  • > Error 678: Remote modem not responding

    Several factors can cause the ‘Remote modem not responding’ error. The following information should help you to identify the cause of the error and resolve this issue.

    A. Check that your modem is properly connected

    There are two modem outlets on the back of your computer. The correct outlet will be labeled as Line or will have a picture of a wall jack next to it. Please verify that the telephone cord is connected from the wall jack directly into the correct modem outlet.

    If you have other devices connected between the wall jack and the modem (such as fax machines, caller id boxes, or other phones), these could be interrupting the dial tone. Disconnect any devices other than the modem and try reconnecting to NetZero. If this resolves the problem, reconnect the devices to a different wall jack.

    B. Check your Modem settings

    Windows 98/ME Users:

  • Click the Windows Start button, point to Settings and select Control Panel.
  • Double-click Modems and click the Properties button.
  • Set the speed for your modem from the Maximum Speed, menu. For 14.4 modems use 19200, for 28.8 modems use 38400 and for 56k use 57600.
  • Make sure Only connect at this speed is not checked
  • Select the Connection tab.
  • Under Call Preferences, ensure that the box marked Cancel the call if not connected within is unchecked. Some modems may not allow you to change the call preferences.

  • Retry your NetZero connection.

    C. Check your Dialup settings

  • Make sure you have the NetZero software configured to dial your local access number number correctly. Some areas may require you to dial the area code plus the number even if you are dialing into the same area code. You may want to call your operator to find out the proper methods for dialing numbers in your area.
  • Click here for more information about setting up the dialing portion of your NetZero software.
  • If you are trying to disable your call waiting, make sure that the correct code is being used.
  • If your phone requires pulse dialing, make sure that you are not using tone dialing.

    D. Change your access numbers

    Note: If you are subscribed to NetZero’s Toll-Free service please skip to step E.

    If you are having trouble connecting to the NetZero service, try changing the access numbers you currently use to connect.

    Change access numbers and verify your dialing preferences

    Sometimes a bad access number may prevent you from making a successful connection. Pay special attention to the number listed on your NZTV screen during the connection process. If your connection fails after dialing the first access number, try removing that number from your selected list of access numbers and add other numbers that are local to you. Also, verify your dialing preferences.

    WARNING: THE USE OF SOME TELEPHONE ACCESS NUMBERS MAY RESULT IN LONG DISTANCE CHARGES. IN SELECTING YOUR ACCESS NUMBER(S), PLEASE NOTE THAT ALTHOUGH AN ACCESS NUMBER MAY BE IN YOUR AREA CODE OR LOCATED IN YOUR GENERAL GEOGRAPHIC REGION, IT MAY NOT NECESSARILY BE A LOCAL NUMBER FOR YOU. YOU MAY INCUR SUBSTANTIAL TELEPHONE CHARGES IF YOU CHOOSE ACCESS NUMBERS THAT ARE NOT COVERED BY YOUR LOCAL CALLING PLAN. WE URGE YOU TO CHECK WITH YOUR TELEPHONE COMPANY TO FIND OUT WHICH NUMBERS ARE LOCAL FOR YOU BEFORE USING A NUMBER FROM THIS LIST.

    To change access numbers and verify your dialing preferences:

  • Double-click the NetZero icon.
  • Click Settings on the Welcome screen and then click Locations.
  • Select your location (e.g. Home) and click Modify.
  • On the Set-Up a Dialing Location screen, verify the number of the telephone line connected to your computer. Do not turn off call waiting unless you have it enabled/active on your telephone line.
  • Click Continue.
  • The next screen allows you to select local access numbers. Check all the local numbers available to you. If you dial 10-digits to reach someone within the same area-code, check the Area Code box for each selected access number. If you dial 11-digits to reach someone within the same area-code, check the Dial 1 and Area Code boxes for each selected access number.
  • Click Continue and then click Finish to proceed to the logon screen.
  • Retry the NetZero connection.

    E. Add three commas to your custom suffix

    Try using three commas in your suffix

    Entering three commas after the phone number may solve connection problems. Try the following steps:

  • Double-click the NetZero icon on your Desktop.
  • Click Settings on the Welcome screen and then click Locations.
  • On the Dialing Location screen, highlight your preferred location (i.e. Home) and click Modify.
  • On the Set-Up a Dialing Location screen, click Advanced.
  • On the Advanced Dialing screen, type three commas ,,, in the Suffix text box and click Continue.
  • Click Continue, and click Continue again.
  • On the Congratulations screen, confirm that the numbers you have chosen are displayed and that the three commas are included in the suffix.
  • Click Finish and retry the NetZero connection.

    Placing 3 commas after the phone number will pause your computer’s modem to wait for the signal (56K) coming from your access number’s modem. If some brands of modems do not receive the signal immediately, they will automatically disconnect or look for the next connection speed (33.6k, 28.8k, etc). Although your access number’s modem tries to connect at 56K, your computer’s modem may try to connect at 33.6k or lower, possibly resulting in no connection at all.

    F. Upgrade your modem drivers or enter an initialization string

    Modem drivers and initialization strings help your modem communicate properly with our servers, thus ensuring a more stable Internet connection. You can download modem drivers and obtain initialization strings for most modems at:

  • > Connection Failure – The memberID or password you have entered is incorrect or problem connecting to the Internet. Error 691 or 1273

    Important ! Be sure to enter your password all in lower case. If your password is not working, please check to see that your Caps Lock key is not active. Note: If you forgot your password, there is a Forgot my Password button on the Logon screen.

    If you have recently upgraded to or downloaded the latest version of the NetZero software and are receiving this error, please click here.

