I password protected my SureConnection lock and I don’t remember my 
password.
You will need to uninstall the SureConnect Utility and reinstall it in order to 
deactivate the password. Once you reinstall the SureConnect Utility, there 
will be no password activated. Refer to the uninstallation instructions 
located on the Installation CD-ROM or by clicking the Help button in the 
SureConnect Utility. 
When I complete my installation, the Test tab of the U.S. Robotics SureConnect 
ADSL Utility displays and states that the modem test failed but I can still surf the 
Internet.
If you have a router between the modem and the computer, this version of 
SureConnect will not detect the modem. In order for SureConnect to detect 
the modem and display its status, the modem must be connected directly 
to the computer. The modem will still function properly; however, the 
SureConnect Utility cannot be used. You may safely delete the SureConnect 
Utility shortcut from your Startup folder or use Add/Remove Programs to 
uninstall the SureConnect Utility. 
The modem installed properly, the “PWR” LED is on, the phone line is connected, 
but the “ADSL” LED is off or keeps flashing.
• Review the Troubleshooting Checklist at the beginning of this section. 
• Go to the U.S. Robotics SureConnect ADSL Utility Monitor tab and 
press the Reset button once. The modem will re-establish the 
connection; this may take a moment. 
• Open the U.S. Robotics SureConnect ADSL Utility by clicking the icon 
on the task bar. Go to the Test tab and run a test on the modem in 
order to identify the cause of the failure.
•Call your ISP.
Macintosh and Linux
I installed the modem on a Macintosh and I need to connect using PPP, but the 
only choice I have for connecting in the Modem configuration is “Internal 
Modem.”
Most likely, your modem is not properly installed. 
I installed the modem on a Macintosh and have followed the instructions for 
installing the software and the hardware; however, when I plug the modem in, 
nothing happens.
• This could be one of a number of things. First, try to run the Uninstall 
script. If you are using ADSL Annex A, which works over a standard 
telephone line, double-click USRxx9002 (POTS) ADSL Modem. If you 
are using ADSL Annex B, which works over an ISDN line, double-click 
USR029002 (ISDN) ADSL Modem.

• Your corresponding window will display. Select Uninstall and click 
the Uninstall button located in the lower-right corner of the screen.
• Once the modem is uninstalled, remove the cables and restart the 
installation process from the beginning. If that does not work, you 
should contact your ISP.
I installed the modem on a Macintosh and want to make sure that I’m getting the 
throughput that I should expect from this ADSL connection. How can I get this 
information?
Open the USR ADSL Modem from the desktop and click the Statistics tab. 
This will display information such as: how much data is being transmitted, 
how many errors have been encountered, and the line speed at which you 
are connected.
How can I verify my modem's installation on a Macintosh?
Before proceeding with Configuration, you should verify that your modem 
has been successfully identified by the operating system and that the 
modem has successfully connected to your ADSL provider.
1. Go to the Desktop and double-click the USR ADSL Modem icon.
2. Go to the Operation page of the U.S. Robotics Monitor screen. If the 
screen shows ADSL / Modem status as "Modem is operational," then 
the modem has been successfully identified by the operating system 
and has connected to the DSLAM (Digital Subscriber Line Access 
Multiplexer) in the Central Office (CO). 
How do I uninstall the modem on a Macintosh?
1. If you are using ADSL Annex A, which works over a standard telephone 
line, double-click USRxx9002 (POTS) ADSL Modem. If you are using 
ADSL Annex B, which works over an ISDN line, double-click 
USR029002 (ISDN) ADSL Modem.
2. Your corresponding window will display. Select the Uninstall option 
and click the Uninstall button located in the lower-right corner of the 
screen.
3. Once the modem is uninstalled, remove the cables.
How do I disable the modem driver on a Linux system?
Unplug the USB cable from the computer and run the following command to 
remove the driver.

While trying to surf the Internet, I received a “Page Not Found” or similar error.
Your computer may not have acquired an IP address from your provider’s 
DHCP server when you established the connection. Disconnect your dial-up 
connection, and then reconnect it to force a new request. If you are still 
receiving an error, restart the computer. 
The ADSL LED is flashing or is not illuminated.
Make sure that the RJ-11 cable is properly connected in the “ADSL” port on 
the rear of the modem and in the phone wall jack in your home. The “ADSL” 
LED on the front of the modem should be illuminated.
