Computer Problems (some things to check first)
These are all problems with your computer that may need to be addressed before you can connect to the internet. These are general computer problems and may need to be repaired under warranty or by a computer repair service.
Is the power on?
Is computer operating properly?
Do you have a Blue Screen?
Is the computer running in Safe Mode? (It will say so in each corner of the screen.)
Freezing (can't move the cursor on the screen, keyboard doesn't respond)?
Have you made any changes to your computer recently?
Added any hardware recently?
Added any software recently?
Any recent changes in your software for the printer, Internet security or antivirus?
Have you downloaded any new programs or games recently?
Have your kids or anyone else not familiar with computers been using it?
Try rebooting the computer and trying again.
Norton Internet Security Firewall
Norton Firewall can frequently prevent internet applications from sending or receiving information over the internet even though you are connected. Check the configuration of the firewall and make sure that it is not interfering with internet communications.
What is a modem and why is it important?
When you click on something to make your computer start dialing up, Windows uses hardware in (or connected to) your computer called a modem to connect to MAIN's server. The modem is generally in a slot in your computer (usually in the back) that the phone line is hooked to. It could also be plugged into a port on your computer.
What does a modem do?
A simplified definition: It changes data into sounds so that computers can communicate over telephone lines.
The modem has two functions:
1. It dials a call to our server, making sure that there is an answer and responding to it.
2. If all that is satisfactory, then it switches to data transfer mode and sends your username and password. When that is accepted, the modem handles the data transfer (web sites and email, etc.) between your computer and the server.

Modems and Phone Lines
Many times it is a phone line problem rather than a problem with the modem. Your modem is a critical link in getting web pages and email through it. Weather conditions often will cause significantly different phone line characteristics, and the modem is basically expected to handle them (the phone company doesn't usually do much to correct such troubles.) Manufacturers set the initial modem settings for dialing up in or near a big city with good phone lines, as that is percentagewise most of their clients are. We are in the mountains with phone lines inherited from the many telephone providers that have been here over the decades.
Modem settings are adjustable so you can tune the modem characteristics to the lines that are available. Also, there are multiple protocols that are supported, some of which are not yet standards and therefore are less compatible between offerings from the various manufacturers.
Modem failure modes: Sometimes modems quit working altogether and other times they fail intermittently, working only sometimes or working slower. The dial up function of your modem may fail and you won't call the server or it may call but not respond to our server properly. Or the modem may place the call properly and the data transfer function may be broke or only partially working. Also, there may be several problems that have to be resolved before you can connect again.
Try to connect the most direct way:
Open My Computer (usually in the upper left hand corner of your desktop), then double click on Dial Up Networking, then double click on MAIN (or whatever you named the connection), then click the button named either "Connect" or "Dial".
Windows Millineum Edition (ME)
Go to Start => Settings => Control Panel, double click on Dial Up Networking, double click on MAIN (or whatever you named the connection), then click the button named either "Connect" or "Dial".
Go to Start => Connect To, then MAIN (or whatever you named the connection), then click the button named either "Connect" or "Dial".
Watch the dial up process and if your computer does not connect before your password is verified, try these things:
Problems with getting a dial tone and dialing to the server:
- Check with a regular telephone on the line the computer is using to see if you have a working phone line. Listen for noises such as hum, static, echo and so on when you are on the phone. If there is any noise on the line it interrupts the transfer of data and your computer has to renegotiate the connection with the server. It is the phone company's responsibility to take care of noises.
- Make sure your computer is dialing the right phone number.
- The phone line should be plugged into the back of the computer in the place labeled Line or it will have a symbol that looks like a pyramid made out of blocks. It may or may not work in the place usually next to it that is labeled Phone or has a telephone handset symbol.
- Sometimes, too many things on phone line will cause a problem. If you have a fax, answering machine, the computer and several phones on the same line, the computer may not be able to handle it. Try removing other devices and see if it helps.
- If you have a surge supressor, it may be having problems. If you use a telephone line surge supressor or have your phone line connected to a power surge supressor, the supressor may be causing the problem. Try routing around it and see if that helps.
Reinstall the Modem
If you get "Error 678" and you have a working phone line, the modem in the computer may be having problems.
Here is how you uninstall and reinstall the modem to try to get it working again:
Win 95, 98, ME:
Click on Start then go to Settings - Control Panel - Modems - Properties) and write down the name of the modem as it's listed to refer to later, and the COM port number, clicking the Diagnostics tab to see it, if required, then OK. Make sure the modem is highlighted, click Remove, and confirm the removal if requested, then close everything and shut down the computer (Start - Shutdown - Shutdown - OK.) Turn the power off to the computer if it has to be done manually, then wait a few seconds and turn it on again - the modem may be reinstalled by Windows and oftentimes will then work better. Go back to where the modem was listed the first time using the instructions above and see if it reinstalled the modem and check to see if it is the same thing that you wrote down. If the computer can't find the modem or the driver (the software that runs the modem), you will probably need to use your warranty or call a computer repair facility.
Go to Start, then go to Control Panel (if you see Pick A Category, click once on Switch To Classic View on the left hand side), then click on Phone and Modem - Modems tab - Properties.) Write down the name of the modem as it's listed to refer to later, and the COM port number. Make sure the modem is highlighted, click Remove, and confirm the removal if requested, then close everything and shut down the computer (Start - Turn It Off - Shutdown - OK.) Turn the power off to the computer if it has to be done manually, then wait a few seconds and turn it on again - the modem may be reinstalled by Windows and oftentimes will then work better. Go back to where the modem was listed the first time using the instructions above and see if it reinstalled the modem and check to see if it is the same thing that you wrote down. If the computer can't find the modem or the driver (the software that runs the modem), you will probably need to use your warranty or call a computer repair facility.

