Windows XP - My dialup modem does not connect to the Internet.
- Ensure that the telephone line is connected to the correct jack on the computer.
- Check the telephone line where you are connected.
If it is a business:
- Verify that the telephone line is not on a PBX telephone system, digital telephone line, or another type of telephone system that allows calls to roll from one telephone line to the next.
- The telephone line must be on a direct analog line.
- Determine whether you have to dial 9 or some other digit for an outside, local line.
- Verify that there are no other telephone services on the line, for example voice or call messaging or call waiting.
If it is a home:
- If you have call waiting on the modem line, disable it by dialing a *70 at the beginning of the dialing string.
Note: The *70 may not work in some parts of the country. Reference the local telephone company for accurate information on temporarily disabling this function.
- If voice mail or call messaging is enabled on the line, retrieve the messages before trying to use the modem.
- Bypass all splitters, surge protectors, answering machines, caller ID boxes, or fax machines.
- Find out if a wireless phone jack is being used.
This device plugs into a power outlet and transmits a telephone signal through the house wiring. It is used in areas that no telephone line is accessible. It causes interference in the phone line, and the modem will not work properly while one of these are in use. The modem has been known to dial, and sound as though it is connecting, but not actually connect due to one of these devices.
- Connect the regular telephone into the wall jack to check for a dial tone.
- If possible, try another telephone cord between the computer and the wall.
- Check the length of the telephone cord. It may be too long. Connect with a shorter cord.
- If available, try another telephone jack or telephone line.
- Check for environmental concerns. If you live near any high-power electrical lines, while this is a rare occurrence, close proximity to a power substation or electrical line may cause some interference with the telephone line. Check with the telephone company for this possibility. If possible, move the computer. Otherwise, note the response in the event text and continue troubleshooting.
- If there has been an electrical storm since the modem was used last, the issue may be the cause of the failure. Although the computer may appear to work fine, a lightning strike may have traveled through the telephone lines.
Note: Continue troubleshooting and document the response in the event notes. This information must be included if it is determined that the computer needs to be sent in for service. See the Lightning Strike Policy.
- Disconnect all the telephones using the same telephone line.
- Test the modem. You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings might also prevent you from completing this procedure.
Note: To open Phone and Modem Options, click Start, point to Settings, click Control Panel, and then double-click Phone and Modem Options. This procedure sends standard AT commands to your modem, and displays the responses that indicate features supported by your modem.
- Open Phone and Modem Options in Control Panel.
- On the Modems tab, click the modem you want to test.
- Click Properties, click Diagnostics, and then click Query Modem.
- Test the modem using Hyperterminal.
- Click Start, click Programs, click Accessories, click Communications, click Hyperterminal, and then click Hyperterminal.
- When prompted if HyperTerminal should be the default Telnet program, click No.
- When prompted for a name, click Cancel.
- A New Connection - Hyperterminal window appears. A blinking cursor should be present.
Note: Do not use backspace or retype anything - you may not see what you are typing at first, do not type the same thing over. You will start to see what is being type after the 1st or
|ATX1DT12345||This should pick up line and dial out-if you leave it- it will give the response NO CARRIER|
On the Line above, ATX1DT12345 is generally used for people that have one phone line because it can pick up and dial out on the line while you are talking with the customer.
If you have more than one phone line, replace the 12345 with the following number so you can actually connect to another computer.
Gateway Dial Up Server - 18888880520
This shows you that the modem is working and that it can communicate to another computer.
This is all the other possible commands you can do within hyperterminal.
|AT||Your modem should respond with an OK, letting you know that your modem is plugged in and turned on.|
|ATE1||Echo your command on the screen.|
|ATE0||Turns off the echo to the screen. Some modems will not run correctly with the echo on, so
make sure you turn it off when done with it.|
|ATH1||This is taking the phone off the hook. You should get a reply of OK or 0 back from the modem, a dial tone and an OH indicator on the modem, if it's an external modem.|
|ATM1||Turns the speaker on, this is for the dial tone. ATL0 is the lowest volume. ATL2 is the medium volume.|
|ATM0||Turns the speaker off.|
|ATD||This command will take the phone off the hook as ATH1 did. It will also dial a number if you include it with your command, i.e. ATDT1234567. The T is for tone. Put a P in its place for a pulse phone. If you include a W (ATDTW), it will wait for a dial tone before
dialing. If you include a (,) anywhere after the command, it will pause before continuing to dial. For instance, you may need a 9, for an outside line.|
|ATQ0||This enables result codes. This aids in troubleshooting problems. If you typed an ATV1
prior to this command, you will get back verbose result codes. (OK-BUSY-CONNECT 2400,9600-COMPRESSION; V.42bis) If you type ATV or ATV0, then you will get number or short codes; i.e. 0,12,10.|
|ATQ1||Disables result codes|
|ATH,ATH0||Makes the modem hang up|
|ATZ||This resets you modem to a predefined state. If you did not specify a state, then it will reset to the factory's settings.|
|AT$||Displays some modem string information. Almost like the /? For and MS-DOS commands.|
