The router assigns an IP, and the router is set to automatically assign an IP, but it still can t ac

1. All devices connected to an interface of the router must be in the same network segment as the IP address of the router.

But it doesn't mean that the IP of the router is, you can't set it for the computer, you also need to look at the setting of the subnet mask.

2. You need a multi-port switch or hub.

3. You are wrong......A broadband router is not the same as a router in the traditional sense.

The main function of the router is to send requests from the LAN to the external network to achieve connectivity between different LANs and between LANs and WANs.

The main function of the switch is to form a local area network, and the switch has many interfaces and fast speed.

In addition, you have not figured out the problem of the server, the server is to provide a variety of services, the router can share a part of the role of the server, such as DHCP and DNS, but it cannot completely replace the server, such as the essential web server and FTP server must be undertaken by specialized computer equipment.

1.Different network segments must not be able to access the network. Unless the route is set.

2.If you don't have an autodial for anything in it, you'll have to get another one.

3.Your perception is right from the ground in terms of use.

You're right!

It is mostly a combination of a router and a switch.

Don't think too much about it, go buy it, just bargain more.

The router settings have changed, and the Internet cannot be accessed.

Solution: Set up the DHCP service of the router and assign a static address: Log in to the road and enter it in the browser""Log in, with the branch name and password by default is generally admin (different brands of router addresses are different, if you don't know, you can check the annotation on the surface of the wireless router), <

Once you're in the wireless router, select it"DHCP server"of"Static address allocation"For that item, fill in the MAC address of the mobile phone WiFi (a total of 12 digits, such as: 43:9U:

d3:ff:21:

du or 43-9u-d3-ff-21-du, different brands have different formats), fill in the IP address you want to divide the address (such as: , where 199 can be changed to any number from 1 to 255), the status selection takes effect, save the settings, and the mobile phone can go online immediately.

1.Restart the router and modem: Sometimes, there may be a problem with the connection between the router and the modem, resulting in a loss of internet access. Try restarting the router and modem separately and wait a while before reconnecting.

2.Check Physical Connections: Make sure that all physical connections are in order. Check that the cable between the router and the modem is plugged in tightly, and that the cable is not damaged.

3.Reset the router: If none of the above methods work, you can try to restore the router to factory settings. Use the reset button on your router (which usually requires pressing the button with a slender object) to restore the router to its default settings.

5.Check DNS settings: In the router settings, check the DNS settings. Try setting the DNS server to get automatically, or manually specify a reliable DNS server address (e.g., Google's DNS server is and.

6.Contact your network service provider: If none of the above methods work, we recommend contacting your network service provider to report the problem. They may be able to provide a more specific solution, or troubleshoot remotely.

Telecom allocates a public IP address.

You yourself are assigned a LAN IP address.

To use an analogy, the public IP address is equal to the street name, and the LAN IP address is equal to the name of each room number in the community.

Under the LAN, you only need to use the LAN IP address to access any computer, even if you unplug the broadband, you don't need the public IP of Telecom. It doesn't prevent you from visiting each other on the computer in the LAN, but you can't go to the web page, QQ, etc.

It's just a data channel from the telecom room to your LAN router, which reaches the door of your community through this street.

If you have a fixed IP, if it is a general household ADSL broadband, it is a dynamic public IP, that is to say, after each routing dial-up, the telecom will randomly assign the public IP, and the public IP address obtained from the first dial-up is different.

In the same way, if these four IP addresses are automatically assigned by the DHCP router. The computer is set up to get it automatically. Then the four computers are randomly assigned IPs, and they may be different every time they are turned on.

If the computer network card is changed to manually set the IP address, mask, gateway and DNS

A machine is B machine is...

Then the same IP address will be used every time you boot up... This has nothing to do with the DHCP route, and it doesn't do anything if it is turned on or not).

The 192 IP is a private IP that everyone can use at will, and cannot be routed on the public network. 183 This is a public IP address that can be routed. Therefore, when users go to the Internet, they need to convert the private IP to the public IP before they can be routed on the public network.

In your case, PAT is generally used, which is port translation. When each private IP enters the public network, an additional port number is added when performing IP conversion to distinguish different private IPs, because you have only one public IP address. The external data is sent to a computer in your LAN, and it will query which private IP corresponds to according to the previous conversion record, and then the data will be passed again.

The external network is assigned a static address to you, and all intranet users are connected to the Internet by the router. is the address that your router assigns to each computer on your intranet.

The IP assigned to me by telecommunications is your public IP address, the latter is the address of each computer in your local area network, and the computers in the LAN can access each other as long as they are used, if the external network computer wants to access the computer in your LAN through the Internet, you need to access any of your computers through this public IP address, at this time, it is through the router to analyze the data packets, and then find the corresponding computer through the routing table.

The network IP address is the public IP address, and the router assigned IP address is the private IP address. In layman's terms, explain the relationship and difference between the two:

A public IP address is an IP provided by an operator and is a "house number" on the Internet. For example, if you have a router at home, you must have an intranet IP, which is a "house number" of the intranet. The "house number" is "unique" so that others can "find" it.

Of course, there is no route and there is also a private IP, because a fixed IP is set in your local link.

All right. I think you have three questions.

1. It is a public network address, which is used to realize all your computers to access the Internet. After you set up the network, you don't care about it.

2. is your LAN address. These addresses enable your LAN to access each other and share your network.

3. If you want to access each other, naturally enter the LAN address.
