First Aid: Computer LAN Problems Habaug .

Connect the router to the port first, then connect the rest of the machines to the router, arbitrarily use one machine as the host, log in the network card, and then assign IP to all the machines, the specific operation is, select the local connection - > properties - > internert protocol. In fact, the router is a small gateway, and its IP is the default (, the host is set.

The rest of the machines are randomly set from to, and the next time it starts, which machine starts first, is the host. Haha, it's all done, it's a lot of fun!

Supplement: If you want to increase the number of computers in the future, you can buy a hub or switch to connect to the router to increase the number of ports.

Using a router may have some impact on the speed of the network, but in theory it is not very significant, and if there are special circumstances, you will have to consider other options. Good luck!

Let's talk about how to get on the net.

If it is broadband Internet access, turn on the cat's router, the cat is connected to the hub, and then connect to two computers from the hub, the two computers are set with a fixed IP, and the gateway is the address of the router, so that the cat is open, and both computers can access the Internet.

Connect the land-based rover to the cat and the computer to the land-based gamer. Then log in to the land gamer (method: enter in the address bar of the online neighbor: the default username and password are admin, and then use the system to guide the settings.

What you said about Habo, is a hub, that is, often said hub, in the dormitory directly with the hub router to form a LAN, from the total to the relationship is a router, hub, computer, routing generally default with IP address automatic assignment function, the hub 1 port connected to a network cable connected to the port of the router, and then connected to the hub of the computer and directly connected to the route of the computer best to use the manual configuration of the IP address. Set the CIDR block to avoid IP conflicts.

If you just build a LAN with hub, switch, or router, all of your IPs are set to a network segment, and the gateway is set to one.

The network speed of the route is fast, the network speed of the hub will be reduced, and there is no difference between other establishment methods!

Prepare a switch, connect all the network cables to the switch, and then manually configure the IP addresses of 3 computers.

It seems that I have encountered the same situation as you, in the same LAN, two XPs. A win7,The solution I use is to use Haofang battle platform,Although it's a little troublesome,But it can be used。

Win7 can be connected to the router LAN wirelessly to connect to the game (turn off the firewall).

The 2 XP connections will enter the LAN.

Once you're connected, change the team name to the same one for all four computers, which is workgroup, and then set the guest account password, and then you can share it with each other! Right-click on my computer to change the name of the workgroup! You can change the guest account password in Account Management.

Connect all computers to the route, and set the telecom username and password in the route (the address of the route is usually or. Then set the IP and gateway of each computer according to the IP of the route, so that not only can you connect to the Internet, but you can also share files.

Send me a detailed thing to my mailbox and I'll do it for you!

In fact, it is very simple, you don't need a router and a switch, you only need a crystal head (that is, a network cable), and the two computers are equipped with an IP on the network configuration, so that the first three addresses are the same.

Use a bounce back network cable and you're good to go.

A router or a switch will do.

The easiest thing is to get a crossover network cable to connect, if you want to be more complicated, it is convenient to expand in the future, you can buy a small switch to connect.

Install two network cards on a computer with a lot of memory.

The computer used to access the Internet adopts the unlimited Internet method, buy a router with unlimited functions and an unlimited Internet card (there are desktop dedicated ones), a total of about 200 yuan.

You can directly make a direct connection line, the connection network cable between the computer and the computer, and the computer and the switch are different, the line sequence is different, pay attention to this point, you can see the local connection after the connection, you can freely set the IP address to find the other party's computer, or right-click in the online neighborhood, select search for the computer, enter a or b computer name to find the other party's computer, and then set the directory that needs to be shared, copy the file.

Use a router or switch,Use a network cable to connect the two computers to the LAN interface,Open the LAN sharing of the two computers,There are batch files in the installation personnel tool in the general ghost version of the system,Just run it directly,Of course, your two computers are required to be in the same workgroup,This can be found and changed in the "computer name" column in the properties of my computer,So that you can copy the files in the two computers to each other。

This requires a special network cable, and ordinary network cables are not possible.
