ADSL sometimes flashes and sometimes stops, who knows what the relationship is?

If the link light flashes and the connection drops, it is a signal problem! If you are sure that there is no problem with your line, you can call ** to Netcom and ask him to change the port! ~

Power is always on, that is, the power supply is on.

ADSL under the link light is always on is the signal is on,Flashing is in the connection,Not lit is no signal ADSL under the ACT light is data flow,The same as the ACT light under LAN,Don't care about the LAN under the link light is always on is the cat and the computer network card connection is normal landlord rule it out,As long as the link light under ADSL is not always on, hit **,Until it's good,In addition, you have to turn off the ADSL cat when you change the port,Wait for him to change the port and then open, Generally, it will take about 10 minutes, and if it doesn't work, continue to play ** to change the port.

Addendum: You seem to be an old morning broadband, your cat seems to be an old version, do not rule out the cat breakdown!

Look at your ** if there is any noise, as long as the ADSL CD or Link light flashes, it means that there is a problem with the line, replace the cat to see if it must be a problem with the line, just look for Netcom, this is what I often encounter.

It is related to your ADSL access network cable, which may be aging or poorly contacted, and then it is your ADSL problem, but if you can access the Internet, the network cable has the biggest problem.

If there is information transmission, it will be on, and if it is not, it will be extinguished.

There are five possible causes of failure:

First, the ADSL modem or separator is faulty. Faulty quality of ADSL modems or separators will result in frequent drop-off failures. It is recommended to borrow a set of equipment that can be used normally, and replace it before testing.

Second, the ADSL line is faulty. The residence is far away from the local computer room (usually less than 3000 meters), or there are serious interference sources near the line, which will also lead to frequent dropouts. In addition, it is recommended to use twisted pair wires between the junction box and the ADSL modem, and even if parallel wires are used, they should not exceed 5 meters.

Third, indoor electromagnetic interference. Severe electromagnetic interference in the room (e.g. cordless**, air conditioners, washing machines, refrigerators) may also cause communication failures, it is recommended to keep the ADSL modem away from the above equipment, and do not share a power cord with the above equipment.

Fourth, the network card is defective. Defective network card quality, or drivers that don't match the version of the operating system, can also lead to frequent drops.

Fifth, the PPPoE issue. This is a problem caused by unreasonable installation of PPPoE software in the system or poor software compatibility. In general, Windows XP recommends using the PPPoE protocol and dialer provided by the system itself.

Windows 98 2000 can install the PPPoE dialer that comes with Modem. We recommend that you install system security patches first.

In addition, you should also make sure that the ADSL modem has good heat dissipation and whether the server in the computer room is working properly.

The ADSL light must be always on, if it flashes frequently, it means that the quality of your line is too poor and unstable, and you need to report to the telecom to repair the line.

ADSL old flash.

There are only two kinds of problems: nuclear trapping.

Cat problem. Problems with the line.

It is easy to make because the transmission requires that the quality of the line is not high. Two wires that can be energized can be connected together to play **.

However, ADSL broadband services are different. It requires high quality lines. And now it's all changed to twisted pairs.

I don't know if I noticed, the previous ** lines were all parallel lines, and now after ADSL comes out, it will be changed to twisted pair. (The two wires of the call are twisted together.) Stranded wire is designed to improve the quality of transmission.

If there is a problem with the cat, you can borrow one from a friend to try. If the borrowed one is normal, it means that there is something wrong with your cat. If you use someone else's cat, it's still not normal. That's just a matter of bending the line. Then call ** and ask them to check the line again.

The staff also has serious and unserious, like I used to change my mind to work in telecommunications, ** if the line is not too bad, it will generally help to change. Because changing lines is more tiring. Coax those who can coax, and deceive those who can.

[Q&A].

There is no problem with ADSL old flash, mainly because the signal and current are unstable, and you can use it with confidence.

There is a problem with the line or the port in the data center.

What brand of cat is your network telecom?
