The router los flashing red indicates that the optical path does not receive the optical signal or receives the optical signal is poor, if the optical path does not receive the optical signal, then the use of the wireless network will be interfered with, so the router will flash red to remind you to adjust.
solution
1. Turn off the power and remove the optical fiber
However, we found that when the router los flashing red, we can first turn off the power, then unplug the optical fiber head, clean the surface of the optical fiber head and the inside of the router jack with a cotton swab, and then plug in the power and reinsert the optical fiber head. If there is no problem with this step, the red light will stop flashing.
2. Check optical fiber lines (tested by professionals)
If after cleaning the connection between the optical fiber head and the router, the router los light will still flash, we can check the optical fiber line again to see if the line is bent or damaged, if such a situation occurs, you can replace a optical fiber line, then the problem of red light flashing should be solved.
3, consulting customer service (failure report by professional on-site service)
If the above two steps have been dealt with, the los red light is still flashing, you can call the customer service of telecom directly, ask them to consult, the biggest possibility is that the external line and the light cat are damaged, they will send special personnel to repair.
[1] The optical interface of the optical cat is faulty, and the optical cat needs to be replaced.
[2] The indoor pigtail connection optical cat connector is loose, plug the connector can be restored;
[3] Some indoor optical fibers are excessively bent. Excessive bending of the optical fiber will affect the total reflection transmission of the optical signal in the optical fiber, so long as the optical fiber is straight;
[4] If some outdoor optical fibers are broken or the optical port of the equipment room is faulty, contact the staff for troubleshooting.
1 Check whether the preceding situation occurs at the optical port on the rear of the optical cat. If yes, plug it back in to resolve the problem.

5 The network cable is broken for some reason, such as being bitten by pets or rats, etc. This situation may occur. Check it.
1. If many have not queried or paid the network cable, when the optical fiber light is found to flash red, do not change the equipment Settings at will, and call the customer service of the network operator for the first time to determine whether the broadband is overdue, if
2, external network failure If through the official customer service query, determine their broadband no arrearage, then it may be caused by the external network failure, the most common is the \"fiber break\
1. The optical signal interface of the router is faulty. The interface may be loose or poorly connected. In this case, you need to remove the crystal interface of the optical signal to clean it and then plug it in again.
2. The router is broken. This rarely happens, because the router is broken, not only the light signal flashes red, but other indicators should also have problems. You can try restarting the router.
3, your broadband arrears. Broadband is basically a consume now pay later model, because you owe so much, the carrier will simply shut down your broadband. In this case, you will need to pay up in order to recover.
1. The optical connector of the indoor pigtail connection is loose or in poor contact. In this case, remove the connector and clean it up.

2. Some indoor optical fibers are bent too much, and excessive bending of optical fibers will affect the total reflection transmission of optical signals in the optical fibers, as long as the optical fibers are straight.
< br >
3, the optical fiber is broken, when the optical fiber bending Angle is too large, the internal fiber has been broken, resulting in the optical signal can not be successfully transmitted in, contact maintenance personnel to rewire.
< br >
4. There is a problem with the optical interface of the optical cat, which belongs to the hardware problem of the optical cat. If there is a problem with the optical interface, the optical signal cannot be transmitted to the optical cat.

5, broadband arrears, now broadband business is basically a post-paid model, operators will shut down broadband services due to customer service arrears for too long, in this case, you only need to pay the arrears.
< br >
6, regional broadband failure, the entire region of broadband may be overhauled or out of the fault in maintenance, in this case you can call customer service to understand the situation, waiting for maintenance personnel to repair broadband.

7, system problems, if the entire area has been shut down, there is a problem with the system, wait patiently, or contact customer service to explain the situation.
A: The router's optical signal has been flashing red. 1. Overage If the optical cat routing appliance provided by the network operator emits red light, try to restart the device or power off for 3 to 15 seconds before restarting it. If it does not return to normal, it may be caused by broadband overage.
2. The external line is faulty. There are many indicators on the optical cat. If LOS is marked under the indicator that emits red light, the optical fiber is faulty or the optical fiber port is closed.
The light signal lamp of the router has been flashing. There are the following solutions. 1, the circuit board can not bear the power for a long time, try restarting the router.
2, check whether the optical signal cable is not plugged in and out.
Broadband arrears, now broadband is basically a postpaid model, because the arrears of time is too long, the operator directly turned off the broadband, in this case you need to pay the arrears to restore.

The optical fiber in the area is under repair or failure, because there are many urban construction projects in China now, the optical fiber may be dug out, the operator is scrambling to repair, this situation only such as the operator will be connected to the optical fiber fault repair.
1. The optical interface of the optical cat is faulty. The optical cat needs to be replaced. Plug the connector in and restore it.

7, light cat power off, wait for a few minutes to re-power to see whether normal. If the fault is still, it is recommended to call customer service directly for repair.
1, Restart the wireless router method one, directly disconnect the router power, about 1 minute later and then plug in the power.
2. The second method of restarting the wireless router is to use the reset button of the router, that is, the reset hole on the rear panel, and press it with a thin and hard thing that can be inserted into it.
3. Restart the wireless router. In method 3, open the browser and enter 192.168.1.1 to enter the wireless router setting screen. 4. You can set other parameters only after you log in. The default login user name and password are admin.
It could be the broadband bill.
Under normal circumstances, the network operator will set up the optical fiber line to the community, and then through the spliter and other equipment to connect the line to the user's indoor light cat, as long as the broadband is not unpaid, the light on the light cat will be displayed as yellow green, and this also represents the \"light signal\" normal transmission. When the user's broadband arrears, the system will automatically disconnect the network, the splitter equipment in the community will interrupt the transmission of the optical signal, the optical cat will receive the optical signal will alarm, so it will emit red light.
Handling method: In this case, do not rush to see the line and equipment, should first make a call to the network operator to determine whether the broadband is overdue. If it is caused by arrears, it will return to normal after payment.
Under normal circumstances, if the optical signal of the router has been flashing red, it may be that the network line connected to the router has dropped. You can turn off the power to the router. Turn it on again. The router will reconnect to the network.
The optical signal on the router has been flashing red, you can replace a light cat, so that the broadband network signal is stable, the light cat is used normally. The light signal on the router has been flashing red, indicating that the broadband signal at home has been working normally, if the red light does not blink, it is always on, indicating that the broadband network signal at home is not good. Therefore, the optical signal on the router has been flashing red, and it is OK to replace a light cat.
