My PWR LED is not lit.
Solution 1:
The PWR LED does not light until the drivers are installed. Make sure
that the drivers are installed correctly by following the general trouble-
shooting procedure above.
Solution 2:
When you insert or remove a USB cable from your computer, the compu-
ter should indicate activity such as hard disk activity or an hourglass cur-
sor. If the computer does not show any sign of activity, your system may
not be properly communicating with the USB ports. Try these techniques
to determine whether the ports are communicating properly:
1. Try using a different USB port on the computer. If you are using a
USB hub, try using a USB port on the computer instead.
2. If the modem has worked previously and you removed the USB cable
from the computer and then reconnected it, try another USB port.
The modem may have been installed originally on the other USB port.
3. Windows Users: Your USB port may not be enabled. To ensure that
USB is enabled on your system:
A. Go to the device manager:
Windows Vista:
1) Click Windows Start >Control Panel >System and Main-
tenance >System.
2) Under Tasks, click Device Manager.
Windows XP:
1) Click Windows Start >Control Panel.
2) Double-click System.
3) On the Hardware tab, select Device Manager.
Windows 2000:
1) On the desktop, right-click My Computer and select Proper-
ties.
2) On the Hardware tab, click Device Manager.

English
11
Windows Me or 98:
1) On the desktop, right-click My Computer and select Proper-
ties.
2) Select the Device Manager tab.
B. Look for an entry for USB controllers.
If the device manager does not have an entry for USB controllers,
you must enable USB in the computer’s BIOS. For instructions,
check with your computer manufacturer's technical support. Once
your USB port has been enabled in your system's BIOS, Windows
will automatically detect and install USB support when you restart
your computer.
My communication software does not recognize the
modem.
Solution 1:
Your communication software may not function properly if any of the
following are true:
!More than one version of the software is installed on your computer.
!You are using an old version of the software.
!More than one communication software package is installed on your
computer.
USRobotics highly recommends using the communication software pro-
vided with the modem on the USRobotics Installation CD-ROM.
Solution 2:
Your communication software may be selecting the wrong modem type.
For instructions on adjusting the modem settings in your software, refer
to your communication software’s documentation.
Solution 3:
Windows Dial-Up Networking Users: Make sure that your Windows
Dial-Up Networking connection is using the correct modem.

Windows Vista:
1. Click Windows Start >Control Panel >Network and Internet
>Network and Sharing Center >Manage network connec-
tions.
2. Right-click the description of the dial-up networking connection,
and select Properties.
3. Make sure that your new modem is selected.
Windows XP:
1. Click Windows Start >Control Panel, and double-click Net-
work Connections.
2. Double-click the description of the dial-up networking connec-
tion, and select Properties.
3. Make sure that your new modem is selected.
Windows 2000:
1. Click Windows Start >Settings >Network and Dial-up Con-
nections.

tion, and select Properties.
3. Make sure that your new modem is selected.
My modem doesn’t dial out or answer incoming calls.
You may have a bad telephone cord. Try another telephone cord.
Solution 4:
You may have plugged the modem’s phone cord into a digital line. Con-
tact the department responsible for your phone system if you are unsure
whether your phone line is analogue or digital.
Solution 5:
If your phone system requires an access code to access an outside line, be
sure to include the code in the number that you are dialling.

English
13
Solution 6:
If your voice mail alters your dial tone when messages are waiting, restore
the normal dial tone by retrieving your messages before using the modem
to dial out.
My modem tries to connect to another modem, but the
connection fails.
You may have a poor connection. Try placing the call again.
My modem or computer is performing erratically.
Solution:
Some USB host controllers have power output issues which may cause
erratic performance for any USB device or the computer itself when any
USB device is in use. Try using a powered USB hub or check with the
manufacturer of your USB host controller for a possible driver update.
My modem is not achieving a 56K Internet connection.*
Solution 1:
Contact your ISP to verify that the number you are dialling supports
V.90/V.92 speeds.
Solution 2:
Contact your telephone company to verify that the telephone line for
your modem supports V.90/V.92 speeds.
* Capable of receiving at up to 56 Kbps and sending at up to 48 Kbps (or 31.2 Kbps with
V.90 server). Due to FCC regulations on power output, receiving speeds are limited to
53.3 Kbps. Actual speeds may vary. V.92 and V.90 features require compatible phone
line and support from your Internet Service Provider (ISP). USRobotics modems fea-
turing V.92 enhancements are backward compatible and will negotiate the highest pos-
sible speed when connecting to an ISP. Typical receive speeds range from 40 Kbps to
53 Kbps.

14
English
Solution 3:
Line interference or the routing of the telephone call to your ISP may be
causing a slower connection speed. Try placing the call again.
Solution 4:
Verify that the modem is connecting to a V.90/V.92 server. A pair of 56K
modems will not connect to each other at 56K speeds.
