Please help me analyze the problem of the router connecting to the campus network???

Hambeen says Apparently excluded by Mac! What is the meaning?

This is because someone in your router's higher-level network has used an ARP attack to attack your router. The IP that attacked your router is, I'll give you an example of an ARP attack:

Your higher-level gateway is, your router wants to surf the Internet, it must pass the request to the gateway, and your router does not know the MAC address of the higher-level gateway before communicating with the gateway, it will broadcast and issue an ARP request: who is ?Then the higher-level gateway will receive it:

At 00-E0-21-52-54-51 tells you a MAC address, and your router can communicate with the gateway. But here's the problem: if there is a computer with ulterior motives at this time:

Also a at 00-1e-ec-60-52-b0 then your computer will update the original correct one after receiving this. In this way, all the traffic of your router will run to the computer at 132 (because the MAC is his) so that if he wants you to access the Internet, he will go to the gateway on your behalf, and don't let you go to the Internet, just throw away your data. And it can also count your traffic, which is the specific process of ARP attacks.

How to solve it, you need to find a way to get a correct gateway MAC and then bind it to the gateway IP so that your router does not need ARP query for the first communication. Directly to the gateway too. You see your status is unbound.

Let's get it right. What is shown above is wrong!

According to the picture, it is obvious that it was attacked by ARP. It has nothing to do with the broadcast storm.

Apparently excluded by Mac!

There is an ARP virus or broadcast storm in the campus network.

The route is constantly impacted, causing the route to be disconnected.

If you have the option to suppress broadcast storms in the route, you can enable it, and then install ARP Firewall on your computer.

If the campus network is unstable, your route will also be disconnected.

You can contact your school administrator and ask them to take care of it.

Summary. Hello dear, happy to answer for you. Which god will engage in the campus network My router can't connect to the campus network Tengda.

The problem may also lie in the setting of the router: It is recommended that the general router can go online directly if the dynamic and static dialing is successful. Unless the main interface is set. But the main interface will definitely not set up the login screen of Tengda.

If there is no connection to the network (static or dynamic dialing failure), the router settings interface will be jumped, and the network connection fails, please set the network from the new. You can take a look at the connection status on the router interface, and it must be not connected.

Hello, I have seen your question and am sorting out the answer, please wait a while.

Unless the main realm megacrack is set.

But the main interface will definitely not set up the login screen of Tengda. If there is no connection to the network (static and dynamic dialing failure), it will jump into the router setting interface, and the network family is trapped and the connection fails. You can take a look at the connection status on the router interface, and it must be not connected.

Hello dear, happy to answer for you. Check and confirm the login address of your router first. You can check the login address (management address) of this router on the nameplate of the bottom world of the route search machine

Hello, I have seen your question and am sorting out the answer, please wait a while.

In order to prevent the phenomenon of multiple uses of one number for students, the general campus network does not allow the use of routers or software. How does it do it? The analysis is as follows:

When using the client dial-up directly, as a user, you may only need to enter the account and password, the key is in the dedicated client, not only the username and password but also other parameters transmitted to the authentication end, only the data that conforms to this format can be authenticated;

When using a router to dial up, it can only transmit the username and password without its special data, so it cannot be authenticated, so it is impossible to connect to the Internet using the router's WAN interface;

Not only is the router unusable, but when the client has multiple network cards turned on at the same time or has **server software, the authentication client will detect these applications and prompt you to close these programs, and you will not be allowed to access the Internet. This prevents you from having one multitask.

If you look through the routing table, you will see that the IP trace will also see how many routers you pass by.

A brief summary of the downstairs owner's problem:

1.Can a router access the Internet with one router shared after DHCP is enabled?

2.Will DHCP be Affected on the Router?

2.It's possible.

Detailed answer: The function of DHCP is to automatically assign IP addresses, if the campus network that automatically obtains IP addresses is assigned by the DHCP of the network center, if there are multiple DHCP in this LAN or virtual LAN, and the network center cannot control it, then the user may obtain an illegal IP address (not the address assigned by the DHCP server in the network center). The DHCP service sends a broadcast to the network when the computer is turned on, requesting an IP address, so that all DHCP servers in the network can receive it and respond to it.

