What s going on with the LINK light flashing on the ADSL client device? Can t connect to broadband?

First of all, check whether the crystal plug of the network cable is loose, click on the computer, then open the device manager, find the network adapter point to deactivate, and then start it, it may be fine. If not, don't be angry! Sit back and have a cup of tea In the hot summer, the temperature is very high, don't you feel hot?

Devices (devices are: cats, routers, network switches, Hubble, computers, etc.) also feel hot and can't work; You may wish to refer to the following methods and adopt measures that you feel are acceptable to reduce the temperature of the working environment of the equipment. a：

Users who often surf the Internet for up to half a year should open the shell of the equipment after the power is off, and clean up the dust in the equipment b: Place the equipment in a safer place for people, open the lid of the equipment, and use air convection to strengthen the contact surface with the air for natural heat dissipation; c: Install a micro fan to the equipment to increase the convection of air and force heat dissipation; d：

If you are doing IT, I suggest that you install a heat sink on the heat-generating part of the device after disconnecting the power supply. e：

After the equipment is disconnected from the power supply, use a 3mm drill bit to drill many holes in the upper and lower parts of the equipment to strengthen the air convection flow and improve the heat dissipation conditions; f: To ventilate and dry the equipment, it is best to make an insulating bracket to support the equipment for natural heat dissipation; G: Remove the garbage fragments and IE caches generated by the Internet in time, and organize and run the C disk regularly, which can appropriately improve the running speed.

H: Let the adsl cat sync first: power off the cat and restart it.

i: The software settings are reasonable, so that 3 do not install: do not install informal software, do not install P2P (occupy resources) software, and do not install infrequently used software.

Turn off all unnecessary network connections, such as Thunderbolt BT Donkey, etc.; j: Optimize the network Personally, it is recommended to use some gadgets such as Super Bunny, Optimizer or 360 and so on K: The computer should install at least one effective and genuine antivirus software L:

NIC problem: The NIC has the appropriate bandwidth and works stably. As long as you do a good job in the above aspects, your failures will be eliminated; Thank you for my answer!

Thank you: friend!

The link light is flashing, which means that the modem has been connected, but it can't be connected, it should be a line problem, a quality problem, and you should report for repair.

Go into the route and take a look, see if the pppoe dialing is disconnected, and you can understand it at a glance. If the ISP is normal. There are generally two possibilities in this situation, first, the cat is aging and does not work properly, and second, the router is faulty and the dial-up function is disordered.

It is recommended to observe, with experience 80% is the cat's business, it is recommended to replace!

The router adsl light keeps flashing and can't access the Internet Reason: The router has no dial-up.

Computer enters the router]:

1. The computer IP and DNS settings are automatically obtained.

2. Open the browser, enter the general router address in the address bar is this or check the login information on the back of the router) Enter the route - enter the user name and password, (the default is generally admin).

Set Router Dialing]:

1. In the [Setup Wizard], select [PPPoE Dialing] (some are ADSL dialing), enter the username and password (provided by the network service provider) according to the prompts, and save.

2. In [Network Parameters] --WAN Settings], select [Normal Mode], and select [PPPoe Dialing] in the three options of [Connection]. The next step is to select [Auto Connect], Save, and Exit.

If a broadband fault occurs, you can use the following methods to troubleshoot the fault:

1 Use stand-alone dial-up, if you are using a router, please temporarily disconnect the router for testing;

2 Restart the modem and the computer;

3 Re-create the broadband dial-up connection and try to dial again. How to do it: Start the Program Attachment Communication New Connection Wizard.

If the self-troubleshooting still does not recover, you can log in to the mobile phone business hall Customer Service Broadband Fault Report for feedback, and we will get in touch with you as soon as possible.

1 All If the CD indicator or Link indicator keeps flashing, it means that the communication signal on the current line is unstable, and if it returns to normal after a while, it means that the indicator flashing state is caused by the internal line adjustment of the telecom company.

If the indicator keeps flashing and cannot be returned to normal, it means that the communication line is really faulty. At this time, you can test whether there is a signal in the ** line, there is a signal that the line is working normally, if there is no signal tested, it indicates that the line may be short-circuited or broken, then you must ask professional maintenance personnel to help you repair the line fault.

If the indicator is still flashing all the time when there is a signal on the ** line, it means that there is a problem with the port. At this time, you can check whether the separator that must be used for the ADSL line is connected when entering the home. Before the separator, see if there are other devices connected, such as an extension or an anti-theft system.

There are 2 situations when the DSL light flashes, one is slow flashing and the other is fast flashing. Slow flashing means that you can't connect to the server (i.e., the telecommunications office); A flash indicates that a server is being connected. If it flashes frequently (fast or slow), it is probably a device issue.

Check the **line, play a ** to listen to whether there is noise, if there is, then see which is the poor contact or the aging of the line. If not, check whether the network cable connector, ADSL, and network card are normal. If it's all normal, then you can call ** to the telecommunications bureau to see if it's a server problem.

This can also be caused by the large amount of data exchanged.
