If you are always disconnected from the Internet, please answer the expert, and the Internet is alwa

There are two possibilities: You judge according to the actual situation: 1: The problem caused by the LAN virus ARP solution: you go to the next 360 security guard, there is an ARP firewall in it, 2: That is, your city blocks the router to share the Internet, because you are handling a personal ADSL.

I've encountered a lot of problems with you, the same problem, the land game has been used for a long time, and the chip will be like this once the heat is too high, I have helped the company to change the land game a few times, and it will not be replaced if it is replaced, because the network cable will not have problems except for being bitten by rats! Changed the bag!

Old-fashioned. It could be an ARP attack. You go to the next ARP firewall. Maybe it helps.

The 4th floor is right. It's arp...

Someone in one of your four machines has been poisoned.

Causing an impact on other machines.

It is good to equip an ARP firewall.

I think it's important to find out which one was poisoned.

The ADSL light flashes to indicate that the wideband signal is unstable. There could be 2 reasons for this:

One is that the power supply of cats is insufficient, many cats are powered by very heavy transformers, and the output voltage is insufficient when the mains voltage is low, resulting in cats not working properly. The solution is to change the cat to an electronically regulated power supply.

The second is the problem of broadband lines, the line between the service provider and you plus is aging, the distance is too far, and there are interference signals in the middle. You need to contact the broadband service provider to solve this for you.

If there is a problem with the device status light, ADSL and INT light are off, it may be a problem for the cat, you can find the operator to replace the cat to see.

Hello, you said that this situation is generally caused by carrier lines, cats, routers, etc.

1 The cat has been left open for a long time, it is very hot and hot, it is recommended to place the cat in a ventilated place as much as possible, and do not overlap with the router. so as not to overheath the temperature. It's really not good to recommend changing a cat with good performance (I hit ** to go to telecom, free to change).

2 Several computers share the network, because the router is too poor, others use P2P to watch movies, etc., it will drag the router to death, restart the router will be better, the long-term solution is to change to a better enterprise-level router.

3. The operator's computer room is far away from your home, beyond the ADSL distance, line failure, etc., then ask them to measure the signal strength and line situation (sometimes two lines, one can be connected to the Internet if one is broken, but the network speed is slow, easy to drop, ordinary people can't find it).

Please find the problem from the above points, I hope it can help you!!

I don't understand hi me, I can teach you to analyze and solve it step by step!!
