Helping people with computers... one answer at a time.

If your computer has a clear dial tone but is still showing "no dial tone", check to see if the modem is properly connected to the right places.

Why do I get 'no dial tone' from my computer even though the phone has a clear dial tone.

The most common way this happens is that the computer's modem is simply not connected to the phone line. The dial tone is the modem's only real way of knowing whether there's a phone line there or not.

Make sure the phone line is plugged into the correct socket in your modem, or into the PC if the modem is built-in.

I need to get a dial tone. Does anyone know how to do this?
Is there a number than can be called to get it?
I have a modem in my computer, but I need to get a dialtone to be able to call another number.
Example: I turn longdistance calls into local calls. So instead of programming unlimited number I need it to get to a dialtone so people just have to enter a number.

Look for a Network Adapter Conflict
If you do not have a network adapter, go to the "Check the Regional Settings in Modem Properties" section of this article.
Click Start, right-click My Computer, and then click Manage.
In the Computer Management pane, click Device Manager.
Expand Network Adapters, right-click your network adapter, and then click Disable. If this solves the problem, your modem is conflicting with your network adapter.
Check the Regional Settings in Modem Properties
If your modem is set for the wrong country, it may be "listening" for the wrong dial tone. To check the regional settings:
Click Start, and then click Control Panel.
Click Printers and Other Hardware, and then click Phone and Modem Options.
Click the Dialing Rules tab, click your location, and then click Edit.
Click the General tab, and then make sure that the correct country is listed under Country/region.
Disable Dial Tone Detection
If you cannot determine the cause of the "No Dial Tone" error message, it may be possible to work around the issue by disabling the dial tone detection of your modem. To disable dial tone detection:
Click Start, click Control Panel
Click Printers and Other Hardware, and then click Phone and Modem Options.
Click the Modem tab, click your modem on the list of installed modems, and then click Properties.
Click the Modem tab, click to clear the Wait for dial tone before dialing check box, and then click OK.

I have tried everything possible to get a dial tone. I have 3 ports installed and my pctel modem insists on using com4. I don't know if that's the problem or not, bot no matter what I do I can't get the modem switched to an installed port. Please can you help?

I have a problem with my modem. I changed the modem but there was no dial tone even though the phone is connected to the computer.The other modem that i was using just stop responding I turned my computer on, but the computer does not boot.i have tried to reinstall it but still the same problem.

Using WIN XP with some internal modems I have found this to work.

Click on Start -> Control Panel
If you're using the Category View, Click 'Printers and Other Hardware', then click on 'Phone and Modem Options'. If you're using the Classic View, click 'Phone and Modem Options'
Click on the 'Modems' tab.
Click on your modem so that its highlighted, then click on the 'Properties' button below.
Click on the 'Modems' tab
Uncheck "Wait for dial tone before dialing"
Click OK twice and try to connect again

You should now have a dial tone to your modem.

I have replaced by modem, and it worked for a short period. I then started getting the no dial tone error message again as I had with the factory modem. What causes modems to go bad, or is Windows XP causing a problem?
Thanks fo your help.

December 26, 2005 11:46 AM

I believe it is a spyware program causing it.
I have the same problem. The new one worked once, and stopped working after reboot.
Any one else with this same problem.
Norton found a dialer program and deleted it, but it is not working yet.

I have read the suggestion but still not tried, hoping it will work, beacuse there is some technical thing which I haven't tried.

February 7, 2006 9:01 AM

We are currently getting a "No dial tone detected" message on two different computers in the house. I run Windows 2000. Disabling dial tone detection has no effect.

Furthermore, after failing to dial, the computer will take the phone off the hook. The phone line must be unplugged from the computer at this point.

Hi .. just been beating my head against this problem also and it was down to the cable connecting the modem to the 'phone socket. I'd scrounged a cable 'cos I couldn't find the original .. came across this post ( .. took the time to dig out a 'proper' modem cable and it works!

i had the same problem with the no dial tone error message . after reinstalling the juno software which ,was giving me trouble , i still got the error message. i inspected the modem cable (cheap phone cable)and noticed that there was just a little wiggle in it even though it had clicked into position. the cable was pushed all the way in ,but i still got the error message. i pulled the cable out a tiny bit to where it was still connected properly but now it is pulling away from the back of the computer instead of pushing into it. this got me up and running but i think i will invest in a better cable. hope this helps someone.

I'm having this problem. The computer tells me that the modem itself is just fine. Can I trust what the computer tells me or could I still have a fried modem?
