A list will display all interfaces on your system. Locate the ADIModem interface.
Once the interface is located, you can configure it using either one of the
following methods:
•
DHCP
•
Static IP Address
Configure Interface Using DHCP
1.
Confirm that your server provides a DHCP server.
2.
If it does, then run the following script:
USR_USB/ADI_PPPOE/./godhcp
3.
To confirm the interface is operational and it has an IP address assigned,
run the following script:
ifconfig
Configure Interface Using a Static IP Address
1.
Run the following script to configure the interface using a Static IP
Address:
USR_USB/ADI_PPPOE/./gostatic ADIModem IPAddress Netmask
route add default gw ipaddress (this is the gateway provided by your
ISP)
pico/etc/resolv.conf
namesaver ipaddress (insert your DNS Address as provided by your
ISP)
2.
Run the following command to confirm the interface is operational and an
IP address has been assigned:
ifconfig
Once the interface is properly configured, you can start sending and receiving
data.
Whenever you unplug the USB cable, you need to run one of
the above scripts. If you want to bring down the interface and
bring it back up, run the USR_USB/ADI_PPPOE/./stopip. Use
one of the above script files to configure the interface again.

8.
To disconnect from the server, run ADI_PPP_Stop at the same directory
and PPP will disconnect from the server.
The graphic below shows the U.S. Robotics SureConnect ADSL USB/Ethernet
Modem connected to an ISP. The ADIModem interface is loaded (local IP
192.168.60.30), and the ppp0 interface is up and running with an IP address
(80.11.157.151) and a gateway (80.11.157.1).
Modem Status
To view various statistics about the modem and the connection, run the
following script:
USR_USB/ADI_PPPOE/./showstat
The statistical information will be available through ADIModem in /proc
directory.
This feature is available as soon as you plug the USB cable in.

PPPoA Interface
1.
After you have built the driver, run the following script:
USR_USB/./inst_pppoa
2.
The script will compile, build, and install the PPPoA module. Upon comple-
tion, the script will copy the needed scripts and configuration files into the
/usr/sbin and /etc/ppp directories.
3.
If you are using ADSL Annex A, confirm that the VPI/VCI and Encapsulation
type parameters located in the /etc/analog/usradslpots.conf are the
same as the ones provided to you by your ISP. If you are using ADSL Annex
B, which works over an ISDN line, confirm that the VPI/VCI and Encapsula-
tion type parameters located in the /etc/analog/usradslisdn.conf are the
same as the ones provided to you by your ISP.
4.
Plug the USB cable into the modem and computer.
5.
Modify the user name and password in pap-secrets, chap-secrets, and
options files in /etc/ppp directory with the values provided by your ISP.
For example, the format of the pap_secrets and chap_secrets files:
*Secrets for authentication using CHAP
*Client
server
secret
ISP username *
ISP password
In the Options file, you need to change the user "**********" with the
username provided by your ISP.
6.
Go into /usr/sbin directory and run the following script:
ADI_PPP_Go
7.
Once the script has completed, run ifconfig and confirm that you are con-
nected to your provider. PPP will create an interface called "ppp0" when-
ever it connects to a server.

Troubleshooting
Troubleshooting Checklist
To help diagnose the problem, use the checklist below.
Confirm that you have secured the power adapter to the modem and
to an active wall outlet. The "PWR" LED should be illuminated.
Confirm that you have secured the telephone cable to the telephone
jack and to the modem. The "ADSL" LED should be illuminated.
If you connected using a USB cable, confirm that you have secured the
USB cable to the "USB" port on the back of the modem and to the
"USB port on your computer. If you connected using an Ethernet
cable, confirm that you have secured the Ethernet cable to the "ENET"
port on the modem and to the "ENET" port on your computer. The
"ENET" or the "USB" LED should be illuminated.
Have you contacted your Internet Service Provider to order ADSL ser-
vice to your home? If you have yet to contact your ISP, you must do
so, as the modem will be inoperable without acquiring proper service
from an ISP.
Verify that you are installing your ADSL equipment AFTER the "Service
Completion Date" given to you when you ordered your ADSL Internet
Service. If you have yet to contact your ISP, you must do so, as the
modem will be inoperable without acquiring proper service from an
ISP.
Confirm that you do not have a microfilter installed on the RJ-11 cable
that connects your modem to the telephone wall jack. If you do,
remove it.
If you were given software by your ISP to install, you need to install it.
If your ISP did not give you any software to install, you will need to
connect using the dial-up connection on the desktop.
(For Windows Users Only) Run a test using the U.S. Robotics Sure-
Connect ADSL Utility to identify any possible problems. For more
information about how to run a test, refer to the "U.S. Robotics Sure-
Connect ADSL Utility" section of this Quick Installation Guide.
Status LEDs
The U.S. Robotics SureConnect ADSL USB/Ethernet Modem has four LEDs on the
front of the modem. The first from the left is the "PWR" LED, the second is the
data transfer "ENET" LED, the third is the "USB," and the last is the "ADSL" LED.
The operational status of the modem is indicated by the LED conditions listed
below.
