Some of these steps may not apply to your computer. Test the modem after performing each step.
- Here are solutions to some common problems with using a dial-up modem to establish an Internet connection
- Resources for troubleshooting modem problems in Windows XP
- Verify that the modem line is connected to a RJ-11 phone jack
and not to a RJ-45 network port
- Verify that the modem line is connected directly to a wall outlet.
Eliminate any devices like a Telephone, answering machine, surge protector, or line splitter. Test with another phone cable and a different wall outlet, if available.
- Verify the presence of a strong dial tone on the same telephone line that modem is attempting to dial out on by connecting a telephone handset.
Note: A no dial tone error message may be due to the software not handling a certain dial tone rather than a specific hardware fault. Around the world there is a variance in the signal quality of the dial tone which causes a report of no dial tone detection. Disable the dial tone detection to correct no dial tone detected by modem error.
- Verify that the latest driver has been installed properly.
Check the version using the install instructions and readme from the software and device driver files for your ThinkPad system.
- Verify that no other software that accesses COM ports is running when the operating system loads (for example: fax software, synchronizing software for handheld devices, communication software, or external pointing devices that require a COM port).
- Verify that the latest BIOS and Embedded Controller when available for the ThinkPad system has been installed.

- Which modem should I use to connect to the Internet?
You should always use your fastest modem to connect to the Internet. For example, if you have a broadband modem (Digital Subscriber Line [DSL] or cable) and a dial-up modem, use the broadband modem because it's much faster.
