- Error 679: Cannot Detect Carrier
Mentioned below are possible reasons why these problems appear on your computer:
- Dialing incorrect number
- Line usage by other device
- Faulty Cabling
- Problem with Internet service provider
Dialing the incorrect number
This is the most common reason that these errors do occur. You may have dialed an invalid access number or the access number that you have been using for some time may no longer be active. To solve this problem, you should recheck the numbers that you have on the dialer.
Line usage by other device
For those who use 56k modems, which occupies the phone line while it is in use. It may be possible that another device may already be using the line when you try to dial a connection. Someone may be in the middle of a phone call, a fax message, or another computer may have already dialed a connection. Just check to make sure that no other device is using the line. This is much easier if you have few or no splitters in use.
Loose and faulty cables can be the possible reason for the Internet connection failure. There is a possibility that some cables still work for short duration and can fail for the rest of the time. You can manually check each cable to make sure that they are secure and connection is established. If all connections are secure, you should start replacing non functional with working cables.
Problem with your Internet service provider
Lastly, there may be some problems with your Internet service provider. In this case you cannot resolve this problem as you do not have access to the ISPs equipment. Your only course of action would be to call your ISP and complain about your connection.
