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 corrosion from the
cord and jacks. Reinsert the cord securely in the wall jack and the modem’s
jack. Use the phone cord included with your modem, if possible.
2.
Make sure that your internal modem is physically installed correctly in
your computer. You will need to press the modem in firmly so that it is
seated properly in its slot. When the modem is installed correctly, you will
no longer see any part of the black edge. See the front of this guide for
complete instructions. If your modem still does not work, with your computer
off, remove the modem and reinstall it in another slot if possible.
PROBLEM:
My computer isn’t recognizing my modem.
Possible solution:
You may be using an IRQ that is already in use. To work properly, your
modem needs to be assigned to a free IRQ.
Windows 2000
Windows 2000
Windows 2000
Windows 2000
Windows 2000
If you set your modem’s jumpers to Plug-and-Play mode, Windows
should locate a free IRQ, if one exists, for your use by your modem.
If Plug-and-Play fails to install the modem, you need to determine IRQ
availability. Right-click the My Computer icon on your desktop. Click
Properties, and then the Hardware tab. In the Device Manager section,
click Device Manager. From the View menu, select Resources by
type. Click Interrupt Request (IRQ). You will now see a listing of your
system’s IRQs and the devices to which they are assigned. If an IRQ is
not present in this list, it indicates that Windows is not currently using it
and the IRQ is considered available.
Locate your modem in the list of devices. If a yellow exclamation point
appears over the modem’s description, your modem is in conflict with
another device. Either your modem or the other device will have to be
reinstalled to another IRQ in order to resolve your conflict.
If a usable, free IRQ does not exist, you may need to remove, disable, or
relocate another device. Refer to that device’s documentation for more
information about removing, disabling, or relocating it.
If Windows still fails to recognize your modem and it does not have a
yellow exclamation point next to its IRQ, or if your modem doesn’t
appear in the list, another problem exists, and you may need to call
3Com Technical Support.
Windows 95/98
If Plug-and-Play fails to install the modem, you need to determine IRQ
availability. Right-click the My Computer icon on your desktop. Click
Properties, and then the Device Manager tab. Double-click the Computer
icon at the top of the device list. You will now see a listing of your system’s
IRQs and the devices to which they are assigned. If an IRQ is not present in
this list, it indicates that Windows is not currently using it, and the IRQ is
considered available.
Locate your modem in the list of devices. If a yellow exclamation point
appears over the modem’s description, your modem is in conflict with another
device. Either your modem or the other device will have to be reinstalled to
another IRQ in order to resolve your conflict.
If a usable, free IRQ does not exist, you may need to remove, disable, or
relocate another device. Refer to that device’s documentation for more
information about removing, disabling, or relocating it.
If Windows still fails to recognize your modem and it does not have a yellow
exclamation point next to its IRQ, or if your modem doesn’t appear in the
list, another problem exists, and you may need to call 3Com Technical
Support.
Windows NT
Turn off your computer and physically remove the modem. Restart your
computer, and check for an available IRQ by clicking Windows Start,
Programs, Administrative Tools, and Windows NT Diagnostics. Click
the Resources tab and select IRQ. Take note of an available IRQ that your
modem can use. If there are no IRQs available, you may have to remove,
disable, or relocate another device in order to free an IRQ for use by your
modem. Refer to that device’s documentation for more information about
removing, disabling, or relocating it.
Possible solution:
You may be using a COM port address that is either already in use or not
configured correctly. To work properly, this modem needs to be assigned to
a free COM port.
Windows 2000
Windows 2000
Windows 2000
Windows 2000
Windows 2000
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 uninstallation instructions.
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 Communications Ports have yellow exclamation points or
red Xs over them, your COM ports may be configured incor-
rectly. 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
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 computer. 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 uninstallation instructions.
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 configured incorrectly.
If this is the case, you may need to contact your computer
manufacturer.
Windows NT
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
Installation CD-ROM.
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 select Properties.
Check your communication software’s documentation for
instructions on adjusting the port settings in your software.
Possible solution:
You may not have the correct modem type selected in your software
or in Windows. Click on Windows Start, Settings, and Control
Panel. When Control Panel opens, click Modems. You will see
a list of installed modems. You can also add, remove, or view the
properties of modems from this window. The 3Com 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 match your
3Com U.S. Robotics modem or no modems are listed, your
modem is not installed properly. 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. Double-click My Computer, double-
click Dial-Up Networking, 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 description.
PROBLEM:
My modem won’t dial out or doesn’t answer
incoming calls.
FOR BOTH DIALING AND ANSWERING PROBLEMS:
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 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 USERS:
Possible solution:
You may have plugged your modem’s phone cord into a digital line.
Contact the department responsible for your phone system 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
connection.
Note:
Due to current FCC regulations, maximum download speed is
limited to 53,333 bps.
Our research has shown that the vast majority of telephone lines in
North America can and do support V.90connections. The V.90 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 technology at this time. In order to achieve a V.90
connection:
• The server you’re dialing in to must support and provide a digital
V.90 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 V.90 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.
• 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.
