Low voltage causes wideband ADSL cat to restart, what to do

I've been suffering from disconnection for some time now!

The voltage in the community is unstable at night, the light is dimmed for a few seconds and then returns to normal (or becomes brighter at once), and then the line drops, dozens of times a night, and it is useless to install a voltage regulator, which is almost crazy!

I checked a lot of information, and today it was finally solved!

I first found an old desktop power supply in the unit, (I used a notebook), and then bought 4 diodes, connected in series on the 12V yellow line of the power supply (my cat and router are both 9V, and 12V will be reduced to about 9V after series connection), cut the adapter power cord of the cat and the router, and connect them to the 12V (already 9V) yellow line and black line of the desktop power supply, and connect the desktop power supply to the voltage regulator for the sake of insurance.

So far, there has been no disconnection, the voltage of the post has been lowered several times, and the electric fan has stopped almost without dropping.

I hope it helps you, if you use a desktop, it will be directly connected from the power supply in the case.

It's good to add a voltage regulator to the cat, the laptop is not used, and it has nothing to do with the cat's power adapter.

Buy a corresponding output voltage and current switching regulated power supply for cats, which can generally ensure the output of stable voltage on the occasion of 100-260V, and this product can be bought for about 20-30 yuan.

Sit down, drink a cup of tea, cheer up, and process your computer according to the following requirements, which will definitely help your computer to run.

It's a hot summer, the temperature is high, don't you feel hot? Devices (devices refer to: cats, routers, network switches, Hubble, computers, etc.) will not work if they feel hot; 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 device after the power is off and clean up the dust in the device.

b: Place the equipment in a safe 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 you: after disconnecting the power supply, install a heat dissipation front plate on the heating parts of the equipment.

e: After the equipment is disconnected from the power supply, use a 3mm drill bit to drill many holes up and down 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;

H: Let the adsl cat sync first: restart the cat after powering it off.

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!

1) First of all, troubleshoot the disconnection caused by PPPoE protocol problems, if you are using Windows XP operating system, install system security patches, and then re-establish the dial-up connection; If it is not WindowsXP to operate the pin limb celebration system, reinstall the PPPoE number program, and then re-establish the dial-up connection, and then check whether the fault disappears. If the fault is solved, it is the operating system and the PPPoE protocol that cause the fault.

2) If the fault persists, check the ADSL next

Whether the various wires of the modem and the separator are in good contact. If the contact is good, then check for ADSL

modem or not. If it overheats, adsl

The modem power is turned off and placed in a ventilated place to dissipate heat before use.

3) If adsl

If the modem temperature is normal, then use the substitution method and use a good ADSL

The modem and separator replace the original ADSL

modem and separator to see if the fault disappears. If the fault goes away, it's ADSL

If the modem or separator fails, it can be replaced.

4) If the fault persists, in the "System Properties" dialog box that opens, click the "Hardware" tab, click the "Device Manager" button, and check whether the "Network Adapter" is selected. If so, remove it and then reinstall the network card driver. If not, upgrade the driver of the network card and see if the fault goes away.

5) If the fault goes away, it is a problem with the network card driver. If the fault persists, use the replacement method to check whether the NIC is normal. If not, replace the NIC.

6) If the fault persists, then check whether there are large transformers or high-voltage lines around. If there is, it may be caused by electromagnetic interference and frequent dropouts. Shielding the ** cable and the Internet connection cable.

7) If there is no hunger around, there are large transformers or high-voltage lines. Then the ** line passes through the place and adsl

Stay away from cordless**, air conditioners, washing machines, refrigerators, etc., to prevent these devices from interfering with ADSL

modem operation (it is best not to share a power cord with the above equipment) to detect whether the fault is troubleshooting.

8) If the fault persists, you can check and kill the virus or reinstall the operating system, which will also cause frequent disconnections.

9) If the fault persists, it may be the ADSL line fault, and the telecommunications bureau can check whether the residence is more than 3000 meters away from the local computer room.

It's the same as what I've been going through in the past few days, and it's only been done for me today. Last week, when the situation you mentioned began to appear, I called ** to Telecom 10000 and reported a broadband failure. It's good to be good after Ha, I've been down since Monday, and today I came to dismantle Zheng Ji and changed the line for me (that is, the line that is connected to your house ** outside), it's good!

I think the situation you said is the same as mine, or it may be my situation, you just call ** and ask your broadband provider to replace the offline line for you!

Hope it helps!

It could be that the data center of the telecom is limiting your switches. Because of the fierce state, it is unwilling to let you share 4m with too many people! He has a lot less income!

It's also possible that the bandwidth permissions of your joke account have been changed! I tried 4m to be limited to 1m, hit 10,000 and make a big noise, and it was OK immediately!

Hello! According to the analysis of the problem you described, it is not the adsl cat restart, the problem is the network disconnection.

1. Carry out comprehensive anti-virus on the computer, and viruses can cause the network to be disconnected.

2. 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.

3. The heat dissipation of the ADSL cat is not good, so you can change it to an ADSL cat.

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

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

None of the above methods can solve the problem, directly call the ** repair of the operator of the wide escort Xiang digging belt, and ask them to help you slow down the treatment.

You first 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, maybe it's fine. If not, don't be offended! Take a look at the following methods, you may wish to use measures that you feel acceptable, and thoroughly organize your love machine, and you will not have this kind of phenomenon.

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 internet connections, such as Thunderbolt.

BT donkeys, etc.; This answer belongs to the "harmonious" individual, and it is shameful to copy

j: Optimize the network.

Personally, I recommend using some gadgets.

For example, Super Bunny, Optimizer or 360 and other k:

The computer should have at least one effective and genuine anti-virus software installed, and the firewall should be set up appropriately (not too much, too high).

l: NIC problem: The NIC bandwidth is appropriate and the operation is stable.

As long as you take care of our brothers (routers, cats, Hubble, network switches and their computers), our brothers promise to truly do: "You respect me, I respect you" for your faithful service. Otherwise, ride a donkey and read the record book--- let's see!
