How to check if your network cable has been divided by others?

If the home network cable is directly connected to the computer, it will not be separated, and if the home network cable is connected to the computer through the router, it may be separated from the router. Just look at the connected devices on your router.

How to check the number of people sharing Wi-Fi:

1. When the computer is connected to the Internet, open the browser;

2. Enter " in the address bar and press Enter (most routers enter this string of numbers, and some routers of other brands enter other numbers, such as Xiaomi routers, please refer to the router brand and manual for details);

3. Take the TP-Link router as an example, enter the user name and management password (the default user name and management password are admin, if the router has been changed at the beginning, please fill in the management password that you have changed);

4, in"DHCP services", in the Client List, you can see how many devices share the network.

If someone steals the network cable, you also need your broadband account and password to connect it first. Are you using a router or do you have to connect every time you turn it on?

adsl bar If you have an account and password, it will not be stolen It is your own line problem Call ** to telecom Call them You don't have to worry about it. Money is always to be served, be bold.

1.Don't worry, if it is a network cable, you can use a line tester to test that the light from 1 to 8 is intact, if it is 4578 that is not lit, then you have to consider the problem of other people's private connection. 2.

In the extreme, if someone adds a switch to you in the middle and then distributes it to you, then you can solve this problem by manual dialing, and he can't divide your network speed. If it's the ** line, if someone else occupies it, then you can't get on the network, if the network speed is slow, you should first check the line connection, joint oxidation and do a computer optimization operation, clean up the garbage, reduce the computer boot loading items are good. There will be some improvements.

Contact your broadband provider and they can help you look it up.

How can I know if the network cable I surf the Internet has been divided by others:??

Hello, dear, there are two situations: 1. If you use a wireless router, you can check whether the IP connected to the router is your own when you feel that the network speed is low, if it is not your own, or you only have two computers connected to the wheel, but there are three IP addresses on the router, someone must have stolen your network. 2. If you don't use a wireless router, you can correspond to the corresponding rate package according to the megabyte of your own broadband, and when you feel that the network speed is low, use the network speed tester to measure your rate to know if someone has stolen your network.

Problem description: If someone steals my network cable, how can I find out about him?

LAN Assistant (lanhelper) is a software that will meet your needs.

1) Powerful scanning engine, can quickly obtain the host name, workgroup, IP address, MAC address, shared folder, shared printer, hidden share, shared folder whether the shared folder is writable or password protected, system (Windows) version and other information, can scan the entire LAN or specify multiple workgroups according to the workgroup, or specify an IP range to scan the network.

2) Wake up the remote host. After scanning to get the MAC address of the other host, you can wake it up when the other party is powered off, provided that the other party does not disconnect from the power supply.

3) Remote shutdown and restart. You don't need to install any client programs on the other party, as long as you have the appropriate permissions, you can shut down or restart the other party's computer through the network.

4) Send various messages in the local area network. There are multiple ways to send to multiple hosts or workgroups in a list box, to an entire LAN, and so on.

5) Fully use multi-threaded technology to rewrite, multi-threaded concurrent scanning, the speed is greatly improved than the previous version. (6) Use XML to save or display the scan results, and the scan results can be directly opened in the browser in the form of sorting ** after processing the XML style sheet XSL, which is convenient for viewing.

Moreover, when you go online or play **, it is impossible for his cat to connect.

That is to say: it is a modem, and there must be a series of connection protocols, even if he is connected to a physical protocol, he needs to be authenticated and use a password to access the Internet.

If your network is connected to your home with a network cable, it can't be stolen. The network cable is two pairs of twisted pairs together. If you don't need to connect it with a dedicated connector, it will change the performance of the transmitted signal, and you can't connect it at home, and of course he can't connect it either.

Even if you can connect to a NIC, the NIC does not report an error. The network cable is also not allowed to be connected in series, the network cable is the port of the network card and the switch one by one, and it is a pair of MAC addresses to learn from each other.

In principle, it is impossible to be secretly connected, so you don't need to know if your home's network cable has been secretly connected.

There is only one possibility of being stolen, he added a hub (hub) or small router in the middle, from 1 network cable to 2, if your account is not leaked. It is also impossible for him to use your account to access the Internet, and the smallest hub is 10m sharing, and it will not affect the speed of your Internet access, and the connection you use the Internet is generally 2M.

I am the deputy senior engineer of a branch of China Telecom, and I will answer you as a user of Telecom.

Thank you! I've been worrying about this for a long time. Because I once encountered a cable TV line at my home that was connected to something.

It is not ruled out that he is tinkering with your network cable. But it won't work, so rest assured. If your cord is broken, you can call ** for repair.

There are various possibilities for slow internet speeds, and I can't guess this. The rental house and you use the network cable, that is, you have to install a router in your home and share the bandwidth. You're better off refusing.

Because, sharing a bandwidth with others will definitely slow down your internet speed. And telecom companies don't allow individuals to share networks with each other. Cyber regulations also don't allow it.

It is impossible to secretly connect network cables, because there are now three broadband connection methods: ADSL, community metropolitan area network broadband, and optical fiber exclusive.

If these three methods are secretly connected from the connection line, the real owner's home will definitely be disconnected and discovered by the owner.

