 series router supports various operation modes. It can be connected to the
internet (WAN) via mobile, standard Ethernet cable or via a wireless network. When
connecting to the internet, you may also backup your main WAN connection with one or two
backup connections. Any interface can act like backup if configured so. At first router uses its
main WAN connection, if it is lost then router tries to connect via backup with higher priority
and if that fails too, router tries the second backup option.
In later sections it will be explained, in detail, how to configure your router to work in a
desired mode.
6904 3G/4G LTE Router Manual
5. Powering Options
The CASE6xx router can be powered from power socket or over Ethernet port. Depending on
your network architecture you can use LAN 1 port to power the device.
The CASE 6904 can be powered from power socket and over Ethernet simultaneously. Power
socket has higher priority meaning that the device will draw power from power socket as long
as it is available.
When the CASE 6904 is switching from one power source to the other it loses power for a
fraction of the second and may reboot. The device will function correctly after the reboot.
Though the device can be powered over Ethernet port it is not compliant with IEEE 802.3af2003 standard. Powering CASE6309 from IEEE 802.3af-2003 power supply will damage the
device as it is not rated for input PoE Standard voltages.
5.1 Powering the device from higher voltage
If you decide not to use our standard 9 VDC wall adapters and want to power the device from
higher voltage (15 – 30 VDC) please make sure that you choose power supply of high quality.
Some power supplies can produce voltage peaks significantly higher than the declared output
voltage, especially during connecting and disconnecting them.
While the device is designed to accept input voltage of up to 30 VDC peaks from high voltage
power supplies can harm the device. If you want to use high voltage power supplies it is
recommended to also use additional safety equipment to suppress voltage peaks from power
supply. One of the options is to use “Case Communications” over-voltage protection device
conforming ISO 7637-2
