Do I need to set up a router to surf the Internet in a local area network?

To go to the external network, you must have an external network cable, and it seems that you only have an internal network there.

A router is simply a device that converts one network into multiple networks (or wireless signals).

If you have an external network cable, you must first figure out the Internet access method, if it is dial-up, you must set the router's Internet access mode to PPPOE automatic dialing and set a password. If the network cable is connected from an upper-layer router, then (in general) the route is set to automatically obtain the IP address. And set the routing LAN port address to be different from the upper-layer routing in the same network segment.

The premise is to have an extranet.

First, can I use the Internet before, if it is only for office use with a few internal computers? Now to purchase a router, you need to apply for broadband.

Then look at the type of broadband, there are two kinds of enterprises, one is enterprise broadband, static IP, and the other is the use of ordinary broadband, dial-up Internet access.

Second, you can also access the Internet before, but now you can add a router, in this case, the router can only be used as a switch.

Set the WAN port parameters to automatically obtain (dynamic IP address) and change the LAN port parameters (not the same as the company's LAN segment, otherwise the IP address will conflict and all networks will be disconnected). After the router is set up, connect a network cable from the switch on the company's intranet to connect to the WAN port of the router.

Generally, the more important departments of the enterprise are intranet, and that is not allowed to go to the extranet. Nor is it allowed.

If you want to get on, pull a network cable,

After linking according to the manual, if it is a direct connection route for the main line, you can put the password in the routing setup wizard, and the next step, the next step! The routing IP instruction manual should be available behind the route, as well as the password.

1. First, check the router's management address or IP address, username and password.

2. Plug in the network (LAN port) connected to each computer and turn on the power of the router.

3. Enter the router IP address or management address in the browser address bar, and then press Enter.

4. Enter the "Username" and "Password" on the pop-up login page, and then click the "OK" button.

5. Click "Network Parameters".

6. Click LAN port settings, then set the IP address you need on the pop-up "LAN port settings" page, and click the "Save" button after setting.

7. Click "HDCP Server".

8. Click "HDCP Service", and then enter the page to set whether to enable "HDCP Server", if so, you need to set the address pool. Once you've set it up, click on the "Save" button.

9. Right-click "Computer" on the desktop of the computer, click "Properties", and on the newly opened page, select "Change Settings".

10. On the "System Properties" page, click the "Change" button.

11. On the "Computer Name Change" page, change the team name to the name you need and click OK.

First of all, all your computers are set in a network segment, such as all set to. The subnet mask is. The gateway is set to a router for telecom public, and I am waiting in Guangdong.

The computer is set up in a workgroup, and the XP system needs to open a guest user. Also see if you have open files and printer sharing!

Once you have done the above points, there will be no problem with the software settings!

Your operating system is too complex.

There is no problem with the hardware connection.

It's just that the software is cumbersome.

First press the ** on the back of the router to set up the router, after setting up the router, just connect it directly to the computer, and the system is ready to install the same!
