2 Installation
Attention:
After the B890 is installed, keep it upright, so the indicators are easy to see.
Furthermore, when placed flat, the B890 may be damaged due to poor heat
dissipation.
Only use a B890-compatible power adapter. Using an incompatible power
adapter may cause damage to the B890.
Note:
When connecting the B890 to a telephone, use an RJ11 telephone cable. Do not
connect the B890 to the telephone wall outlet (or any Public Switched Telephone
Network), because doing so could damage the B890 due to excessive heat.
Radio signals can interfere with telephone call connection and quality. To
eliminate interference, place the telephone at least 1 meter (3.28 feet) away from
the B890.
When connecting the B890 to a computer, use an RJ45 Ethernet cable no longer
than 100 meters (328 feet).
Scenario 1: Using the WAN Interface
Connect the cables in the sequence indicated in the following figure. Connect
cable to the B890's WAN port and the Ethernet port on the wall.
Once connected to a power supply, the B890 automatically powers on.

Advanced Scenarios: Using More Features
1. Installing an External Antenna
Skip this section if you do not need to connect an external antenna to the B890.
In areas with poor network coverage, connect an external antenna to the B890's
external antenna port for better signal reception.
Step 1 Remove the cover from the antenna port. (Keep it in a safe place.)
Step 2 Screw external antenna fully into the antenna port, as shown in the
following figure.
Note:
Before using an external antenna, log in to the web management page
(http://192.168.1.1) and set antenna mode to outer. For details, see the
help information on the web management page.
Only use the external antenna indoors, and do not use it during
thunderstorm.
2. Connecting to a USB device
Skip this section if you do not need to connect a USB device to the B890.
Connect a USB device to the B890, as shown in the following figure. For details,
see the help information on the web management page.
Note:
Do not connect a computer to the B890's USB port.
B890's USB port can supply a maximum current of 500 mA. If the current
required by a peripheral device, such as a portable hard disk drive, connected to
the B890 is higher than 500 mA, the B890 may fail to recognize the device. In
this case, use an auxiliary power supply for the peripheral device. For more
information, contact your service provider.

3 Setting Up a Wireless Connection
Note:
Before setting up a Wi-Fi connection, ensure that a wireless network adapter has
been installed on your computer. If the wireless network adapter is functioning
correctly, you will be able to find a wireless network connection in your computer's
connection manager application.
Turning the Wi-Fi On
The B890's Wi-Fi automatically turns on when
the B890 is powered on.
To manually turn Wi-Fi off, press and hold
the button for 2 seconds. The
indicator turns off.
To manually turn Wi-Fi on, press and hold
the button until the indicator
turns steady on.
Setting Up a Wi-Fi Connection Manually
A computer running Windows 7 is used as an example to describe how to
manually set up a wireless connection:
Step 1 Ensure that the indicator is steady on, and the wireless
configuration service of the computer that you want to connect is
enabled.
Step 2 Find and make note of the wireless network (SSID) and password
(Wi-Fi Key) printed on the label on the rear panel of the B890.
Step 3 Configure the wireless network connection on the computer as follows:
1. Choose Start > Control Panel > Network and Sharing Center >
Change Adapter settings.
2. In the Network Connections window, right-click the Wireless
Network Connection to display a shortcut menu, and select
Connect/Disconnect.
3. In the Wireless Network Connection dialog box, select the wireless
network whose name is the same as the one you recorded in Step 2,
and click Connect.
4. In the Connect to Network dialog box, enter the wireless network
password you recorded in Step 2, and click OK.

10
After the system verifies the password, Connected appears on
the wireless network icon in the wireless network list, indicating that
your computer has established a wireless connection to the B890.
Note:
If the wireless network name (SSID) and password (Wi-Fi Key) are changed, the
information will have to be reconfigured on your computer.
To protect your wireless network from unauthorized access, change the SSID
and Wi-Fi key a regular intervals. For details, see the help information on
the web management page.
Setting Up a Wi-Fi Connection Automatically
If the client to which the B890 connects supports WPS, a Wi-Fi key is generated
automatically.
To set up a WPS connection:
Step 1 Ensure that the indicator is steady on, and the wireless
configuration service of the computer that you want to connect is
enabled.
Step 2 Press and hold the button until the indicator blinks to
activate the WPS connection on your device.
Step 3 Activate the WPS connection on the client.
Note:
For details about operations on the client side, see the client user guide.

5 Accessing the Internet
The B890 can access the Internet through wireless networks (3G/4G networks)
and wireline networks (Ethernet networks), but it cannot access both networks
simultaneously.
Accessing a 3G/4G Wireless Network
If the USIM card is correctly installed, the B890 automatically searches for
networks after startup.
If the B890 is connected to a 3G/4G network, the indicator turns steady on.
You can then access the Internet through the 3G/4G network.
Note:
If the B890 fails to connect to the network, log in to the web management page to
verify the wireless network parameters. For details, see the help information on
the web management page.
Accessing an Ethernet Network
If the B890 is connected to the Ethernet, it automatically connects to network.
Once the B890 connects to a network, the indicator turns steady on. You
can then access the Internet through the Ethernet network.
Note:
If the B890 fails to connect to the network, log in to the web management page to
verify the wireline network parameters. For details, see the help information on
the web management page.
Accessing the Internet Manually
The B890 can access the Internet in Auto, Manual, or
On Demand mode. To manually connect to or
disconnect from the Internet, press the button.
When the B890 is connected to the Internet, the
or indicator lights up.

press and hold the RESET button until the signal indicators on the bottom blink.
Note:
After the factory defaults are restored, the B890 automatically restarts.
Restoring the factory defaults will delete all settings defined by the user and
restore all settings on the web management page to their defaults.
7 Troubleshooting Tips
