Debugging connection problems

   
 

Only 1 customer out of 400 has a problem. Something may not be setup correctly.
Where in the process below are you experencing a problem?


When you click to connect, here is the sequence of events that happens:

1 - Computer finds modem, looks for modem DLL drivers

2 - DLL Drivers load into Windows

3 - If computer finds modem drivers, Windows tells modem to dial, otherwise computer returns "Cannot find modem".
Modem may have been hit by power surge on the phone lines, or lightning.
This usually happens 5 times per year to various customers.

4- The modem dials a phone number. otherwise "No dialtone"
Phone line not plugged into back of computer correctly, or wiring has been chewed by cat.

5- "line busy", otherwise it dials and the modems negotiate a speed.
If "line busy", then call Verizon or whomever your Phone Company is and complain that they need more circuits into your neighborhood
Otherwise, the modem connects to the server and negotiates a protocol, then a speed.

6- If a protocol is not negotiated, it returns Cannot Connect or "computer you are dialing is not answering" which is an incorrect error returned by Windows.
Generally, it's not using the TCP/IP protocol. Some customers using Windows95 or Windows98 have had to re-install TCP/IP into Windows. Some customers have solved this by updating to Windows Dialer version 1.4 on their Windows95 or Windows98 computers. (Not for Windows 2000 or Windows XP!!)

Also check the phone wiring from the back of the computer to the Phone Company's DMarc box.
Plug in a Laptop computer into the DMark box and test from there, to determine if outside phone line or inside phone wiring is causing the situation.
This could also be a Windows error. Start > Settings > Control Panel > System. Click on Performance Tab. Should be NO LESS than 80% free System Resources.
Clean out various programs from the Startup Items, reboot, then run Search & Destroy to remove all Spyware off the computer.

7- If the modems do negiate a speed, it then should take less than 3 seconds to login to the Login Server. This is at the point where it says "Verifying Username and Password".
It should take only 1 or 2 seconds to "Verify username and password". If it takes longer than 3 seconds, then the LoginID or Password are not correct.

8- If it takes longer than 3 seconds to verify, it will probably fail to log in.
Check Dialer settings and disable NetBeui, disable IPX-SPX protocols.

9- If it fails to log in, change Login name and Password to all lower-case letters. Don't use Caps in your account names.


If the PHONE LINE has a problem, like a crackle on the line, etc., then the modems will re-negotiate a speed to communicate at.
If you are connecting at 45,000, 48,000 or 52,000 then the phone line is balanced.
If you are connecting at slower speeds, then

  • (a) remove all other fax machines & other devices off the line. The phone line should go directly into the back of the computer.
    If the speed is still slow, the phone line is not balanced. Call the phone company to balance the phone line.

  • (b) If your building is more than 10 wire miles from the phone company's 'central office' that supplies your neighborhood, then be glad you're connecting at all. Phone circuits degrade over distance.
    Other people have run various tests and nothing has improved their modem speeds, because the phone companies refuse to spend $1 million to upgrade the phone circuits, unless their circuits are zapped by lightning. Grin and bear it.


If the modems are unable to communicate after 3 TRIES, your modem disconnects.
Continual phone line problems exist in various areas.... Bernville, RD#3 Birdsboro, RD#2 Gilbertsville, and other areas where the phone wires travel a distance of 10-14 miles to the assigned "Central Office". Phone circuits degrade over distance. There are people out in the boonies who cannot connect faster than 28,800 - with any ISP, confirming the phone line situations.

   
 

1USA's equipment is the best available. 1USA is a more stable service than any other ISP.
