Q.
I need to modify the settings on the WRP400.
To access the web-based utility, follow these instructions:
a.
Launch the web browser on your computer, and enter the default IP
address of the WRP400, 192.168.15.1, in the
Address
field. Then press
Enter.
NOTE
If you place the WRP400 behind a primary router with the IP address
of 192.168.15.1, then the WRP400 will automatically assume a new
default IP address, 192.168.16.1.
b.
A login screen appears. The first time you open the web-based utility,
use the default user name and password,
a
dmin. (You can set a new
password from the Administration tab’s Management screen.) Then click
OK.
c.
Click the appropriate tab to change the settings.
Q.
I cannot configure the settings for the second wireless network
because the SSID2 settings are grayed out.
Your service provider may control the settings for the second wireless
network (SSID2). Contact your service provider for more information.
Q.
I upgraded my firmware and now the WRP400 is not working properly.
If the WRP400 is not working properly after an upgrade, you may need to
perform a factory reset. There are two ways to perform a factory reset.
-
Option 1: Press and hold the reset button located on the side panel for
approximately ten seconds.
-
Option 2: Access the web-based utility and browse to
Administration >
Factory Defaults
. Select
Yes
to reset the WRP400 settings to the
default values.
NOTE
Service Providers: If version 2.0 or higher is installed, and you want to
downgrade a device to version 1.0, first downgrade to version 1.01.00.
Then downgrade to version 1.0. This interim firmware is designed to
ensure that the version 2.0 settings are reconfigured for version 1.0.

Mobile Network Troubleshooting
Q.
What do I do if the WRP400 does not recognize my USB device?
a.
Make sure that you have the latest mobile-support firmware loaded on
your WRP400. To download the latest firmware, go to the WRP400
product page on
www.cisco.com/en/US/products/ps10028/index.html
b.
Make sure that your USB device is on the list of supported Mobile
Broadband USB Modems. For more information, visit the WRP400
product page on
www.cisco.com/en/US/products/ps10028/index.html
c.
If you're installing a Mobile Broadband USB modem, make sure that your
modem is activated with a data service, and verify that it can be used on
your computer.
Q.
The Power LED is continuously flashing green and orange. What does it
mean?
When you plug in a USB device, the Power LED indicates the progress of
initialization. After successful initialization, the Power LED shines steady
green.
If the device fails to initialize, the LED continues to flash green and orange. In
this case, check to make sure that you have the latest firmware, that your
USB device is supported, and that your modem is activated with a data
service, as described above.
Q.
My WRP400's Power LED continuous flashing orange. What does it
mean?
When a USB modem is installed, the Power LED indicates the status of the
mobile network connection. Continuous flashing orange means the router
failed to connect to the Internet through the mobile network connection and
is trying again. One possible explanation is that the router cannot get a
strong signal from the mobile network. Consider moving the router to a
location where you have a stronger signal. The Power LED shines steady
orange upon a successful mobile network connection,

Q. I am unable to connect to the mobile network. What do I do?

Make sure that you have the latest mobile-support firmware loaded on
your WRP400. To download the latest firmware, go to the WRP400
product page on
www.cisco.com/en/US/products/ps10028/index.html

c.
If you're installing a Mobile Broadband USB modem, make sure that your

your computer.
d.
Some mobile network service providers require that you enter specific
information such as APN, Dial Number, User Name, and Password. This
information can be obtained from your service provider, if required. Log
on to the WRP400 administration web server and input the correct
settings on the Setup > Mobile Network page, the Mobile Network Setup
section.
e.
Make sure that you input the correct SIM PIN if you lock your SIM with a
PIN code.
Q.
How do I disconnect from the mobile broadband network, when not in
use?
Disconnecting from your mobile broadband service when not in use may
provide savings on usage costs or prevent unnecessary downloads.
To
disconnect, you can use one of the following methods:
-
Option 1: Physically remove and reinsert your Mobile Broadband USB
modem from the WRP400.
-
Option 2: Log on to the WRP400 web-based utility. Click Setup tab >
Mobile Network page. Click the
Disconnect
button.
NOTE
The Disconnect button appears only when Connect mode is set on
Manual. For more information, see
“Setup > Connection Recovery,”
on page 46
.
Q.
Why does my WRP400 always use my Ethernet connection instead of
my mobile network connection?
By default, the WRP400 connects to the Internet through the Ethernet
interface, if available. The mobile network connection may be used as a
failover when an Ethernet connection is unavailable. If you wish to connect
to mobile network only, simply unplug your Ethernet cable. Alternatively,
change the Priority setting so that the mobile network connection is used
even when the Ethernet cable is connected. To change these settings, log

on to the WRP400 web-based utility and use the Setup tab > Mobile
Network page and the Setup tab > Ethernet Recovery page. For more
information, see
“Setup > Mobile Network,” on page 43
and
“Setup >
Connection Recovery,” on page 46
.
Q.
How do you know which mobile network you are using?
Follow these instructions:
a.
Open a web browser.
b.
Enter the IP address of the WRP400 in the Address field (the default IP
address is 192.168.15.1). Then press
Enter
.
c.
When prompted, complete the User name and Password fields (the
default user name and password is
admin
). Click
OK
.
d.
Click the
Status
tab.
e.
Click the
Mobile Network
tab. In the Mobile Network Status section, on
the Carrier line, you will see the name of the network that you are
currently using.
Q.
Can I make a VoIP call over the mobile broadband network?
If the WRP400 is configured to use a Mobile Broadband USB modem and
voice services with an Internet telephony service provider, the WRP400 can
send and receive voice traffic over the mobile broadband network.
However, because a voice service is more sensitive to latency and network
congestion compared to data services, your voice quality over the mobile
network cannot be guaranteed.
Q.
What if my Mobile Broadband USB modem is not supported on the
WRP400?
Cisco is continuously adding support for more Mobile Broadband USB
modems and works closely with mobile broadband providers and
manufacturers to stay current with the latest devices available. For a current
list of supported Mobile Broadband USB Modems, visit the WRP400
product page at www.cisco.com/en/US/products/ps10028/index.html
