One switch, two computers Internet access problem Rush Rush 20

ADSL: ADSL (Asymmetrical Digital Subscriber Loop) 2. Initial Router Settings: IP Address:

Username: admin Password: admin Step 1:

Enter the username and passwordUsername: admin Password: admin Step 5 of the Setup Wizard appears:

Select the export type, and the setup wizard appears: Set up the external network export adslStep 6: Enter the Internet account and password, and enter the Internet account account, which is similar to 86133833@vpn-cdjyxx initial password: 1234

3. Let the router dial automatically: Click on the network parameter option and select the WAN port setting to let the router dial automatically.

4. Check the router running status: Click the running status option to view the router status.

The normal router running status is as follows: 1. When using firewall and MAC address filtering, you should pay attention to the application of rules. 2. The router should be turned on and off normally, and directly plugging in the power supply will cause damage to the router and cause dial-up delay due to boot self-test.

If the belt has a function, set up the switch dial-up, the client (that is, your machine does not need to dial) connects the external connection line to the main port of the switch, and then the clients connect to the switch separately, and then set the IP, the gateway, according to your IP analysis, the gateway setting achievement can be (mainly the same as the gateway of the switch).

You have to divide your IP address and the router's IP in a segment, write the router's IP address in the gateway, and use the router's IP to enter the router management interface to set PPPOE, what account password and the like, the second machine tries to be the same!

1: Set up the router first to ensure that the router has been dialed up to the network normally. The default IP address of the router is basically 192 168 1 1

2 Set the IP of both computers to 192 168 1 xx and the gateway to 192 168 1 1

3.OK.

I only know how to set up the Internet with a router, but the switch, I'm sorry.!When I buy a router, I can!

You can't access the Internet, just use a static IP

address is sufficient. A static IP address is an IP segment that can directly access the Internet, and the IP will assign an IP address to you when the ISP is installed, so that the computer will no longer automatically obtain the network address when connecting to the network.

To avoid the trouble of network connection, broadband operators will provide IP addresses and subnet masks one by one.

Gateways and DNS servers.

address to the user. If you don't use a router, you only need to connect this home network cable to the computer and manually set the IP address on the computer so that the computer can access the Internet. The static IP address does not change and is mainly used for ** applications or services on the Internet.

Some gamers and people who use VoIP tend to choose static IP addresses as well because it's easier to communicate.

Dynamic IP addresses are relative to static IP addresses. First: in order to save LP resources, the machine that accesses the Internet through ** dialing, ADSL virtual dialing, etc., is not assigned a fixed IP address.

Target. Instead, it is dynamically and temporarily allocated by ISP to improve LP address utilization. Second, in the local area network, for the ease of client setup, dynamic IP address is often used, which means that the LP address you get is different every time you connect to the Internet.

Although this does not affect your access to the Internet, your friends, users will not be able to access you, and sometimes you will have the wrong password.

I hope I can help you with your doubts.

Gateway and DNS check it.

If the internal network can be pinged, it means that the IP is fine, but if the external network is not connected, the problem is concentrated on the gateway and DNS.

You can connect the router again, which means that you must connect the WAN port of the router when the switch comes out, the DHCP of the router is not turned off, and the computer that cannot access the Internet can get the IP from the router, including the gateway and DNS, so OK

Then the problem is in the switch.

Show sigh good,That is, you can't connect with the outside.,Just prompt with you.,Generally look at the IP to know it's different from others.。

The simpler the switch, the better it is, the more advanced it is, you can do those settings, or you can change the port and see, not just one port. You can check it out with the exchange port where you can access the Internet.

It is possible that the DHCP address of the router connected to this switch is automatically assigned and the computer cannot access the Internet, indicating that the address automatically obtained from the switch to the router is not available, resulting in the inability to access the Internet.

One of the computers connected to the same switch cannot access the Internet, and the reason why it cannot access the Internet is because it is not connected to the network.

1. Problems with network cables.

2. Problems with network cards.

3. The computer LP is not set to the right.

4. Problems with switch ports.

First of all, I am not a professional.

