Troubleshooting
Having trouble with your modem? Try
these basic troubleshooting steps first!
1.
Make sure that your phone cord is properly connected. Remove the
phone cord from the modem and wall jacks. Clean any dirt or corro-
sion from the cord and jacks. Reinsert the cord securely in the wall
jack and the modem's
jack. Use the phone cord included with
TELCO
your modem, if possible.
2.
Make sure that your modem is turned on. The Power light on the
front panel will be on when your modem is on.
3.
Make sure your power supply is connected properly to both your
modem and an electrical outlet. If it is, check the outlet with another
electric device (like a lamp) to be sure that you are getting power.
Also, use the power supply that came with your modem; other simi-
lar-looking power supplies may be of different voltages and could
damage your modem.
4.
Make sure that you are using the proper cable. If you are using your
modem as a USB device, you will to need to purchase a USB A to B
cable. If you are using your modem as a serial device, you will need
to purchase an RS-232 serial/modem cable. Check the packaging of
the cable you bought. There are many computer cables that look
similar to an RS-232, such as a Null Modem cable, that will not work
correctly with this modem. Depending on whether you have a 9-pin
or 25-pin serial port on your computer, you will need either a DB9/
DB25 or a DB25/DB25 serial cable. See the diagrams below.
Use a DB25F to DB25M
Use a DB9F to DB25M
RS-232 serial cable
RS-232 serial cable
Use a USB A to B cable
Note:
You should NOT attempt to connect or use your modem with
both the USB and serial cable connected at the same time. Your
modem may fail to respond. If this occurs, you must turn off your
computer, disconnect the cable you are not using, and restart your
system.
PROBLEM:
My computer isn't recognizing my modem.
Possible solution:
Make sure the modem is plugged in and turned on. If it is, check the outlet with
another electric device (like a lamp) to be sure that you are getting power. Also, you
must use the power supply that came with your modem; other similar-looking
power supplies may be of different voltages and could damage your modem.
When your modem is properly connected to power and is turned on, the power
light on the front panel will be on.
Possible solution:
Make sure you are using the proper cable. This modem requires an RS-232 serial
cable or a USB cable. Check the packaging of the cable you bought. There are
many computer cables that look similar to an RS-232 or a USB cable, such as a
Null Modem cable, that will not work correctly with this modem.
Possible solution:
You may be using a COM port that is either already in use or not configured
correctly. To work properly when a serial connection is being used, this modem
needs to be plugged into an enabled serial port that is assigned to a free COM
port. Typically, most computers have two serial ports assigned to COM 1 & 2
respectively.
Windows 2000 Users:
Make sure your COM port is not already in use by another
modem. Click Windows Start, Settings, and Control Panel, and then double-
click Phone and Modem Options. Click the Modems tab. Look for another
modem already in the machine. If there is another modem listed, check which
COM port it is using. If a previous modem is already using the available COM
port, you can either use another COM port or uninstall the previously installed
modem. See your previous modem's manual for the instructions to uninstall
that modem.
Next make sure that your COM Ports are configured correctly. Right-click the My
Computer icon on your desktop. Click Properties. Click the Hardware tab. In
the "Device Manager" section, click the Device Manager button. Look under
Ports (COM & LPT). If the COM Ports have yellow exclamation points or red Xs
over them, your COM ports may be configured incorrectly. If this is the case, you
may need to contact your computer manufacturer.
It is also possible that you may be plugging an external modem's cable into
a disabled serial port. Refer to your computer's manual for information about
enabling COM ports. This usually involves altering the BIOS settings and
possibly the operating system. You may need to call your computer's
manufacturer to change your BIOS settings if they are incorrect.
Windows 95/98 Users:
Make sure your COM port is not already in use by
another device. Click Windows Start, Settings, and Control Panel, and then
double-click Modems. Look for another modem already installed in your com-
puter. If there is another modem installed, click the Diagnostics tab to find out
which COM port it is using. If a previously installed modem is already using the
available COM port, you should uninstall that modem. See your previous
modem's manual for the instructions to uninstall that modem.
Right-click the My Computer icon on your desktop. Click Properties. Click the
Device Manager tab. Double-click Ports. If the Communications Ports have
yellow exclamation points or red Xs over them, your COM ports may be config-
ured incorrectly. If this is the case, you may need to contact your computer
manufacturer.
Windows NT Users:
Turn off your computer and remove your modem. Restart
and click Windows Start, Settings, and then Control Panel. Double-click the
Ports icon. Your modem must be set to a COM port setting that does not appear
in this list.
PROBLEM:
My software isn't recognizing my modem.
Possible solution:
Your communications software may not function properly if you have more than
one version of the software installed, you are using an older version, or you
have more than one communications application installed on your system. We
highly recommend using the communications software provided with your
modem on the Connections
TM
CD-ROM.
Possible solution:
Make sure the modem is plugged in and turned on. If it is, check the outlet with
another electric device (like a lamp) to be sure that you are getting power. Also,
you must use the power supply that came with your modem; other similar-
looking power supplies may be of different voltages and could damage your
modem.
