How to solve the red dot on wifi?

Causes and how to fix them:

1. The optical signal of the broadband network connected to the computer shows a red light, which obviously prompts the user that the broadband network is disconnected, resulting in a red indicator display.

Solution: You only need to restart the connection of the optical modem device to restore the connection of the optical signal of the broadband network.

2. The router optical signal flashes red, which is generally due to too much optical fiber loss, which will cause delay or interruption.

Solution: Report for repair, to detect the optical fiber line (including pigtail), the mobile phone is unstable can only mean that the router signal is not good, if the connection near the router is still unstable, then it is very responsible to tell you that the router also has a problem, try it yourself. A wireless router is a router that is used for users to surf the Internet and has a wireless coverage function.

A wireless router can be seen as a device that sends broadband network signals from the wall of your home to nearby wireless network devices (laptops, Wi-Fi-enabled mobile phones, tablets, and all Wi-Fi enabled devices) through the antenna.

Popular wireless routers on the market generally support four access modes: dedicated line XDSL cable, dynamic XDSL, and PPTP, and it also has some other network management functions, such as DHCP service, NAT firewall, MAC address filtering, dynamic domain name and other functions.

The signal range of a general wireless router is 50 meters, and now some wireless routers have a signal range of 300 meters.

If the optical signal light turns red or flashes, it means that the optical fiber signal cannot be received, which is usually caused by the following conditions:

If there is a problem with the optical interface of the optical modem, you need to replace the optical modem.

The indoor pigtail connection optical modem connector is loose, and the connector can be restored by plugging it in;

The bend of the optical fiber in the indoor part is too large. Excessive bending of the optical fiber will affect the total reflection transmission of the optical signal in the optical fiber, as long as the optical fiber is straightened;

If the outdoor optical fiber is broken or the optical port of the equipment in the equipment room is faulty, you need to contact the staff to report the fault.

If there is such a problem, it is a failure, it is best to put it, wifi is turned off, and then wait for two or three minutes before restarting, generally speaking, it will return to normal, if it has not returned to normal, you can check whether the broadband in the home expires, if it is normal, or there is a red dot, then you can change a router.

Restart the network, if it still doesn't work after restarting, it is recommended to contact the network company, it should be a problem with the network

You can try restarting a few times, and if that doesn't work, then ask someone on the server side to help.

Summary. Hello wifi shows that the light signal red dot is generally.

1. Arrears. If you find that the optical modem routing all-in-one provided by the network operator emits red light, you can try to restart the device or turn off the power for 3 to 15 seconds before restarting it.

What to do if wifi shows a red dot on the light signal.

Hello wifi shows that the light signal red dot is generally.

1. If you find that the optical modem routing all-in-one machine provided by the network operator emits red light, you can try to restart the liquid backup or power off for 3 15 seconds before restarting.

If the balance is already in arrears, you can pay the loss and roll fee through the network or offline business hall, and you can open it after payment. However, it should be noted that after payment, the device needs to be restarted before it can be used normally.

Second, there are many indicators on the external line faulty optical modem, if the indicator light that emits red light is marked as "LOS" below, it means that the optical fiber line is out of the finger good limb fault or the optical fiber port is closed. There are two types of optical fiber ports that are closed, one is the first type of "broadband arrears", and the other is caused by the misoperation of network operators' customer service, but this probability is extremely low.

If this is the case, it is not a problem with the user's indoor equipment, you can call Unicom Humai customer service **, confirm the repair time, and after the repair is completed, the network will return to normal.

3. In addition to broadband arrears and optical fiber line failures, there is also a situation caused by the failure of "optical splitter".

When you encounter this kind of problem, you can't solve it yourself, you can contact the designated maintenance personnel of the potato mountain department to let them come to check the big hand, which is related to the unexpected power failure of the community.

It is also possible that the optical catroad is good to connect the interface between the all-in-one machine and the optical fiber, and the equipment storage location is vibrated or moved, which will cause the interface to be disconnected, you can try to plug it in and unplug it again, connect the power cord, if it is not good, you need maintenance personnel to take the professional equipment to the door to re-weld.

Dear, I'm glad to answer for you: How to solve the problem of the wireless network flashing red dots Answer: Reason 1:

The connection between the optical fiber pigtail and the optical fiber coupler is disconnected, that is, there is a problem with the optical modem and the optical fiber connection, although the staff is still checking the connection when it is installed, but after a long time of use or human factors. Solution: Try to reconnect the pigtail, do not use too much force, it is easy to cause the fiber to bend and break.

Reason 2: Because the materials that make up the optical fiber are glass and plastic, the optical fiber is very easy to be damaged and broken in the state of bending and extrusion. Workaround:

The general optical fiber damage and fracture is not able to see the obvious scars, and the use of the world can not be repaired by themselves, it is recommended to immediately call ** to find broadband maintenance personnel, optical fiber fracture repair is very convenient, and very cheap. Question 3: If the optical modem fails, the probability of this kind of failure is still very small.

Dear, hello, I'm glad to answer for you: What to do if wifi displays a red dot of optical signal Dear, hello wifi displays a red dot of optical signal Reason: There is a problem with the optical interface of the optical modem, and the optical modem needs to be replaced; The indoor pigtail connection optical modem connector is loose, and the connector can be restored by plugging it in; The bend of the optical fiber in the indoor part is too large.

Excessive bending of the optical fiber will affect the total reflection transmission of the optical signal in the optical fiber, as long as the optical fiber is straightened; If the outdoor optical fiber is broken or the optical port of the equipment in the equipment room is faulty, you need to contact the staff to report the fault. Wi-Fi (pronunciation: wa fa, French pronunciation:

WiFi), also known as "mobile hotspot" in Chinese, is a Wi-Fi Alliance manufacturer's verification trademark as a brand certification of products, is a wireless LAN technology created in IEEE standards. Due to the close relationship between the two systems, Wi-Fi is often used as a synonym for IEEE standards. "Wi-Fi" is often written as "WiFi" or "WiFi", but they are not recognized by the Wi-Fi Alliance.

Not every product that matches the IEEE applies for Wi-Fi Alliance certification, and a product that lacks Wi-Fi certification does not necessarily mean that it is not compatible with Wi-Fi devices. IEEE devices are installed in many products on the market, such as personal computers, game consoles, *****, smartphones, tablets, printers, laptops, and other peripherals that can be used to access the Internet wirelessly.
