Internet access suddenly dropped 20, Internet connection suddenly dropped

Sometimes there are too many packets sent from the outside, and the ARP protection process will occupy the port.

The login server will display: Login server timed out.

Drops naturally. Sometimes the IP is robbed, and the only way to change the IP address is to change it.

If there is no prompt saying that the IP addresses are duplicated, then it is certainly not an IP conflict.

Installing an ARP firewall can only say that you have a certain resistance to ARP attacks, not that you will not fall for ARP Trojans, which are two different things.

Does it show a conflict of IP addresses? You can set the IP to be acquired automatically.

To use a fixed IP, don't use Automatically get IP when setting up IP, click on the next setting, set the gateway, set the subnet mask, and then set the DNS, if you don't understand the gateway, enter ipconfig in the command prompt to view. In this way, the network is more stable.

It should be good now, I don't need to say more...

Like you, I'm a campus network.

There are many ways to do this: check your antivirus first, which can occasionally be a bit conflicting.

Or you should change your firewall, you can choose the firewall in 360 Security Guard, which is quite easy to use; Then there's the fact that someone in your school has a computer that's so badly poisoned, and that's why those attacks are so powerful. However, the reason why you can't access the Internet alone is very simple, that is, your IP is a little problematic, and it is recommended to find a network administrator.

We also use a router in our bedroom, but we all use it to automatically obtain the IP, and after setting the IP, it is also old and dropped, so we don't need it, and we directly make it automatically obtain,

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

1 Check the crystal head of the lower network cable, the crystal head of the ** line, whether there is aging and rust, if it does not work, it will be redone, or it will not have an impact.

2 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).

3 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.

4. 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!!

It can basically be said that it is a problem of network service providers!To put it simply! Because 8-10 p.m. is the peak season! Netcom can't cope with so many people surfing the Internet together! There may be a disconnection!
