Phones work until computer is plugged into jack. then there is no dial tone wither on phone or modem. cannot connect. called tech support for internet, they said problem is with line. called tech support for phone line, they said problem is with internet. changed jacks, changed phone lines, only one place to plug it in in back of computer so have not made classic error. modem tests okay, computer says modem is in disconnected state when not attempting to connect. Any ideas?

    If everything works until you plug it into the modem, it sounds like the modem is NOT ok. I assume you are using the same lines on the phone and the modem, so the lines are ok? What is testing your modem, the software?

No dial tone


  • First, try to check every telephone line is properly plugged into its phone jack. If you have a problem with just one phone, plug a different phone into that jack. If the second phone works, the problem lies in the first phone.
  • Then unplug each phone and answering machine in your house, one at a time. Wait 30 seconds after unplugging the first device. Pick up another phone to see if there's a dial tone -- if there is, then the first phone may be faulty. If not, continue unplugging phones in the same way and check for dial tone. If you find a phone that doesn't work, plug all your other phones back in and see if they work properly. The faulty phone should be replaced.
  • or disconnect the plug from the test jack inside the exterior box. This disconnects your inside wiring from phone company's line. If you have more than one line, select the test jack for the line that is causing the problem. Plug your phone into the jack; this plugs you directly into the phone company's line. If you have a cable modem, plug the phone directly into the jack on the modem.
  • Then pick up the phone receiver to see if there's a dial tone. If there's no dial tone, the problem is with your outside wiring. If there is a dial tone, the trouble is caused by your inside wiring, equipment or jacks.
  • Hope it will help you. Thanks for using FixYa.

    Fax problem


    I want to make sure I understand this completely. You get no dial tone from the fax machine when hooked up to VOIP. In the past, was there an audible dial tone from the fax, or did it just dial silently and give you an error if there was no tone? When you said you got a dial tone by connecting a phone to the ext phone port of "the machine" did you mean the fax machine? If you get a dial tone by running a phone through the fax machine, then the line is good. I have used a fax machine over Sunrocket before they went defunct, which used the same technology base as Vonage - so it should work. If you used to get an audible dial tone when using the fax, and no longer do, and you are geting a dial tone on a regular phone that is connected to the ext. port of the fax machine, then the problem has to be in the fax machine itself, not the VOIP. If you can verify that, we can go from there.

    Tip

    Troubleshooting for modem.


    Problem:-
    User's modem does not dial or does not connect.
    Tip:-
    Prove that computer is connected with phone line and check that phone line contains dial tone.Therefor check that connection is connect or not.
    • Connection may not be less than six feet (1.8 meter).
    • Check dial tone by plug in the phone in phone jack.
    • If user has many more services (such as call waiting,call messaging OR voice mail) then check that these all are cleared or not and check call waiting is disabled while using modem.
    • Disconnect any answering machine,fax machine or printer which are on line with modem.
    • Check that are you not using digital,rollover or PBX line?These type of lines not works with modem.
    • Try with another phone line. (For this, you have another phone number or another phone line).If user connected with another line then you need to complain in phone company.
    • Try to connect modem with low connection speed.

    Cannot connect to isp using modem (dialup) get error code 680. using vista home premium.


    error code 680 means there is no dial tone.

    manually attach a phone to the phone jack you are connecting to and check if there is a dial tone. if there is no dial tone on that jack try a diff phone jack. if still fails call your telco.

    if there is dial tone to other jacks it means the previous jack is faulty or damage.

    No Dial tone using Symantec Winfax Pro 10 on Windows 98


    Check the physical connection of the phone line to the computer make sure that it is connected to phone line symbol of the Ethernet adapter. Then make sure that the driver of the adapter is installed properly on the computer or you can try to scan the hardware first before the re-installation of the driver using the adapter.

    I am trying to use the fax facility on my epson600fw.my isp is aol .Problem no dial tone. What connections are necessary............via printer,modem & computer ?


    Typically, a fax machine is connected directly to a telephone wall jack with a known working connection. Try plugging the fax machine directly into a wall jack first and pick up the handset on the fax machine if it has one. You should get a dial tone. Then try to fax something to someone you know.

    The machine can also usually be routed through the modem in a computer by connecting the "line" cord on the modem to the wall jack and plugging the fax machine into the the "phone" jack on the modem. You may need to install the software that came with the fax machine to get this to work.

    If you have no dial tone, check the wall jack with a known to be working single line phone. If there is a dial tone, it's something to do with fax machine, the computer modem or the connections.

    Some fax machines can take advantage of internet faxing through a cable modem or DSL connection. Check your manual for the options available.

    Trying to launch internet explorer.it gives me error 680.


    680 - There is no dial tone.

    All versions of Windows are affected by this error.
    No dial tone: There are many possible causes of a No Dial Tone Error.
    First, try testing the modem's ability to detect dial tone and to dial by using HyperTerminal with the direct to COM port connect method - see Using HyperTerminal. If you give your modem an AT&FX1 command, and then a dial command, dial-tone detection will be disabled; if you still do not get dial tone, the modem may not be installed correctly (especially if it is a PCI or soft-modem); or the cable from the modem to the phone-line jack may be bad or installed in the wrong connector on the modem - try another line cord, and make sure you are plugged in to the LINE - not phone - jack on the modem. Plug a regular phone into the phone jack on the modem and make sure it has dial tone. The modem may also be defective. Many new modems come with an electronic circuit instead of the traditional electro-mechanical relay used to take the modem off-hook. Some of these designs are proving less reliable; often, they will be 'stuck' in the off-hook position, so unplugging, the plugging in the phone cord may give dial-tone. If this is the case, the modem needs repair or replacement.
    If the modem will blind dial (x1), but not detect dial-tone otherwise, the problem is likely to be in the proper selection of the Country in Windows->ControlPanel->Telephony or in improper installation of the modem or lack of support for your country in the driver you are using. Check to see if there are updated drivers for your modem.
    If the modem dials properly with detection (x3) in HyperTerminal, but does not detect dial tone when using DUNs, the problem may be DUNs (check for upgrade or re-install) or the proper setup and modem selection for the DUNs connectoid.
    For Embarq telephone service customers, this error can indicate that you have a message waiting in your voicemail. Embarq changes the dial-tone sound to a "fast" busy signal when a new message is present in your voicemail box. This "fast" busy signal can confuse the modem into thinking there is no-dial tone present on the line.

    is your computer hooked up dsl or dial up? unplug all the phones and computer from the phone jacks.plug a corded phone into the jack and check for dial. if you don't have dial tone, call your phone company. if you do have dial tone, plug everything in one at a time and see if the phone line goes dead.if it does, the last thing you plugged in is the problem.

    No Dial Tone on phones or modem


    if you have a dial tone when your computer is not plugged in, then the problem ls with your computer[ a possible short in the computer] the phone cord to the jack, or anything in between such as a dsl modem.if you have dsl, be sure your ethernet cord [ that's the wider plug cord] is in the wider jack in back of the computer. it wont fit in the regular phone jack.if you have dial up, be sure the phone cord is in the regular jack not the ethernet port.[if you have one]

    good luck
