Do you have a Broadband connection to connect to the INTERNET, then there are many chances that the error codes mentioned below are quite familiar to you. Check out to see how to fix these broadband error codes and get some technical detail of these error codes.
1) Error code 619
Broadband error 619 – The port is disconnected
Error 619: The port is disconnected
Quite a common error when another application / process requires the same port as being used by the broadband / Internet modem. In particular, fax software is often associated with error 619. If you encounter error 619 while using fax software – disable the fax software and reboot. The quick / common fix for Error 619 is to shut down / reboot, thus forcing the port to close.
To fix error 619, try the following steps:
1. Restart / reboot PC. Wait until all applications have loaded before reconnecting.
2. Check all modem, phone cables and filters.
3. If error 619 persists – uninstall and reinstall your Broadband modem. Sometimes, error 619 can be caused where old ISP modem software is conflicting with newer modem software.

3. If error 619 persists – uninstall and reinstall your Broadband modem. Sometimes, error 619 can be caused where old ISP modem software is conflicting with newer modem software.
How to Fix: Restart your computer and wait until all applications have completely loaded before trying to reconnect. Check your modem and phone cables are connected securely. If your problem has still not been resolved uninstall and reinstall your Broadband modem.
2) Error code 629
Error 629 – The port was disconnected by the remote machine
Error 629 generally means that the remote computer (ISP) is closing /disconnecting the port. This might be due to incorrect connection settings such as incorrect username and / or password. Having checked these settings, if error 629 persists, it would be wise to check ISP server status for any server outages or other ISP related problems.Having checked connection settings, ISP server status – the next step would be to check all modem connections, cables and broadband filters – followed by a PC and modem reboot. If Error 629 has still not cleared, you may wish to revert to either local or ISP technical support.

4)Broadband error code 633
Error 633 – The port is already in use or is not configured for Remote Access
Error 633 is similar to Error 619 error and is caused by other applications attempting to use the broadband modem,incorrect connection settings and sometimes a corrupt modem driver.Error 633 can usually be resolved with a PC restart. This works half the times. If this Fails, error 633 might require the user to disable any Firewall Software. Try to connect again. Recreate the connection and finally, try uninstalling and reinstalling the Modem.

5) Broadband error code 645
Error 645 – Internal authentication error
How to Fix for error 645
It occur with users of Windows 98 or Windows ME .
It occur with users of Windows 98 or Windows ME .
Windows 95/98 – This error can occur if the Require encrypted password option is enabled on the Server Types tab in the connection’s properties, or an incorrect user name or password have been entered.

8) Possible solution / fix for error 678
Broadband error 678 – There is no answer
Error 678 can normally be resolved by restarting and waiting until all applications have completely loaded before trying to reconnect.

How to Fix Error 678:
Click on the Start Menu and then select Run.
In the box which appears type the word command in order to open the command prompt and then click OK.
In the black command prompt window, type “netsh interface ip reset log.txt” and click on Enter on your keyboard.
Then type exit into the command prompt and then click on Enter on your keyboard.
Now restart your computer and reconnect to the Internet.

9) Possible solution / fix for error 691
Broadband error 691 – Access denied because username and/or
password is invalid on the domain
With all Windows versions – Error 691 can occur if you use a bad username or password; remember in most instances the password is case-sensitive – you will not see the password, so if CAPS LOCK is not the way you expect it, you may have a problem with upper/lower-case. It may also occur if there is a problem with your service providers access equipment, or on a ‘bad’ connection where the modem is retraining. Can also occur with incorrect Connection settings.
If you get error 691 with a new account – you may not be using the correct username and/or password. Verify with your provider exactly what you need for your username and password.

10)Possible solution / fix for error 718
Broadband error 718 – PPP timeout
Error 718 indicates a PPP conversation was started, but was terminated because the remote server did not respond within an appropriate time. This can be caused by poor line quality or a problem with the server (ISP). This error can occur when your modem has connected to the ISP and has sent user name and password, but there is no response from the server. Sometimes, re-dialing will be successful.Error 718 can also occur if your ISP account has expired, or if the user name or password you are using is invalid. Error 718 can occur if you have LCP extensions enabled in the TCP/IP Properties of the connection and your ISP does not support LCP extensions.
Error 718 may also occur if you have one or more network cards in your machine, and the cards do not have TCP/IP protocol enabled, or if the TCP/IP settings are incorrect. (Go to Networking in Control Panel to examine the properties of your network adapters; or, if you are not using the network card(s), disable them in Control Panel->System->Hardware.)

11) Broadband error 721 – Remote PPP peer is not responding
Error 721 generally means that there is a problem with the remote PPP
The PPP server resides with the Internet /broadband provider and is the computer at ‘the other end of the line’ that establishes connections to the Internet.
- The majority of Error 721 messages are caused by a problem with the Internet service provider. Check the ISP’s service status before checking other possible causes.
- Displaced modem connections, adsl cables and / or broadband filters. If an Error 721 message has not been caused by the ISP, check all connections. Shut down both modem and PC and to wait 5-10 minutes before restarting them. Wait until all PC application have fully loaded before attempting to reconnect to the Internet.
How to fix error 721 :
Test the dial tone of your telephone to check that your line is working. Unplug, reboot and plug in again your modem to ensure the driver has loaded.
