How many computers in the LAN are disconnected and can t access the Internet?

It is estimated that the recent epidemic of the devil wave virus, I have also been hit, the phenomenon of turning on the Internet for 10-20 minutes or longer, the time is uncertain, the network is disconnected, the connection display of the lower right foot is normal, but it can't be opened, at this time you go to the online neighbor to see the connection, it is also connected, but don't worry, refresh it, find that it is disconnected, the connection is useless, it is useless to restart the cat, the restart machine is easy to use most of the time, but it will not take long for the situation to appear again, you go to the next xp patch, I found it on a forum, It should be okay to make up for the restart.,It's not okay to reinstall the system and then turn on the XP automatic update.,But my friend used the automatic update to say,There is always an error prompt when the update is finished.,I don't know how to do it.,My supplement is fine.,It's been a long time.,Mine is Windows XP2 Just this** Go to the next one.。

Good luck

The ultimate solution: switch to a different switch.

Temporary solution: Set the computer you can't access to the Internet to 10M full duplex (don't tell me you don't know what to change).

It's strange.,I have this problem here occasionally.,I'm also looking for a reason.,I can only give a suggestion.,That is, after the computer drops,Restart to go online.,There shouldn't be a situation where you say so.,It will take a few hours to get on.。

It may be that your cat is of poor quality.

Your problem has not been described more clearly.

Change the route, or restart the cat.

It is recommended to change the route.

I guess you are in the dormitory Internet When you hang the wire, not all computers are hung and have tried the above scheme, I think someone occupies a lot of network traffic and causes the network card of other machines to be overloaded, so as to hang the wire, I and my neighbor 3 people use 2m broadband If someone watches QQ live broadcast and someone gets off BT, I will have no network If I force it to use, sometimes it will cause the route of my door to not work properly, and sometimes it will hang the wire.

I think if you try to reduce the use of other networks, you won't be able to hang the wire again.

You first have to figure out what topology your network belongs to There are four types of topologies in the network: bus topology, star topology, ring topology and tree topology If it is a ring and tree topology, their disadvantage is that the failure of any one site will affect the operation of the entire network, and if it is a bus topology, then the failure of the bus itself is devastating to the whole system

Change the route, or restart the cat.

The same happened to the computer in my unit, and I couldn't find the reason for asking the computer company to fix it.

One of the computers must have a virus in it.

I've also asked this question, and it is recommended to change the route.

There should be a problem with the router, it is best to try a new router and switch!

The source of the LAN in the scattered mode computer also digs up the address, directly put the address of each unit as a folder on each other's desktops, so that it is much more convenient to transfer files, even if the LAN can not see the network, in fact, it is also **, does not affect the hail slow transmission.

1.Check whether the IP configuration of the desktop computer is automatically obtained, if so, there is no problem with the desktop, so the reason may be that it appears on the network line, or the configuration (ps: the home can be ignored,,This is nonsense,Don't slap people in the face...。。

2.It is recommended to try a different network cable, and try to connect the desktop computer directly to the cat (ps: you can try the previous sentence).

3.It is recommended to update all the drivers, especially the motherboard, those network devices that can be mobilized, and re-set it according to the setup wizard (ps: I think it is most straightforward to install the system).

4.What's incompatible?? I don't know about this.,,I'm sorry,,The landlord still makes a system to try.,,If necessary, I can teach you how to make a system U disk and install the system.。

ps:This is the situation of the gods,,Please give it a try first.,If it doesn't work, kneel and beg the great god wow.。。。

5.Landlord,You have a bad feng shui,,, although this is a little unpleasant,,There used to be a colleague whose computer was not good at his workstation,To someone else's, it's not good to change a new one,,I have to fix it every day,,, landlord,,You there,,You can change the computer to try! Or try it in a different place (ps:

Don't slap your face when you say yes!!

It may be a loop between wired and wireless network cards, disable the wireless network card when plugging in the network cable, and give it a try.

When the computer is repaired normally, it can only be a problem with your routing settings, the specific information is too little to help you, and then report the telecommunications network failure, and the repairer will ask him to help you look at the routing settings.
