LAN master comes in 50, LAN master comes in

It's supposed to be sniffing, right? surfer is also.

Reset the router and see if you can't try another router.

Install Sniffer on a computer directly connected to the router to find network faults.

It is whether your host is connected to the switch or directly connected to the route, if the route is directly connected, see if the crystal head and the routing interface are oxidized. Double-check whether there are strong sources of interference between the network lines, especially the existing accessories of your machine network, such as high-power electrical equipment, especially those with less reliable power outlets, etc

Oh, the network cable of the unit should be connected to the WAN port of the wireless router, if it is connected to the LAN port, it will become a switch, of course the computer connected to the LAN can be used but the wifi is naturally not available.

The steps to set up the router are as follows: first do not connect to the external network, connect a network cable from the LAN of the router to a computer for debugging (optional), set the IP of this computer to automatically obtain, and enter the router for setting. In principle, first set the Internet parameters, select the fixed IP in the access mode, and assign your IP address, that is:

and the subnet mask and the gateway to fill in (in the computer IP attribute can be found in the Internet access), and then set LAN parameters, the key is that the LAN network segment can not be the same as the WAN network segment, according to the external network address you give, the LAN network segment should be set to the above, you can set it to or so on, and finally set the wireless WiFi parameters, use the default settings, change the wifi password. Or follow the router manual to set it up, and then, save it, and restart it!

Turn on the network connection, select "Set up a home or small office network", and then restart it at the end of the next step, turn off the system firewall of the 2 computers after booting, and if there is a software firewall to set a lower setting, (if it doesn't work, turn them off.) The problem does not hit.

Not bad, I hope you adopt it.

The easiest way to do this is to replace the original router with a wireless router. The wireless router must turn off DHCP when it is switched, and of course the mobile phone cannot be used after it is turned off.

If the router is not turned off, the router is connected to the router cascade, and the setting at this time is a little troublesome, which needs to solve the problem that the IP of the WAN port of the subordinate router and the IP of the LAN port are in the same network segment.

First of all, you first determine whether the IP of your unit router and the unlimited router are the same, whether there is a conflict, the general router is, if the unit router IP is, then your unlimited router has to change the IP such as.

In fact, IP conflict is your key....

The router comes out of the switch, and the switch comes out to connect to the infinite router, right? Then go to the second router and set the IP to the gateway of the first router with the IP setting first, and then set the fixed IP to the gateway of the first router. That's fine, the default is to start DHCP.

You need to go to the settings page and click on the setup wizard, and change the dial-up to a dynamic IP!

If you change the IP address, you can't change the IP address, you have a few routers.

There may be an ARP attack, you go to the next color shadow ARP firewall to try.

The community should use optical fiber.

The fiber optic transceiver is faulty. Just find someone from telecom to replace it.

It's not your problem, and there's no way you can fix it.

This problem needs to be further analyzed by checking the ARP table and related log logs on the cell core switching device. The reason for this could be a problem with the switch being used, which is causing this collision domain and broadcast domain.

Simple, 1Network disk independence,It's equivalent to a small computer,Such a device such as NAS,Network storage services,Or a single broken computer is OK,It comes with a Linux operating system,The configuration is relatively simple,Assign an IP of the same network segment,Permission control can be carried out through the web,Look at the manual,A,B has read and write permissions,C,D has read permissions on OK,Only the permission to access the external network is controlled on the router,MAC binding,It is only allowed to bind the computer to the Internet, then bind a, b, then a, b can go online, c, d is not.

2,The network disk is not independent,That is,A,B,C,D install an FTP server SERV U or other similar software,The software itself provides permission control,Build a high-level user authorized to read and write,Build a low-level user,Authorized to read,That person connects all by his own user password。 Or simply don't install anything.,Directly use the way of IP folder sharing.,The permission control is in Windows.,Use the adminstrator user to read, write, delete,Create a guest user is to read.,Think of a lot of ways to do this very flexibly.。

Personally, I think it's caused by your equipment problem or your adsl line coming in abnormally. I also encountered frequent drops some time ago,A lot of people say that there is a machine poisoning in the intranet,I think so,The result is found in the end that the external adsl comes in is not normal,Over the cat stand-alone Internet,Forty minutes will be dropped。 So from my personal experience, I suggest you do the following:

1.Connect the cat directly to an extension of your company for stand-alone dial-up Internet access to see if the connection will be dropped, how long it will take, and whether the network speed is normal.

2.Change to a cat to retest.

3.After there is no problem, it is recommended that you reset the route, restore the factory settings, reset the Internet parameters, and then connect directly to the computer from the LAN port of the router to see if the connection will drop.

4.Connect a normal network cable to the switch in your computer room, and then connect only one computer to the switch to see if you can access the Internet and whether it will drop.

5。Change to a new switch and retest.

After these steps, you can determine what the exact reason is, and I hope you can help this friend. I'll be interested in your results.

Personally, I feel that it is not an ARP virus, it is a hijacking network for its own packets, and it is impossible to break the entire network. One possibility is that there are multiple people using personal routes under your organization's LAN, and there is a conflict in the settings.

There may be attacks in the network, so add them one by one. First bring one and two sets, and then add one by one.

Poisoned, there is computer poisoning in the local area network, forming a network storm. Try it out with 360 Security Guard ARP Protection.