The so-called network cable stealing should be commonly known as rubbing the network, that is, the owner uses a router at home, and the protective measures are not in place and the password is cracked by nearby people, so that the network is rubbed.

If you want to check whether the network is rubbed, you can log in to the router and enter the ARP mapping table (the router is different, the interface is not the same, but the functional modules are similar), you will find all the devices connected to this router, and exclude that the MAC address you know is the device of the network user.

1. Go to the router settings, check the name of the Internet subway machine, traffic and other information, if there is someone else's machine name, you will find it.

2. If he connects to your network and disables the MAC of his network card, he will not be able to access your network.

Go to the router settings and check the name of the Internet subway machine, traffic and other information.

You really don't have to worry about this, first of all, most of the network theft is to steal the wireless network, the wireless password is cracked to steal the network, wired network theft is unrealistic, because the cat and the router are installed in your home, if he steals your network through the network cable, (1, connected to the cat, this must be in the case of knowing your home broadband account password. 2. Connected to your home router, this does not need to know your home broadband account password). You have to know where all the network cables plugged into your router, and which one you don't need to pull out at ease.

Your question is not detailed, could you please add, is the person who repaired it close to you? Let's say downstairs in you, etc.

There are two scenarios:

1. If you use a wireless blind reputation device.

When you feel that the network speed is low, you can check whether the IP connected to the router is your own, if it is not your own, or you only have two computers connected, but three IP addresses appear on the router.

Someone must have stolen your net.

2. If you don't use a wireless router, you can use the corresponding rate package according to the megabyte of your own broadband, and when you feel that the network speed is low, use the network speed tester to measure your speed to know if someone has stolen your network.

1.Buy a router (if the laptop needs to use wireless Internet access, buy a wireless router) and set the corresponding network parameters;

2.The router is a device that sets up a LAN to achieve network sharing, and the general connection and setting methods are as follows: connect the network cable out of the broadband cat to the WAN port of the router, connect each computer to the LAN port of the router, and the IP address of the computer network card is set to be automatically obtained, enter it in the address bar of the computer browser, and specifically check the network parameters obtained by your computer network card, and log in through the IP address of the gateway) Log in to the router, and the general user name and password are admin, Select the WAN port settings, and set your broadband account and password to the PPPoE mode.

3.If the notebook uses wireless Internet access, the operation is as follows: right-click Wangju online neighbor - properties - right-click wireless network connection - view the available wireless network, click your wireless network name in the searched wireless network - connection, and enter your wireless network key for verification, after passing the verification, you can connect to the wireless router to access the Internet normally; If it is a mobile phone wifi, the same as above, it can also be used after searching for wireless signals and entering the wireless network key connection;

4.Generally, families use routers with wired routers**in seventy or eighty yuan,Wireless routers are**slightly more expensive,Need about 150 yuan noisy,It is recommended to buy network products that use TP-Link or D-Link,Stable performance and high cost performance。

A network cable can only be used by multiple computers at the same time when the router is installed, but you can't see how many computers are in use You can only see how many computers are connected to the network, and under normal circumstances, only the computer that is connecting to the network can be seen, if the other computer is connected to the network cable, but there is no Internet, it can not be found.

First open IE, enter, the username and password are admin, and then select the "Client List" in the "DHCP server".

You can use some small software, like a LAN viewing tool, and so on, if you just look at the DHCP address assigned in the router, you can't see it, because the computer can manually configure the IP address by itself.

If you are owned by the Internet?

You can find out in the next little software! Like cyber scissorhands or something!

No, you can't! Look at what network cables! Telecom is one! Netcom is multi-purpose.

Stolen network cable generally refers to the use of wireless routers to crack passwords to rub the network. You can log in to the router, check the device connection status, and check the MAC address of the connected device to confirm whether there are any devices that are not allowed to log in.

1. Since you can access the Internet, first log in to your router. Enter it in your browser and log in to the admin page.

3. Know the MAC address of your home device, compare the device MAC in the router to see if it is your own home device. (This is the most accurate, if it is too troublesome, you can turn off all the Internet devices at home, leaving only the computer that logs in to the router, and a MAC address outside the closed potato is the device that rubs the Internet.) ）

4. Take measures to remedy the situation immediately after confirming that someone has rubbed the net

1) Set the wireless wifi password:

There is also an option on the left in the wireless settings, there is an SSID, this is your no thick empty line, there is a password setting after setting, the password is as complex as possible, and it is best to combine alphanumeric symbols.

2) Set a login password.

Change the default admin and admin login passwords to prevent someone from breaking the password and rubbing the network to modify the router for you.

3) There is also a troublesome way to set the MAC of your home device to allow Internet access, so that as long as the device is not in this whitelist, it will not be able to access the Internet through this router.

Click Save and restart, and you're done.

To give you the easiest way to do this, start - run - search limb cmd - enter arp

A on the shirt you can see the IP and MAC addresses of all the machines on the road silver leak by the device except the host is last.

The rest is just other machines.

Let's take a look at how many grandsons you have in your route, and there are fewer machines connected, and I don't usually use P2P terminators.

If you're sure someone has embezzled it, there are plenty of insurance measures:

MAC address filtering, change the wireless security password, change the easy-to-remember SSID and cancel the SSID broadcast, if necessary, change the route to the LAN port address.

Don't use the default one.
