If there is a computer under the same switch, it cannot access the Internet

First of all, check which floors can not be on, if the same switch is separated and cannot access the Internet, it is a problem at the lower end of the switch, if it is different IPs of different switches can not access the Internet, it may be a problem with the router. A power outage may cause the port to malfunction. Check the IP address of the computer that cannot access the Internet, whether the correct IP address is obtained, and then ping the gateway of the router to see whether it can be pinged.

If the switch is simple and cannot be configured, then everything can only be with the router. Since it is a bound IP and MAC, maybe the configuration was not saved in the early configuration, resulting in a power outage, and the configuration was lost. Maybe it needs to be reconfigured a little more.

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.

Are you still overwhelmed by the solution to not knowing that the computer connected to the switch can't access the Internet? The following is a solution that I have collected for you to not be able to access the Internet on the computer connected to the switch, welcome to read:

Topology] Internet --- routers--- switches, --- PCs

Phenomenon] PC cannot access the Internet.

1) Check to ensure that the network topology is connected correctly and the device indicators are normal.

2) Check whether the computer network parameters are correct, and make sure that the computer is directly connected to the router and can access the Internet: this can eliminate the restriction of the router on the computer's Internet access.

3) Try to log in to the router management interface and check whether the management address of the switch conflicts with the router gateway.

4) Check whether the browser is set up with LAN**, try to ping the gateway and the external domain name, if not, continue to check.

If these are all right, then you can locate the problem at the PC and the switch, which can be located from the following steps:

5) Check whether the PC connection port on the switch can communicate with the router connection port, and exclude the switch setting port learning, port and MAC address binding, VLAN (whether the port is in the same VLAN as the router cascade port), ACL settings and other restrictions.

6) Check whether there is ARP spoofing in the intranet, and do a good job of two-way binding between the IP and MAC of the computer and router.

7) If none of the above is set, the device reset is used as a fool switch, if you can't access the Internet, it is likely that there is a problem with the switch hardware, contact the office or dealer for detection.

I also want to see the "solution to the problem that the computer connected to the switch can't access the Internet".

1.The solution to the problem that the computer is directly plugged into the network and the Internet does not respond.

2.How to solve the problem that the desktop computer cannot connect to the broadband network.

3.How to solve the problem that the LAN cannot access the Internet normally.

4.What should I do if I can't connect to the Internet after connecting my computer to my router?

Due to the packet blocking of the LAN port of the router, it is often because the router is used for too long and heats up, resulting in the packet blocking of the LAN port and the error of sending data, so some can access the Internet and some cannot access the Internet.

Why can one of the two computers connected to the switch be able to go to the king and the other can not access the Internet?

1. Change to another network cable to see if you can access the Internet.

2. Use someone else's computer to test your network cable to see if you can access the Internet.

3. Eliminate the above problems and estimate the setting problems of your computer.

a. Network card rate mismatch: Take a look at the attributes of the computer's network card.

b. Whether the computer is turned on**.

c. Determine whether the network connection display is normal, and whether the packet reception and sending is normal. Use antivirus software to see if there are any cyber attacks.

d. Eliminate network conflicts, such as IP, MAC, etc.

Summary. First of all, check whether the local IP, gateway, and DNS are configured correctly, and you can first verify whether the gateway can be pinged, whether it is reachable to other hosts in the same network segment, or tracert, look at the path, and check that the path is not passable;

2.At the same time, understand the network planning, if there are files to check it, and have a good idea of the configuration strategy;

3.Log in to the device to view the configuration, including the configuration policies of the network egress firewall, router and other devices, and directly troubleshoot on the device to find the problem faster.

4.Some companies will connect personal routers privately, which may cause some problems to the network;

5.Troubleshooting, you need to understand network planning, understand the network environment, including network links, gatewayable switches, may have settings for each port, and network cables cannot be connected casually.

The computer connection switch cannot connect to other computers.

1. Policy problem 2, IP conflict 3, cable damage 4, hardware damage 5, DNS and so on setting problem 6, being spoofed 7, address pool and other settings 8, firewall and other settings 9, character problems ......
