Was it a random problem?
Given the complexity of the Internet, it’s not unusual for short-lived problems to pop up somewhere in the system. Try connecting again in a minute or two. You can also shut down your computer, wait for 1 minute and then re boot and try again. If your problem mysteriously disappears and never returns, great. If it still happens, especially if you can reproduce it consistently, call tech_support.

Are we down for maintenance?
Internet Service Providers periodically have to do maintenance or troubleshooting on their equipment, which can cause connection problems. ISP’s are not perfect, nor do they know everything all the time; if you’re having trouble and can’t figure out why, you may wish to contact us and let us know.

Please check that your phone line is plugged in to your computer and that it is working
You can plug a phone into the line to make sure you are getting a dial tone.
Also, check to make sure you have the phone line plugged into the correct jack on
your modem (usually on the back of the computer).
The line from the wall should be plugged into the jack labeled "Line", or "Telco" or it may
have a little picture of a phone jack.
Do not plug it into the one labeled "Phone", "Telephone", or with picture of a little
telephone on it. Some modems don't have a label or a picture. If that is the case,
then try one, then the other.

Does windows see the modem?
If windows does not get a response from the modem, it could be really bad news
or it may just have gotten misconfigured.

This can be caused from several things:
There is a 15 minute idle disconnect which means if you are reading or composing a long e-mail you can be "dropped".
There must be data either being sent to or sent from your computer to keep the connection "live".
OTHER FACTORS:
Telephone lines used for voice can sometimes be unreliable when it comes to carrying data. Problems experienced with poor line quality can result in numerous, sometimes inconsistent results, such as inability to make connection, loss of connection and poor data transfer.
•Noise on the phone line or bad phone line/cord
•Phone cord damaged, not plugged in tight or plugged into a bad wall jack
•Any other equipment connected to the same phone line such as an answering machine or FAX.
•Call waiting not disabled
•Bad weather that could be affecting the phone lines
•Modem not seated properly or correct drivers not installed
•Modem is failing

Unfortunately the problem is with Internet Explorer, and it happens occasionally for no
apparent reason. A possible fix is to open Internet Explorer, and go to "Tools" and scroll down to
"Internet Options" at the bottom and click it. Go to the "Connection" tab, and move
the dot from "Never Dial a Connection" to "Always Dial My Default Connection",
and click "OK". Now, restart your browser, and you should be able to connect.
If you still have a problem with the browser you can go to the Microsoft site for help (if you can get your browser to get you to the Microsoft site).

First be sure that you are connecting to a V92 access number.
You can do that by going to the access numbers lookup page found here.
Check the Modem set up instructions that came with your modem.
Make sure you have the call waiting feature from your phone company.
Check that you have the correct drivers installed for your modem, this includes
any updates you may need from the modem manufacturer.
Contact the modem manufacturer.

There may be a few different numbers you may try, depending on where you live.
We have not hardly seen anyone who has gotten a busy signal on their second try,
so we recommend trying again, and you should be able to get on with no trouble at all.
If you do get multiple busy signals, or can hear a "fast" busy signal,
then please contact us, so we can get it resolved.

Open Network Connections
Right-click the dial-up connection you want to configure, and then click Properties.
On the General tab, modify the phone number by using one or more characters from the following list.
Character Functions:
    , (comma) Pauses briefly (two seconds for most modems) before continuing.
    P Switches from touch-tone to pulse/rotary dialing.
    T Switches from pulse/rotary to touch-tone dialing.
    $ Waits for a calling card prompt tone.
For example, when you dial in from a hotel room, you may have to add 9 to the number you are calling to get an outside line.
Your number may look similar to the following: 9,555-0100
The comma after the 9 gives a pause long enough to get an outside line before continuing to dial the full number.
Note
To open Network Connections, click Start, click Control Panel, click Network and Internet Connections, and then click Network Connections. To configure phone number modifiers, you must be logged on as a member of the Administrators group.
By selecting the Use area code and dialing rules check box, and then clicking Rules, you can create a Location for which specific dialing rules automatically apply.
For example, if you frequently connect from home and need to disable call waiting, you can create a location for use from home that automatically dials the code to disable call waiting before the connection call is placed.
If you see unfamiliar characters being dialed before your number, check to make sure the Use area code and dialing rules check box is not selected.
If it is selected, a location may be enforcing a dialing rule that you do not need.
For example, a location may be selected that always dials 1 to accommodate long distance dialing.
