My broadband is old and dead. The LINK light of the broadband cat is always flashing.

Hello! There are many reasons for the disconnection, first of all, do a comprehensive antivirus on the computer to confirm that the computer is non-toxic, and then you can follow the steps below to check it:

1. Your broadband is sharing a line with **, check whether there is a problem with the quality of the **filter, you can unplug the connection of the ** machine to see if it solves the problem.

2. The new ADSL cat is still disconnected, indicating that it is a line problem.

3. The line problem is one of the main reasons for the disconnection, the line is aging, wet, poor contact, loose connection cable crystal head, and the port problem of the computer room.

4. Network card or network card driver problems may cause disconnection faults.

The above methods do not solve the problem, you can call the broadband operator's ** and ask them to deal with it for you.

When my cat signal light flashed, I ran downstairs to lift the fixed earpiece and put it back, the signal light has been on, and there has been noise, I guess it is the reason for the wiring, that is, from the entrance line to the separation box, let the telecom people reorganize the line at home, it must be line interference.

Supplementally, the separation box is also a filter or frequency divider ADSL and **share** different frequency bands of the line, but there will be mutual interference due to the quality of the line, so the installation of ADSL divider can be solved (a small square box).My family used to have a very stable signal, but the separator was changed to a different connection, and it was always unstable.

It may be a problem with the line ** line has also appeared in my home before It may also be a problem with the terminal of the telecommunications room My family used to flash as long as a dozen **link and so on Annoyance was very annoying Later, I changed all the lines ** Don't plug in It's OK My home used to be telecom may have come 8 times I'm speechless By the way, I forgot to say that my home ** used to be through the line is also on the side of the no problem But I can really use it so well

Look at the crystal head, whether the crystal head is not in good contact.

It may be that the signal is not good, and the link light on the router represents whether it is in normal working condition. If the link light is on, it means that the connection is successful; If the link light is not on, it means that the connection fails. Usually, this problem is caused by a cross-over problem with the network cable, when the router we are using is connected to a different cable

modem or adsl

The modem needs to switch between different network cables, and the network devices corresponding to direct connection or crossover are not the same. There is an MDIX button on the back of the broadband router that is responsible for switching between direct connection or crossing, if the link light cannot be lit, you can try to use this button to solve the problem.

The following is what netizens have also appeared:

The link light is the one that indicates the status of the channel between your cat and the telecom. Normally, it should be solid on.

If the link light flashes, there is a problem with the channel of the cat and the telecom. There are three possibilities: there is a problem with the cat, or there is a problem with the line, or there is a problem with the telecom settings.

Don't let the telecom people cheat, it's not your network card's problem. Find someone in the telecom to change the cat, or repair the ** line, or they artificially set up the problem. Otherwise complain about him.
