I have two microcomputers that I want to access broadband, what should I do?

One route, two hubs, because the longest theoretical transmission distance of the network cable is 100 meters, so the router is placed in one of the computers, the computer is directly connected to the route, and then pulls a line from the route to another machine, but every 100 meters in the middle to add a hub (cheap, 4 ports of dozens of pieces can be done) or switch (more expensive, more than 100 or so), the route also has more than 100. 400 network cables can be added, but there is a problem: how to provide the power supply required by the hub in the middle?

Indoors or outdoors? It is not recommended to use a network cable so far, so it is better to use a coaxial cable, but it is more expensive.

Supplement: coaxial cable can reach up to 800 meters. (Considerable).

100M Ethernet has a transmission distance of 3 km over single-mode fiber. 1000M Ethernet 1000BASE-LX can support single-mode fiber with a diameter of 9um or 10um, with a working wavelength range of 1270-1355nm and a transmission distance of about 5km. (**Quite expensive).

300 meters distance is too long, the maximum length of the network cable should not exceed 200 meters, otherwise the signal attenuation is too large, then you can still use a switch between two computers, the average length is small. Switches and routers are fine, routers are actually more expensive, but there is no need to use them.

The distance is too far to be achieved with a network cable. (Unless you use the hub as an amplifier, but the cost is high, it is not cost-effective).

Wireless APs can be used, and many second-hand industrial-grade wireless APs can transmit hundreds of meters. (The cost is also high, and the radiation is also large).

If you just share broadband Internet access, it is recommended that you apply for a separate line.

Better line 2, 3 hundred meters.

The router can access the network, but the two machines cannot be interconnected.

The two functions of the switch are interconnected. Then you can connect to the big net through the cat.

The connection setting method of the router is as follows: the network cable out of the broadband cat is connected to the WAN port of the router, and each computer is connected to the LAN port of the router, and the IP address of the computer network card is set to be automatically obtained, and the address of the computer network card is entered in the address bar of the computer browser. Log in to the router through the IP address of the gateway, generally the username and password are admin, select the WAN port settings, set your broadband account and password to the PPPoE mode (if it is a fixed IP, you should choose the static IP mode), save and restart.

The first plan: buy a router, but it costs a lot, about 100 yuan, the advantage is that as long as the router is set up, the computer does not need to be set up, you can connect multiple computers to the Internet at the same time.

The second plan: buy a network cable tee, 2 yuan, and then find two network cables to connect the two computers with the home network cable. Disadvantages: You need to install software or set up your computer's IP.

The Internet tether can be used but is not very stable, and the computer that is used as a server must be turned on before another computer can access the Internet, which is not very convenient. It is recommended to install the HomeShare (Software Routing) software (free) on two computers, and set the HomeShare software on the two computers, for example: one computer is set to, the other computer is set to, the mask is set to, the gateway is set to, the following connection type is selected as pppoe, and the network number is set to the same, for example:

312312 and enter your username and password below. Select the advanced options and check "Connect at startup", "Seamless switching". In this way, two computers can access the Internet at the same time, or one can access the Internet.

I'm not a professional, but I know a little bit, let's start with the first question, if more than a dozen computers are connected to the network at the same time, you need a router + a porous switch, first connect the network cable to the router, and then connect the switch, the switch is connected to the computer.

2 The cat is a fool-like router that can be replaced or not, but if you want to connect multiple computer routers, you must have, and the problem is the same as above, there must be a router and a switch.

3 If you want to use optical fiber, then the router should use a good one, which is related to your network traffic acceptance speed and delivery speed, more than a dozen computers at the same time use a network cable, the Internet switch is also a good point, which is related to the traffic acceptance and transmission speed of your computers.

According to the third point you said (my case is ten computers, each computer has 10 3D online games. This condition, it is recommended that you use a good router.

I don't know if there's a limit to your funds, and if not, it's best to have your own server.

This can ensure your Internet speed, and it is more convenient for future maintenance.

If you still recommend using fiber optics for your network, then buying a fiber switch can be fun.

If you want to play online games with internet speed, you should buy a router.

You don't need to change the cat, there is a port on the cat to connect to the switch, the router is up to 8 ports, so you still use the switch, you want to increase the computer in the future, just buy a little more like 24 mouths, if you don't add 12 ports, it's enough**It's not expensive, we go out to do Internet cafes, and the units use switches.

To buy a router, first set the computer IP to automatically obtain, plug the modem's cable into the router, and then plug in the computer's network cable separately.

Open the web page for input.

Enter the account number.

admin password admin

For details, you can look at the router instructions, go in and enter your broadband account, remember to tune the DNS to the same as the local DNS.

Now the cats sent by Telecom have several network cable sockets, and you can plug them in. If you don't have one, then you have to buy a router or switch, connect it to the cat, and then plug two computers into the router, which is generally fine.
