Why can t even the campus network be connected sometimes?

There is a conflict with the network IP address.

This can mean that the broadband or other Internet access you use is through the router.

In that case, there is an IP allocation problem, if your router is set up with DHCP to automatically assign IP addresses, then all your other connected computers only need to set up automatic IP addresses, and this situation will not occur again.

This will happen if there are computers in the network that manually specify the IP address. In that case, you can change the IP address at once and the problem will be solved.

Of course, the school's network cannot be used exclusively for you alone, and if the IP address you set is the same as someone else's, it will prompt conflicts.

You can change the IP address, only the first line, not the second or third line.

You can write down the IP and change it to automatically get the IP, no, setting the IP can basically solve the problem.

IP conflicts, you must not be able to access the Internet. When there is no conflict, the bandwidth is too small, which will also affect the Internet speed, which is very slow, and it seems like not being able to access the Internet.

The most common virus in the campus network is the ARP virus, which deceives users by sending a large number of spoofed packets, paralyzing their network, and at the same time, your computer is misreporting IP conflicts because it is being spoofed, which was very rampant when I was in school.

First, use the latest version of antivirus software to kill the virus on your computer to prevent your machine from sending active attacks, and then search for AntiARP, which is a professional ARP firewall to defend against attacks.

There is a conflict with the network IP address. "You change your IP address again, someone is stealing your IP!

Maybe it's because there are a lot of people who get off BT in school...

Prone to this problem... In addition, the school campus network is inherently very unstable.

Why is the campus network connected, but it can't be used?

The reasons why the campus network shows that it is connected but cannot be connected to the network are: 1. Network failure. 2. Equipment failure.

Solution: 1. Turn on the mobile phone to start the wifi, select the name of the campus wifi, and click to connect. 2. After connecting, the login authentication page will automatically pop up, please click.

3. This is the page that is out of order. 4. Open the browser that comes with the phone, and enter the numeric IP address in the ** column. As soon as you enter the number part, you will be prompted to log in to the window.

5. At this time, a new login interface will pop up, and if you want to enter the password again, there will be a hint of password on the left side of the login interface. Click Login to go to the prompt login success screen.

In the privacy section, change the use of local mac to use random mac; Click on the wifi details, switch the IP setting from automatic to manual (i.e., DHCP to static), and start to modify; Turn off the wifi and turn it back on; Contact the departments of the complex campus network on campus.

The problem that the campus network cannot be connected, but usually in the following two situations: Unable to obtain the IP address; You can't get out of the authentication page (connected, but can't access the internet, you need to log in to authentication) (the wifi status will tell you which one it is). Workaround:

Target: Method 1: Change the use of local MAC to the use of random MAC (switch between them) in the privacy column.

Method 2: Click on the wifi details, switch the IP settings from automatic to manual (i.e. DHCP to static), start to modify, the following provides a modification scheme, IP address, sub-off mask if needed), router, if there are other defaults, store, reconnect. Disconnect again, switch back to automatic (DHCP), and reconnect to the campus network.

For the first case: you need to know the IP address of your campus network, and manually open the authentication page from the browser. In addition, the easier way is to turn off the wifi and turn it on again, or turn it off and on again.

If none of the above methods work, you will need to contact the department in charge of the campus network of the school.

Problems with network settings:This is often the case when you need to manually specify an IP, gateway, or DNS server.

In the mode of networking, and use the ** server.

Internet. Double-check your computer's network settings.

Network firewallsQuestion:If the network firewall is not properly configured, such as the security level is too high, IE is accidentally put into the block access list, or the firewall policy is incorrect, you can try to check the policy, reduce the security level of the firewall, or simply turn it off to see if it returns to normal.

Precautions for using the campus network.

Please make sure that the network cable from the wall socket to your computer, if your computer is connected to a router, please also make sure that the network cable routed to the computer is connected correctly (or power off the router and restart), if the network cable is not in good condition, you can use a network cable with no quality problems to connect.