    The 691 or 1273 error can be caused by several factors. The following information should help you to identify the cause of the error and resolve this issue.

    A. Are you entering your Member ID and Password correctly?

    Ensure that you are entering your NetZero Member ID and Password correctly. Note that your Member ID is everything to the left of the @ symbol in your email address. For example, the Member ID for bobjones@netzero.com is bobjones.

    Be sure to enter your password all in lower case. If your password is not working, please check to see that your Caps Lock key is not active.

    Note: If you forgot your password, remember that there is a Forgot my Password button on the Welcome screen.

    B. Was your account successfully created?
    If your NetZero account was created, you should have seen the confirmation screen below with your new account information. In addition, if you were ever able to successfully log in to your account, it should be valid.

    C. Do you have the software set to automatically remember your Password?
    Sometimes, the password entered into the NetZero software may be changed. This can happen if, for example, someone accidentally presses a key on the keyboard. If you are sure your password is correct, delete the password currently in the software and re-type it. If the password was accidentally changed, this will fix the error.

    D. Have you reset your password recently?
    If you have reset your password recently, make sure to enter the new password into the NetZero software, especially if you have it set to remember your password. If you are unsure which password the software remembers, clear the existing password, and enter your new password on the NetZero Log-on screen before attempting to connect. If you never reset your password, it should be the same one you used when signing up for a NetZero account. Remember to enter your password in all lower case letters.

    E. Is your access number valid?

    > Error 633: The port is already in use or is not configured for Remote Access dial out.

        WINDOWS users:

    There are several possible causes for this error. The steps below should help you pinpoint the cause of the problem and offer a solution.

    A. Have you checked your modem and phone cord?
    A bad modem or the phone cord not being plugged in might be the culprit. Make certain that all of your phone line connections going in and out of the modem are tight and secure, then try to connect to NetZero again.

    B. Have you completely restarted the computer?
    Try shutting down and unplugging the computer for 1 minute. Restart the computer and try to connect to NetZero again.
    Note: If you have an external modem with a separate power cord, once the computer is shut down, unplug the modem power for 1 minute, plug the modem back in, then turn on the modem and restart the computer before attempting to dial again.
    C. It is possible that another program has accessed your modem and has not released it.
    It is possible that another software program, such as fax software, is holding on to your modem. The modem can not dial another number until the software releases it. To verify whether your modem is being used by another program, please follow the steps below:

    1. Press and hold the Ctrl, Alt and Delete keys at the same time.
    2. A window appears listing all of the programs/processes running on your system.
    3. For every program EXCEPT Explorer and Systray, click once on each program listed to highlight it, and then click End Task/End Process.
      Note: Each time that you click on the End Task button, you will have to press and hold the Ctrl, Alt and Delete keys to bring the Close Program/Task Manager window back up.
    4. Try your NetZero connection again. If this resolves the problem, close NetZero and restart your machine. Repeat the above steps, clicking End Task/End Process for only one program at a time. Each time you use End Task/End Process, try your NetZero connection again. If you encounter the error again, you will know which program is creating the conflict.


    After disconnecting from NetZero, you can launch the applications that you had closed again by restarting your computer.

    D. Is your modem configured correctly?

    If your modem is not configured correctly, NetZero will not function. To verify that your modem configuration is correct, please complete the following steps:

    1. Click the Windows Start button, point to Settings and select Control Panel.
    2. Double-click the Modems icon.
    3. Select the Diagnostics tab.
    4. Click the appropriate Com Port where your modem is listed.
    5. Click More Info.
    6. If your modem is configured correctly, it should display port information regarding your modem. Click OK to exit.
      Note: If you receive an error message, then you will need to configure your modem. This may require that you reinstall your modem drivers and/or configure your modem settings. If this is the case, you should contact your modem or computer manufacturer for information on configuring your modem. If you are on a LAN (Local Area Network), contact your Network Administrator for assistance.
    7. On your desktop, double-click the My Computer icon.
    8. Double-click the Dial-Up Networking icon.
    9. Click the NetZero icon to highlight it.
    10. From the File menu, select Properties.

    There may be several possible causes for this error. The steps below should help you pinpoint the cause of the problem and offer a solution.

    A. Have you checked your modem and phone cord?
    A bad modem or unplugged phone cord might be the culprit. Make sure all of your phone line connections going in and out of the modem are tight and secure, then try to connect to NetZero again.
    B. Have you completely restarted the computer?
    Try shutting down and unplugging the computer for 1 minute. Restart the computer and try to connect to NetZero again.
    Note: If you have an external modem with a separate power cord unplug the modem once the computer is shut down. After a minute, plug the modem back in then turn on the modem and restart the computer before attempting to dial again.
    C. It is possible that another program has accessed your modem and has not released it.
    It is possible that a program running in the background may be using your modem (such as fax and voicemail software, or another ISP’s software), preventing it from connecting to the Internet. To work around this problem, disable all programs running in the background by following these steps:

    1. Check and see what programs are running by clicking the application menu in the upper-right corner of the Finder.
    2. Select a program on the list (preferably a fax / modem program) to switch to that application, then quit it by going to the File menu and selecting Quit.
    3. Try your NetZero connection again. If this does not resolve the problem, close NetZero. Repeat Steps 1 and 2, quitting one program at a time. Each time you quit a program, try your NetZero connection again. When you stop receiving the error, the last program you quit is likely the one creating the conflict.
    4. Once you’ve found the conflicting program, close it before you logon to NetZero. You can contact the manufacturer to see if they have more information about a solution so you can use both NetZero and this program at the same time.
