The easiest way to tell me the setup of 2 computer interconnection 1 dual network card 5

If there is no router.

The easiest way.

If you put one of the machines, you have to add an additional network card, and you have to use it with three network cards.

On PC 1 and PC 2, click Start Run and enter netsetup inside Once the installation is complete.

**Cable connection ADSL cat -- connect to computer 1's A network card--- B network card connection--- connect to computer 2C network card.

Here's the setup.

Set the A network card of computer 1 to the external B network card is the IP of the internal network A network card

DNS is not filled.

b NIC is. DNS is not filled.

C network card is. DNS filled.

Set adsl dial-up on computer 1 to access the Internet, 2 machines are fine, as long as computer 1 is not turned off, you can go online.

A reverse network cable connects two computers, and the last three digits of the IP are different, and the previous one can be found in the online neighborhood.

I once tried dual network cards, there is a hardware conflict, I don't know if your machine will have a hardware conflict.

It is recommended to use a router, 75 yuan, and it is very convenient to operate according to the manual.

A card is an Internet network card, and B is a LAN network card.

For the gateway, the DNS is configured according to the ISP provision.

2.Set the IP address of the B card to the intra-LAN CIDR block, for example, the LAN CIDR block is, the mask is set to , and the gateway and DNS are empty.

3.Set two network cards to 100M full-duplex at the same time, you can access the Internet and LAN at the same time4Disable a network card,Then enable,Now you can go to the internal and external network at the same time and the above is effective in my personal test,You need to repeat the 4th step after each restart,Declare that I am also more dish,This is my own situation,Groped for a few days before finally solving,Although each restart to repeat the 4th step,But this has saved a lot of things。

You can't use it at the same time, and the two NICs can only be one master at a time, and not both of them, otherwise they will conflict.

You can set the IP segment of the network you want to connect to separately...

Just set them separately Is IE used for online tax filing? Then IE should be set to select the correct connection. Kingdee Finance also needs to set up a separate network.

I've tried this before, but it doesn't seem to be possible to use dual network cards at the same time.

Maybe you need to set up 2 connections, right?

Dual network cards are one computer (usually a desktop) with two network cards, and then another machine (usually a laptop) shares Internet access through this computer.

Benefits of using dual network cards to configure Internet access:

1.Economical - only need more than 30 yuan to buy a network card and a network cable to get it;

2.Stable - much more stable than using ** software, and the speed is also very fast;

Specific configuration of dual NICs:

One. Spent 25 yuan to buy a network card, and made one of the computers into a dual network card (you can add it yourself, you can go to the store where you bought the computer and ask him to add it).

Two. Spent 5 yuan to make a crossed twisted pair (there are in the computer market or a nearby network engineering store, and when he did it, he understood that the length was done according to the need. ）

Three. Set the property of the local connection 2 of the computer with the dual network card to manually obtain the IP address, four. Then set the property of the broadband connection of the dual NIC computer to share to enable the sharing of the Internet connection for this connection. And it is an automatic acquisition of IP addresses.

Five. Set the local connection of a single-NIC computer to automatically obtain an IP address.

Six. Connect a single NIC to a second NIC computer with a twisted pair cable.

In this way, as long as the computer with dual network cards can access the Internet, the computer with a single network card can also access the Internet.

The cross-twisted pair cable bought above can be used to transfer files between any two machines.

Just set the local connection of one computer to:

The other is set to:

And by setting up the working groups to be the same, you can find each other in your online neighbors.

Frequently Asked Questions about Dual NIC Configurations:

The two computers can't communicate properly, and the online neighbors can't find each other.

Solution: My Computer Right-click Manage Options Local Users and Groups Users Put all the options in the properties of the items in the right bar on behalf of the red cross, except for the checkmark before the password never expires.

NIC 1: NIC 2:

The subnet masks are:

Gateway: That's it, it's OK!

Who to communicate with, if you want to think of the incoming network as the outgoing network, just set up a bridge.
