I can t use the Internet when I go home after changing the school network cable

Check to see if the DNS is set, whether the IP address is set, whether the MAC address has been modified, and whether the dial-up account has been modified. You can check it out!!

Have you installed the driver?

If it's ghost xp, please plug it in again.

If the IP is reset, if it is a fixed IP, you can just get the IP automatically.

The reasons why the school network cable is plugged in and there is no network are as follows:

1. First of all, change the router port to determine whether the router port is broken.

2. Change the network cable or use the line tester to test the network cable on-off and the quality of the crystal head.

3. Replace the network card or computer to test whether the network card is broken.

After the above three steps, you will definitely be able to eliminate the fault that the network cable is not connected.

Campus Card Introduction:

Campus cards are divided into temporary and official cards. When the new students registered, most of the students were able to get the official campus card, and a few students were unable to make a card because of incomplete information. Students who have received a temporary card should go to the Campus Card and Fee Service Center of their campus to replace the official card within one month of the start of the semester.

Deposit machine recharge:

The trap storage machine is a kind of self-service terminal equipment of the campus card system, which mainly provides the function of transferring money from the bank card to the campus card, and the trap memory machine can also report the loss and unhang the campus card, modify the campus card password, modify the consumption bending liquid limit, pay the campus network fee, hot water fee and air conditioning fee, etc.

It is worth mentioning that only the debit card of the Bank of China issued by the school can be recharged through the circle storage machine, and the two cards correspond, that is, you cannot use your own bank card to recharge the campus card of others.

At the beginning of the new semester, there will be a lot of students who use the trap machine, so you should pay attention to choosing the time. <>

Hello, it's simple.

First, you swap the new cable with the old one that you can use to access the Internet now. If the computer that has access to the Internet now can't access the Internet. Then you can be sure that there is a problem with the network cable. Check the crystal head.

Whether it is pressed well, or the network cable is broken.

Second, if the computer is replaced, the computer can still access the Internet, and this one can not connect to the new network cable and the other one still can't access the Internet, check the settings between the computer that cannot access the Internet and the by. Including the relevant interfaces and the software and hardware of the computer.

Is it okay to switch back?

You can use Firefox, Window of the World, etc., and if it's good, it's your IE problem.

There may be problems with the network cable.

Is this special line dial-up? For example, PPPoE kind of virtual dialing?

If it's an IP acquisition issue, you can:

Start-Run-"cmd" enter.

Type ipconfig

release.

Type ipconfig

renew".

Wait until you have re-obtained the IP address.

IE is damaged, you can't open the web page but you can get on QQ, it's your IE that is damaged, and your friend's next super rabbit repairs IE.

Set up your network connection again.

Try swapping the two network cables.

A little dizzy, no network cable to go online, is your router a wireless route?

The school switch has implemented port MAC address restriction, which can check the number of MAC addresses connected on each port, and prohibit it if it is exceeded.

You can try to connect to the router and bind the MAC address to solve the problem.

Taking RL-R4149 as an example, the steps are as follows:

1. Enter the router management IP in the browser, default, press enter;

2. Enter the router administrator account and password, click OK, and the default is admin;

3. Click Network Parameters --MAC address clone;

4. Click to clone MAC address, and then click Save.

5. At the same time, set the WAN connection mode to dynamic IP mode, as shown in the following figure

Ordinary switches only play the role of signal amplification. The landlord's situation should be set up by your network administrator IP-MAC. Or it only restricts which MAC codes can be used to access the Internet. Computers that cannot access the Internet must be enabled by NMS.

I suspect it's a MAC bound to a network card.,In addition to setting up a router in the route, you can also get a router as a switch.,Clone the MAC of the route into a Mac that can access the Internet.,Theoretically, it's OK.,Try it if you have the conditions.。 There is also the use of that computer as an AP, the use of wireless router to bridge that computer, and then use other computers to connect to that wireless router can be, all theoretical, never encountered in practice. Can't test it.

This is a setting made on the network device, such as only allowing that person's MAC address, others are not allowed, and other people cannot access the Internet whether they are connected through a switch or directly. You're looking for someone to manage the setup network.

Bribe and bribe the teacher who manages the computer room, and bind a few MAC addresses to you.

The reason why the campus network connection is successful but the Internet cannot be accessed:

1. If there is a fault in the campus network itself (unable to access the Internet), it is recommended to contact the campus network maintenance staff to solve the problem due to non-user personal reasons.

2. There is a problem with the computer system, take the 360 disconnected first aid kit as an example

Open 360 Security Guard, click and select "All Tools", find the "Disconnected First Aid Kit" tool among all tools and run the software to check and solve network problems.

If it can't be solved, it will be disabled by the campus firewall, a firewall specially set up by the school to prevent students from surfing the Internet!

Not being able to connect to the Internet may not be a problem with the network cable, it is very likely that the problem is on the computer, whether your network number is locked and cannot be used.

1. Check it first, open the online neighbor, see if the local connection is grayed out, if it is grayed out, re-enabled, it can be used.

2. It may be that you have not logged in your account and password, and you can only use it when you log in.

3. Also check whether it is a problem with the network cable you bought, you can borrow a computer from your roommate in the same dormitory, connect this network cable, and try to see if it can be used.

1.To apply for a wireless data card, you can use the mobile phone data cable to connect to the computer to turn on the data and start surfing the Internet, but in this case, the risk is relatively large, and the mobile phone will follow once the computer is poisoned.

2.Go to the school to apply for a campus card, the school does not allow external broadband, but the campus card is sent by broadband, you can ask about this, the business hall in the school.

3.It is also a good choice to buy a wireless network card online for use, if your own economic conditions support.

The above are all personal opinions, personal testing is feasible, I hope it can help you.

You can apply for an unlimited data card.

The network is super unstable, or the network cable is in contact with the network, or the terminal is faulty
