Why does the telecom 8M fiber cat plus router always drop the line?

There are many scenarios of network slowness or disconnection, and further testing is necessary to find out the fault point before targeted troubleshooting, the specific steps are as follows:

1. First of all, the stand-alone device is connected to the telecom optical modem and other equipment to ping the gateway or DNS server address of the telecom, and a numerical value is obtained;

2. Connect the router again (unplug the other network cables) and then ping;

3. Then connect to other computers and ping when it is in normal use;

Get 3 values, which is larger or has packet loss, it means that it is the problem of **, the first time is that the line of the telecommunications company is not good, the second time it means that there is a problem with the router, and the third time if it is abnormal, it means that there is a problem with the local area network.

According to your description, you can do a test, that is, only use your optical modem to connect to the computer to access the Internet (without a router) to see if there is still such a situation, if it does not appear, it means that there is a problem with the settings or hardware of your router, if there is still such a situation, it means that there is a problem with your optical modem or line, and you can call Telecom 10000 to reflect.

I hope to help you, Anhui Telecom wishes you a happy life!

If you have any other questions, you can also log in to the telecommunications online business hall (

Three reasons: (I am a telecom installation and maintenance).

1. Your router is broken, or there is a problem with the settings.

2. The attenuation value of your fiber optical path exceeds the standard value (below 25dbm) and reaches more than 25dbm.

3. Your optical cat is broken, ask Telecom to help you change it.

Don't ask that"Fall 400", he can't even tell the difference between fiber-to-the-home and fiber-to-the-cell.

Check the routing settings to see if you set up automatic connection.

Do you still need cats for fiber optics? Are you mistaken?

Check the line to check if the line is healthy. If the network cable is damaged, you need to replace the network cable. Reworked crystal heads. Here's how to make a crystal head:

1. Buy a few crystal heads at the computer store first;

2. Then cut off the crystal head currently used, strip off the outer skin of the network cable, and expose the 8 cores in the network cable;

3.Arrange the 8 cores in the order of the cores of the previous crystal head;

4. Then cut the core wire neatly and insert the crystal head;

5.Then insert the crystal head into the corresponding network port of the cable clamp and tighten it to ensure that the metal pin is in good contact with the cable.

6. After the production is finished, reinsert the crystal head into the router.

It is a common way to connect to broadband through telecom optical modems, so do you know what is the reason why telecom optical modems often drop offline? Here's a guide to tell you the answer.

01 There are many reasons why the telecom optical modem often drops the line, we need to prescribe the right medicine, such as checking whether the data cable of the telecom optical modem is well connected, if the interface is loose, it is easy to cause the optical modem to drop down.

02 Another reason is that the heating of the telecom optical modem is too serious, and you need to pay attention to whether the heating of the telecom optical modem is more serious, and if this is the reason, you should replace the new telecom optical modem in time.

03 In addition, there is another reason that causes the telecom optical modem to be disconnected frequently, which is caused by the unstable circuit and voltage of the telecom optical modem, so replace the power cord of the telecom optical modem or check whether the voltage is normal.

04 Finally, it is necessary to check whether it is caused by the instability of the background of Telecom, call Telecom customer service** to feedback to the customer service staff that the Telecom optical modem is often disconnected, and need the help of the customer service staff.

The wireless router is not set up, so re-set the wireless router.

Do you need to dial up the fiber optic cat to connect the wireless router as you do:

Plug in the wireless router, don't pick up the cat first, reset the wireless router (restore the factory), connect the computer to any LAN port of the wireless router, enter the router gateway address in the browser address bar (on the label behind the router), enter the settings page, and set it according to the PPPoe (ADSL virtual dialing) method.

Then set the SSID, encryption method, and password. Save, restart.

After setting, connect the network cable from the cat LAN port to the WAN port of the wireless router.

The failure of optical fiber broadband is not necessarily the interruption of the optical cable, it must be tested to accurately determine the fault point, and then troubleshoot according to the scope of the fault point, the test method is as follows:

1. Set up the dial-up connection according to the requirements of the operator, connect the stand-alone device to the operator's optical modem, and ping the operator's gateway or DNS server address after dial-up the Internet;

2. If the ping is not working or the packet loss is serious, it means that the operator's external network network is not connected or malfunctioning, just call ** to find the operator to report for repair;

3. If the ping is normal, it means that the external network network is normal, it has nothing to do with the operator's network, and the fault is on the router.

4. If the router still fails after step 3 above, you can judge that the router hardware is faulty and you can only replace the router.

Fiber broadband, if something goes down, do you know what to do?

If the light shows that the fiber optic line is faulty, it is recommended to consult the telecommunications company. If not, it is recommended to change the computer system for testing. In addition, the optical path instability cannot be ruled out. Network operators can be consulted.

Optical power 19 23 are normal.

If it is found to be lit up for 1 second.

There are 3 possibilities for a red light.

1. If the cat has a problem, play ** for free.

2. If the optical fiber interface is not plugged in tightly, press and hold the cat to unplug the optical fiber head.

I plug it in firmly.

There is a snapping sound.

3. There is a section of line in the middle that goes around.

Just straighten him out.

The fiber cannot be folded at 90 degrees.

Nor can it be bent too much.

Can only be coiled. One by one.

Due to the introduction of optical fibers into households, the Internet access bandwidth has increased a lot, and operators have limited broadband users from using high bandwidth to do other things. Telecom is really rubbish, after upgrading the optical fiber at home, the connection fell several times a day, and the customer service said that the optical fiber was such a ,..

My same problem, 20m optical fiber, installed for more than 3 months, often dropped in the past two days, call ** to the salesman, they asked the cat is not white and black, I looked at it sure enough, give me the conclusion that it is OK to restart, I see that the cat is Bell's, after the restart or not, the salesman changed the problem after the light cat was solved!

It is estimated that the installer has pulled the line not standard, see if the line has been broken. Or over-twisted. The inside of the fiber is glassy and may break (not completely).

One of the points of the fiber optic line is that watching IPTV has no effect on the network speed. So there's no such thing as being too informative and people fooling you. In fact, telecom is very strict, you have to complain a few times.

The custodian will call the boss or change the line. You can scare him--- I will complain you to the Ministry of Industry and Information Technology and guarantee that they will come to the door within half an hour during working hours. In addition, as long as the light cat they borrowed is not artificially damaged, they will replace it.

Don't worry, do what I say, they will scold you in the back, but they do work more than 10 times more efficiently.
