Problems Connecting to the Internet; Dial-Up Modem Troubleshooting (Windows XP, Me, 98, and 95)

  • PrintPrint
This document applies to Microsoft Windows XP, Me, 98, and 95.
NOTE:Because of actions taken by Internet Service Providers, HP recommends upgrading the modem driver after experiencing connection problems. For best results, see Updating Drivers and Software with Windows Update . For certain 56K Flex modems, you might need to check with your ISP to see if it is still supported.
This document contains solutions for the most common modem problems. Connection problems might result from poor phone transmission lines, bad phone jacks, high traffic on Internet Service provider phone lines, or modem drivers and software that are incorrectly configured. This document helps resolve these types of problems.
NOTE: This document does not address Digital Subscriber Line (DSL) or cable modems. If you are using a DSL or Cable modem, see Resolving Cable or DSL Modem Internet Connection Problems .

Before you begin

You need the following items to resolve your problem:
  • A working telephone cord that is six feet long (1.83 m) or less (RJ11).
  • A working telephone (analog).
  • A working telephone connector (a wall jack).
    NOTE:If the telephone wall connection is more than six feet (1.83 m) away, move the computer and monitor close enough to connect the telephone cord directly.
  • An Internet Service Provider (ISP) so you can connect to the Internet. Have your account already set up, with a dial-up number available.
  • A printed copy of this document

Step 1: Checking phone line quality

Checking phone line quality might help resolve intermittent disconnects and slow modem transfer rates. Turn off devices that use radio waves (such as 900 MHz phones) and complete the following steps:
  1. Unplug the phone line from the back of the computer and connect it to a normal analog telephone (not digital) so that the telephone cord runs from the wall jack directly into the telephone. Make sure the telephone cord is not wrapped around any other wires and is not near home stereo speakers. Lift the phone receiver and check for a dial tone.
    NOTE:How can you tell if your phone system is analog or digital? Examine the back of the telephone connected to it. If the phone has an RJ11 (only two or four contacts) connection and a Ring Equivalence Number (REN) listed underneath, the phone and the line are probably analog. If you need to dial 9 for an outside line or the phone uses a tone for a ring, the phone is probably digital. This article does not address digital phone systems as they are not designed to work with dial-up modems.
  2. If there is no dial-tone connect the telephone cord to another wall connection.
    • If you still cannot hear a dial tone, the telephone cord might be bad. Replace the telephone cord and try again. If you continue to hear no dial tone after replacing the telephone cord, contact your telephone company to check the telephone line and wall connections.
    • If you get a dial tone after replacing the telephone cord, or after fixing the wall connection, continue with these steps. If you still get no dial tone after all trying these external hardware checks, continue at Step 2: Checking the modem connection
  3. If you hear dial tone , check the telephone line for quality. Dial a friend and listen for static or other voices on the line. If the connection appears normal, continue at Step 4: Fixing no dial tone issues . If you can hear other voices or static, there might be a problem with your telephone lines. Contact your telephone service provider to repair the line.
  4. Using your telephone, call the number your ISP gave you to connect to the Internet. If the ISP accepts the call, you will hear high-pitched squealing noises (the noises are tones that the ISP uses to connect to modems). If the line is busy or stays silent, make sure you are dialing the correct number. If you dialed the right number and you still cannot connect, continue at Step 5: Contacting the ISP .

Step 2: Checking the modem connection

You might have a connection problem between your phone line and the modem. Use this step to determine if this is the case.
  1. Remove all other devices that use the same telephone number as the modem, such as an answering machine, fax machine, or caller ID box. These devices might weaken the telephone line signal going to the modem.
  2. Check the back of your computer to make sure the telephone cord is connected into the telephone Line-in jack.
    NOTE:The Ethernet LAN connector is wider and used for a LAN, DSL or cable modem connection. The LAN connector is sometimes confused with the telephone Line-in jack. The telephone line-in jack is usually near the bottom of the computer, and might be green.
    Figure 1: Modem jacks
    1 - Telephone-out jack
    2 - Line-in jack
    NOTE:Some computers have one Line-in connector with a label such as Wall or Telco , while others have graphic labels.
  3. If the computer is on, turn it off:
    • In Windows XP : click Start , Turn Off Computer , and Turn Off .
    • In Windows 95/98/Me : click Start , Shut Down , and Shut down .
  4. Wait a minute before turning the computer back on.
  5. When Windows opens, try connecting to the ISP.

Step 3: Turning off call waiting

Sometimes your Internet connection ends because someone called while you were online and you have call waiting. This can be true even if you are using the modem-on-hold feature. Turn off call waiting before you connect to the Internet to resolve this problem. (If you know that you do not have call waiting, click here to continue at Step 4: Fixing no dial tone issues)
Choose your version of Windows below and follow the instructions:

Windows 98 and Windows Me

  1. Click Start , Settings and Control Panel .
  2. Double-click the Modem icon (looks like a phone).
    NOTE:If you do not see the Modems icon in Windows Me, click View All Control Panel Options .
  3. Click the Dialing Properties button to open the Dialing Properties window.
  4. Select To Disable Call Waiting, Dial: and select *70 , 1170 , or 70# from the drop-down box next to that line of text or type in the number sequence that your phone service requires for disabling call waiting.
  5. Click Apply .
  6. Click OK and close Control Panel .

Windows XP

  1. Click Start , Control Panel , Printers and Other Hardware and Phone and Modem Options .
  2. Click the Edit button on the Phone and Modem Options window.
  3. Select To Disable Call Waiting, Dial: and select *70 , 1170 , or 70# from the drop-down box next to that line of text or type in the number sequence that your phone service requires for disabling call waiting.
  4. Click Apply .
  5. Click OK .

Step 4: Fixing no dial tone issues

Sometimes you might receive an error message that no dial tone was found. This might occur because the signal on the line is too weak, the modem checks for a dial tone too early, or the modem hardware is bad and cannot open a connection. This step resolves these problems.
  • First: If you have voice mail, use a telephone to check for unheard voice mail. Be sure to either archive or delete the voice mail so the system knows you listened to it.
  • Second: Use the following steps to check that the phone line has tone and that the modem can dial out (without having to open the phone line itself):
    1. Restart the computer.
    2. Pick up a nearby phone handset that is attached to the same phone line (same phone number that the modem is using), and listen for the dial tone.
      NOTE:If you do not see the Modems icon in Windows Me, click View All Control Panel Options .
      Make sure that the phone line is not in use.
    3. Try to connect to the Internet (dial your Internet Service Provider) while listening to the handset.
    4. When you hear the modem start to dial, hang up the handset.
      • If the modem connects, continue using this section to remove dial tone checking. This allows the modem to blindly dial the ISP and connect.
      • If the modem does not dial, go to the Advanced Modem Troubleshooting page to determine if the modem is defective.
To remove dial tone checking, choose your version of Windows below and follow the instructions:

Windows 98 and Me

  1. Click Start , Settings and Control Panel .
  2. Double-click the Modem icon (looks like a telephone).
