How to set up two networks on one computer at the same time

I took it in the unit, connect the 3G wireless network card to the U port, you can use it, with software, the installation is also very simple, but others may access the Internet through you, because you can't disable your network card, otherwise the external and internal networks can not be on, you may also introduce the virus of the external network into your computer, and then spread to the entire local area network, and at the same time there is a danger of leaking secrets to the Internet, if your unit does not have this prevention requirement, you can use, I am in the power supply bureau, our electricity sales system is absolutely not connected to the external network, this can not afford to play, The dual network cards mentioned upstairs are not good, on the surface they are separated, but the virus will pass through your computer as a medium, although you have not built a bridge.

The ideal is to bring your notebook to the work and surf the Internet, and no one can control it.

It's better not to do this, because the organization has this requirement for confidentiality and intranet security, and don't do it, otherwise it will have serious consequences, very, very serious.

If you don't, you install two network cards on your computer, one network card address, and set the internal network cable for the internal network.

Connect an NIC to the Internet: Set the IP address of the Internet.

Also, you connect the internal and external network cables to the same switch, and then connect the cables from the switch to your PC, and add 2 IP addresses and gateways to your PC.

And finally, there are serious consequences for you to do this.

1. First of all, you need to connect the two computers to each other with a network cable. Then you need to modify the IP address to do so.

2. First of all, open "Open Network and Network Sharing Center" as shown below.

3. Click "Local Link" and then click Properties to enter. This is shown in the figure below.

<>5. After entering, we only need to set the "IP address" and "subnet mask". The other computer can also be set up by following the same steps above.

6. After setting, we open the command prompt to test, if it can pass, it means that the LAN has been set successfully.

First of all, you use the wireless connection first, and then disconnect, connect the network cable and then turn on the wireless, any of them will not be affected, if you want to use which is impossible at the same time, you can't use it for two purposes.

There is no way to use both. You can connect them all, but you can only use one type when you use them.

You need to use a VPN to use two networks at the same time, generally this situation is commercial, and it is only used when working on a special network, and the VPN has Shanghai Andat, which needs to be paid to buy, you should still be a student, and it is not practical to buy it. Even if you have the conditions to buy it, you still need to configure the permissions of this VPN.

Let me give you a popular example: for example, if I have installed China Unicom at home, and I want to go to the 11 platform to enter the telecom zone, I need a Xunyou accelerator to help me convert the network, so that I can play well in the telecom zone.

If you don't understand, you can ask.

If you're using a router, set the IP segment to the same IP segment, as you said upstairs, if you're not on the Internet, just make a network cable, 568a at one end, and 568b at the other end

You can buy a router and connect it, and if you have external network access, you can also use an external network line through the router to access the Internet.