- Make sure you have entered your password correctly.
- It must be entered exactly uppercase/lowercase specifically as it is written on your information or it will not work.
- Make sure zeros are not uppercase "O"s and vice versa.
- Make sure your Caps Lock is off
- If your account is locked due to nonpayment, you password will be rejected. Call the Administrative number if you need to check your account status.
- Windows frequently forgets passwords. You can create a new user and see if Windows will then remember passwords. If you need help with this, contact the HelpDesk.
- If you have Windows 2000, you may need to uninstall/reinstall Client for Microsoft Networks
- Note: Windows XP will always show a password as 16 dots for security purposes. It does not reflect the actual length of your password as you entered it.
If your computer does not connect after password is verified:

Check Modem Settings
Win 95, 98, ME
Click Start - Settings - Control Panel - Modems - Properties - Connection - Port Settings; change the Receive Buffer to Low (1). Now click Okay, then click Advanced and change to Software flow control by clicking it on the upper right. Now click Okay (twice), and then either Okay or Close (whichever you have there) and finally, close the Control panel.
Windows 2000, XP
Go to Start, then go to Control Panel (if you see Pick A Category, click once on Switch To Classic View on the left hand side), then click on Phone and Modem - Modems tab - Properties, then Advanced tab-Advanced Port Settings; change the Receive Buffer to Low (1), make sure Transmit is on High (Maximum), then click Okay. Next, click Change Default Preferences and change Flow Control from Hardware to X On X Off, by clicking on the black triangle at the right side of the box. Now click either Okay or Close (whichever you have there) on all buttons and finally, close the Control panel.
Check Dial Up Networking settings for Windows 95/98/ME
Go to Start, then Settings, then Control Panel. Doubleclick on Network
Make sure you have Dial Up Adapter, TCP/IP, Client For Microsoft Networks
In the Network control panel check these:
Other possible fixes for those using Windows include:
- Network control panel => TCP/IP -> Dial Up Adapter => Properties => OK => WINS Configuration => Disable WINS Resolution
- Network control panel => TCP/IP -> Dial Up Adapter => Properties => OK => DNS Configuration => Disable DNS Resolution
1) Use Google or your favorite search engine to search for the name of your modem (written down in the steps outlined in the first paragraph
of the Windows section.) Whenever a new driver for a modem is released,
it's an indication that there were problems with the prior versions (which
may be common in our rural service area, though not so much so elsewhere.)
2) Research that modem at www.modemhelp.org
- they have an enormous list of modems, with links to other pages on the web, including manufacturer (and other) sites with download-able driver software (which contains
fixes for known problems.)
3) Click Properties in the Modem Properties window and change the
maximum speed setting to 38,400, then click OK. You can come back to this point and adjust it up or down repeatedly as you test the performance of each possible setting. Note that some modems ignore this entirely, and you'll need an INIT string to do this (see #5 below.)
4) In the same Properties window as #3, click Connection, then in
a) 2000/XP -- click the Advanced tab->Change Default Preferences and change the Compression entry to Disable.
b) 95,98, or ME- click Connection->Advanced and turn off the check mark in the upper left called "Compress Data".
5) If no driver is available, or it doesn't help, then look for an "INIT string" that will disable (or force) the various protocols (e.g. V.92, K56Flex, V.90, V.34) - basically, the older, well-standardized protocols V.34 and V.90 are more likely to work properly, regardless of conditions. Write down or print out all the strings recommended for that modem type and try each one individually, using the instructions available on that page of their website.
Disconnect If Idle
Try this when you are in Internet Explorer: Tools - Internet Options - Connections - MAIN - Settings - Advanced -- opens a small window where you can turn off Disconnect If Idle. Click OK at the bottom of all windows until you get to the Control Panel and close that also.
Disable Call Waiting
To disable call waiting, open you MAIN dialup connection.
Click in front of the number to dial up and put:
(the most common number to dial to disable call waiting)
(used in some areas)
If you are not sure which one to used, there should be a place in your telephone book in the info section located at the front which will confirm which number it is (or call the phone company). The commas tell the modem to wait, to give the phone company time to do what it nees to, to allow Call Waiting to be bypassed.
If your computer connects with Windows XP but you can't access web pages or email:
To Un/ReLink Outlook Express and Internet Explorer in Windows XP
This is caused by a communication problem between Windows XP and Internet Explorer- Outlook Express.
XP does not send the web (or email) information to Internet Explorer- Outlook Express,
so web pages or email donít work properly.
Redoing the connection to Internet Explorer- Outlook Express fixes the problem in less than
half the cases, but it is worth a try.:
Close all windows and programs and make sure you are not connected to the internet.
Go to Start => Control Panels => Internet Options (if you do not see it, click on
Switch To Classic View on the left hand side).
Double click on Add/Remove Programs, click ONCE on Add/Remove Windows Components.
Find Internet Explorer and Uncheck it. Click Next. Click Finish.
Click ONCE on Add/Remove Windows Components.
Find Internet Explorer and CHECK it. Click Next. Click Finish.
Close all windows, connect and try web pages and email again.