When your modem is properly connected to power and is turned on, the power
light on the front panel will be on.
Possible solution:
Your software's COM port settings may be incorrect. There should be a place in
the Setup section of your software that addresses port settings. Make sure the
software's port settings match those for your modem. To check which COM
port your modem is using, click Windows Start, Settings, and Control Panel.
Double-click Modems, select your modem, and click Properties.
Check your communication software's documentation for instructions on ad-
justing the port settings in your software.
Possible solution:
You may not have the correct modem type selected in your software or in
Windows.
Windows 2000 Users:
Click Windows Start, Settings, and Control Panel.
When Control Panel opens, click Phone and Modem Options. Click the
Modems tab.
Windows 95/98 Users:
Click Windows Start, Settings, and Control Panel.
When Control Panel opens, click Modems.
Here you will see a list of installed modems. You can also add, remove, or
view the properties of modems from this window. The U.S. Robotics modem
you have installed should be present in the list of installed modems. If none
of the modem descriptions in the list matches your U.S. Robotics modem or
no modems are listed, your modem is not properly installed. Try reinstalling
your modem.
Possible solution:
If you are using Dial-Up Networking, it may not be configured correctly. Check
your configuration and make sure you have the correct modem selected.
Windows 2000 Users:
Click Start, point to Settings and click Network and Dial-
up Connections. Make sure that the description in the modem box matches
the description of the modem you are using. If it doesn't match, select the
proper modem description.
Windows 95/98 Users:
Double-click My Computer, double-click Dial-Up Net-
working, right-click the connection you are trying to use, and click Properties.
Make sure that the description in the modem box matches the description of
the modem you are using. If it doesn't match, select the proper modem de-
scription.
PROBLEM:
My modem won't dial out or doesn't answer incom-
ing calls.
FOR BOTH DIALING AND ANSWERING PROBLEMS:
Possible solution:
Make sure that you are using the power supply that came with your modem;
other similar-looking power supplies may be of different voltages and could
damage your modem.
Possible solution:
You may have a bad phone cord connection to your modem, or your phone
cord may be plugged into the wrong jack. The phone cord should be plugged
into the
jack on the modem and into the wall phone jack. Use the
TELCO
phone cord included in your modem's box if possible.
Possible solution:
You may have devices between the modem and the phone jack. There
should be no line splitters, fax machines, or other devices between
the modem and the wall jack.
OFFICE AND HOME USERS:
Possible solution:
You may have plugged your modem's phone cord into a digital line.
Contact the department or agency responsible for your phone sys-
tem if you are unsure whether or not your phone line is digital.
If your phone system requires dialing "9" to access an outside line,
be sure to add "9" before the number you are dialing.
VOICE MAIL USERS:
Possible solution:
If you have voice mail provided by your local phone company, your dial
tone may be altered when messages are waiting. Retrieve your voice
mail to restore your normal dial tone.
PROBLEM:
My modem sounds like it's trying to connect
to another modem but fails.
Possible solution:
You may have a poor connection. All calls are routed differently,
so try placing the call again.
PROBLEM:
My modem isn't achieving a 56K Internet con-
nection.
Our research has shown that the vast majority of telephone lines in
North America can and do support V.90/V.92 connections. The V.90/
V.92 protocol allows for connection speeds of up to 56K, but line
conditions may affect the actual speeds during a given connection.
Due to unusual telephone line configurations, some users will not
be able to take full advantage of V.90/V.92 technology at this time. In
order to achieve a V.90/V.92 connection:
· The server you're dialing into must support and provide a digital
V.90/V.92 signal. Your ISP can provide you with a list of dial-up
connections and information on what those connections currently
support.
· The telephone line between your ISP and your modem must be
capable of supporting a 56K connection and contain only one
analog-to-digital conversion. The 56K signal from your ISP begins
as a digital signal. Somewhere between the ISP and your modem,
there will be a digital-to-analog signal conversion so that your
modem can receive the data. There must be no more than one
analog-to-digital signal conversion in the path from your ISP to your
modem. If more than one analog-to-digital conversion occurs, your
connect speeds will default to V.34 (33.6 Kbps). There may also be
impairments on the local lines between your ISP and your modem.
These impairments can prevent or limit connection speeds. All
telephone calls are routed differently, so you should try making your
56K connection several times. One way to test this is to dial into a
long distance location. Long distance lines are often much clearer
than local lines. It is important to note that telephone companies
are constantly upgrading their systems. Lines that do not support
56K today may support 56K in the near future.
· For a V.90 connection, your modem must be connecting to a V.90/
56K server. A pair of 56K modems will not connect to each other at
V.90/56K speeds.
· For a V.92 connection, your modem must be connecting to a V.92
server or a receiving modem with a digital connection, such as an
ISDN modem or a modem with a T1 connection.
Note:
Current IC/FCC regulations limiting power may limit maximum
download speeds to 53,333 bps.