Whoever responds first will be assigned an address.

So whether you can share the Internet through the router, this question depends on the specific network structure and the degree of management authority. Not absolutely, not necessarily impossible. But judging by the landlord's description, your method will not work.

If you're using a campus network, you basically won't need a router right now. Die hard, the easiest way to share is to install connectivity on your laptop.

It's true, it's true.

The internet in the classroom is not authenticated, and you can connect to the teacher and you can wifi

You can even connect the dormitory, but you have to pay for it. Crack it at night.

After looking at your question and adding, there is no problem with the line connection. Here's what you need to do:

1. Don't connect the network cable from outside. Only connect your router to the LAN port of your computer.

3. Click on the WAN port settings, and set the WAN port connection type to a static IP (see clearly: it is not PPPoE, but a static IP, and the IP address is filled in with the IP given to you by the landlord).

4. If your computer is set to automatically obtain IP addresses, click on DHCP server and turn it on. If your computer is specifying IP addresses, set the IP address range to between.

5. After setting up your router, connect the WAN port of your router with the cable from the landlord, and you can surf the Internet normally.

Theoretical basis:

The analysis of your specific situation is that the signal entering through the WAN port is then converted into a wireless channel [multipoint] and a wired port [4 points] through the router.

2. LAN and WAN are generally not in the same network segment. Then you can change the IP address of the LAN at will. Usually yes, that's fine.

3. Wireless general setting back encryption.

So the steps you have to do::

1. Put the router rest, that is, poke the hole behind the router for a few seconds, and then you can reset the factory settings.

2. Don't connect to the external network first, but connect the router to your own computer. The computer can be set to "automatically obtain IP address" or: [the same network segment as the factory IP of the router]. Enter the router.

4. The IP address of LAN will automatically exit after being changed, and you will have to re-enter the router [You must restart the computer first and release the original IP address before you can enter the router again.

5. Set the WAN mode to "static working mode", and change the IP address of the WAN port to the IP address given by the landlord.

6. Enter the wireless column and set a password for wireless transmission. WPA encryption is generally chosen.

The other points that are also spoken upstairs are connected

Change your router's WAN IP address to something else without changing it, and you're good to go.

Enable the DHCP service and enable automatic IP address assignment on your mobile phone and computer.

Configure it the same way as if you had a line, and then turn on the wireless function. If you want to encrypt, just follow the prompts to set it up step by step.

Network operators in different regions and campuses adopt different router restrictions, so you can ask your brothers and sisters for details. If you have unlimited wireless routers, you can use it.

How to configure a wireless router for campus telecom broadband:

1.The router is connected to the campus network.

Connect the campus network cable to the WAN port of the router, and use the network cable to connect the computer to any LAN port of the router. When the LAN port flashes when the computer is turned on, it means that the computer has successfully established communication with the router.

2.The system is connected to the router.

Turn on the wifi of the computer, search for the default wifi name of the router (the nameplate on the back of the router is written), and connect to the wifi network. The first time you use the router, you generally don't need to enter the wifi password.

3.Go to the gateway page.

Open a computer browser and enter the gateway IP address of the nameplate on the back of the router (generally, enter the gateway configuration interface. (This interface will pop up automatically for new routes).

4.Set up a way to access the Internet.

Go to the WAN port settings in Advanced settings. If the broadband service requires dial-up, select PPPoE dial-up, otherwise you can choose DHCP to get automatically. To dial up PPPoE, enter the broadband password, and select Automatic connection as the connection mode.

If DHCP is automatically obtained, you do not need to enter this field.

5.Set the wifi name and password.

<> go to Wireless Security in the wireless settings, select WPA2-PSK mode for security mode. Select AES for WPA encryption rule. Set up a wireless network key. The router will automatically restart after setting, please enter a new wifi password to connect.

6.The configuration is complete and you can enjoy the network.