There is only one possibility in this case, and it is for some reason, which causes intranet IP conflicts.

You can try to change the position of this machine, or reset the network card.

First, check whether the IP configuration is correct and whether the DNS is normal, and test the ping gateway to see if it can pass. Second, you can tracert the Internet IP address to see that ** is not available.

The MAC address or IP address of this computer network card has been manipulated by the gateway.

Check the network cable and excuses.

If a computer fails to transfer to the same switch, it may be due to one of the following reasons:

1.Network cable failure: The transmission failure may be caused by a damaged network cable or loose connection.

2.Computer configuration problem: The computer may have a problem with the network card or other network configurations, which may cause the computer to be unable to connect to the network normally.

3.Switch failure: If only one computer cannot connect to the network, you can try to solve the problem by changing the port or restarting the switch. If multiple computers are leaking and can't connect properly, it's likely that the switch itself is faulty.

You can first check whether the network cable is connected stably and confirm that the network configuration of the computer is correct. If the problem persists, we recommend that you contact the network maintenance personnel for further troubleshooting.

Hello dear, the solution to the switch appearing 2 networks is:1Confirm the port connection of the switch:

Check the port connections of the switch to see if there are multiple ports connected to different network devices. If different network devices are connected to the same switch, it is easy to cause two networks to occur. 2.

Check the IP address of the network device: Check whether the IP address of the network device belongs to the same CIDR block. If different network devices use different IP addresses, the switch will have two networks.

3.Configure VLANs: Divide different network devices into different VLANs, so that different networks can be isolated through switches to prevent networks from interfering with each other.

Change the IP addresses of different network devices to the IP addresses of the same network segment, so that the switch can identify only one network. It should be noted that the above methods need to have a certain network knowledge and technical foundation, such as Kaifuguo If you are not sure how to deal with it, it is recommended to seek help from network technicians. At the same time, for enterprise-level network environments, it is recommended to use professional network equipment and technical solutions to ensure network stability and security.

Accessing the Internet via a computer-to-modem (either directly or indirectly through a switch) requires a virtual dial-up on the computer's local machine to connect to the Internet. Usually, an account can only be connected and logged in on one computer.

Based on your description, make the following judgments:

1. Your switch is equipped with routing function, and the user name and password of virtual dialing are originally configured in the switch, and the virtual dialing is automatically performed to log in to the Internet through this switch with routing function. The four computers connected to the switch are connected to the Internet on the external interconnection network of the switch in the LAN composed of switches.

The situation you mentioned happened because the configuration of the user name and password of the virtual dialing originally configured in the switch was lost or invalidated, resulting in the loss of the function of the switch's automatic virtual dialing to log in to the Internet. You need to log in to the internal settings page of the switch to set the virtual dialing function again.

2. Your switch is not configured or has a routing function, but the other three of your computers access the Internet through a virtual dial-up connection that shares one of them. The other three units cannot share the Internet due to an invalid configuration of the network share, regardless of whether the share is implemented through system settings or software settings.

3. Because your problem is still not described in detail and clearly, I personally think that the first judgment is more likely. In addition, even if your ISP account is multiusable, it can only be four computers through four cats using the same account to virtually dial in to the Internet. If you're using a cat, then I judge that it should be that your switch has a routing function, and it is more likely that four computers are connected to the Internet through a virtual dial-up that shares this switch with a routing function.

You can't use a layer 2 switch, you have to use routing, and the computer you can access the Internet is also dialed up, not local. Let's put it this way, the operator gives you only one address, if you want to 4 units to go online together, you must use a private network address, the device under the cat must have a routing function, and the dial-up function is converted to the public network by nat. Go buy a home router, a few dozen dollars, and just set it according to the manual.

Are you sure that you can use 4 computers before, what is the model of your switch? Did someone else give you a shared broadband before?

Or power off the switch, turn it on again, it's good if it's good, it's not good, it should be the switch is broken,

If there is a problem with the interface, see if it is loose, and pad it if necessary.

Is it blocked by the network operator? It's better to use routing. Automatic dialing is possible.
