It is a common problem that the laptop cannot access the Internet when setting a static IP, which may affect our work and life. In this article, we will explore the causes and solutions to this problem.

Let's understand what a static IP is. A static IP is a fixed IP address that does not change with changes in the network. In contrast, a dynamic IP is a dynamically assigned IP address that changes according to the needs of the network.

Normally, we can access the Internet normally using a dynamic IP. However, in some cases, we need to use a static IP, such as when we need to remotely connect to other devices or need to access controlled network resources.

However, when we set a static IP, we cannot access the Internet. At this time, we need to consider the following reasons:

1. IP address setting error: When we set a static IP, we may enter the wrong IP address, subnet mask, or default gateway information, resulting in the inability to access the Internet. Therefore, when setting a static IP, be sure to carefully check whether the information entered is correct.

2. DNS server setting error: The DNS server is a server that converts domain names into IP addresses. If we set the wrong DNS server address, it will result in the inability to access the Internet. Therefore, when setting a static IP, be sure to enter the correct DNS server address.

3. Network connection problem: If there is a problem with our network connection, such as the network cable is not plugged in properly, the router is faulty, etc., it will cause the inability to access the Internet. Therefore, before setting a static IP, make sure that the network connection is normal.

4. IP address conflict: When the static IP we set is the same as the IP address of other devices, it will cause an IP address conflict and make it impossible to access the Internet. Therefore, when setting a static IP, make sure that no other device uses the same IP address.

The solutions to these problems are as follows:

1. Check whether the information such as the IP address, subnet mask and default gateway is correct.

2. Check whether the DNS server address is correct.

3. Check whether the network connection is normal.

4. Check whether there is an IP address conflict. If so, modify the static IP address.

When we encounter the problem that the notebook cannot access the Internet after setting a static IP, we must patiently check the problem and solve it one by one. Only in this way can we use the network smoothly and efficiently complete various tasks in work and life.
