The server NIC is configured to be manual, and it will be automatically obtained after a while

It is estimated that the driver is not installed.

Your registry has been changed by someone else, so it is recommended that you clean up your computer.

1. After disabling the network card, then set and save it, and return it to automatically obtain it after the network card is enabled. Generally, it is a system file error, which can be judged by the command line pconfig all, and it is difficult to fix, and the system is generally redone.

2. The NIC ban is enabled normally, and it will be automatically obtained after the system is restarted. Generally, the NIC driver does not work properly, resulting in the system being judged to be new hardware and reinstalled every time. Generally, you can update the NIC driver.

3. Hardware compatibility failure. This kind of fault is a bit troublesome, and you need to solve the motherboard, network card, and system. compatibility issues. Generally, try to fix the network card PCI addressing, motherboard BIOS update, etc.

Generally, this kind of fault is caused by the second phenomenon, that is, reinstalling the NIC driver can be solved.

It's through the router, and you need to set it up in the router.

Of course, the automatic acquisition will change, and the fixed IP will not be set to the local area network of the factory, and the automatic acquisition will of course change the IP address according to the different situations at the time. If the network speed is slow, you can find the person in charge of the network in the factory.

This depends on how the DHCP server in your factory is configured, generally like you said, the IP changes every time you boot up, and it generally expires, so you have to reassign a new one to you!! You said that it will come back after manual settings and then automatically obtained, and it is estimated that the period of IP assignment in your factory is very short, and it will expire all of a sudden!! You can't do anything except be able to log in.,Let's analyze this situation.,You set up the same IP as the one you get automatically,In principle,The network speed is the same,Because the router will only limit the speed by IP.,It doesn't matter if you get it automatically or manually assigned.,As for what you said you can't do anything except be able to log in.,Then I guess this,You're just concerned about entering the IP address.、Subnet mask、Gateway.,Didn't fill in the DNS server address.,Because only the DNS server is filled in, The ** you enter on the webpage will be parsed into an IP address, and then you can access it!!

So you can try to fill in both the IP address and the DNS address!!

However, the following situation will occur when you enter it yourself, that is, the IP address is occupied, because this IP address is still within the allocated range, if someone gets this address before you boot the phone, and when you turn it on, you will be prompted that the IP is occupied!!

IP change is not a big problem, you can set a fixed IP, NDS address should also be set, otherwise you can only on, if you are a Guangdong user, you can see if these two NDS addresses can be used.

Generally, the last digit of the IP address is not certain and random every time the computer system automatically obtains the IP, but it generally does not affect the use, and there is no need to deliberately change it to the same every time, unless it has caused the Internet to be unable to access the Internet.

The "cat" is a dynamic IP, and the light is a fixed IP, if you use a cat + automatically obtain the IP, the cat will change one IP at a time!!

Auto-fetch means that the computer will automatically look for a DHCP server on the network and let the server assign itself a usable IP address.

A fixed IP address means that your IP address has been fixed.

Generally, LANs with centralized network egress are automatically acquired, which means that the IP address may or may not change. It changes because the server reassigns you one, and it doesn't change because the server assigns you the same one you used last time.

If you have access to a server, you can extend the validity of each rental in the DHCP service. This validity period is the interval between the last time you applied for it and the next application, and if it exceeds the server, it will give you a new one, and if it is not exceeded, you will continue to use the previous one. Server assignment IPs generally go up from small to large.

If you want to fix it, you can also get it automatically, and remember your computer's IP address and gateway, DNS or something after you can surf the Internet. Then change it to define the IP address and fill in the parameters just now. In this case, your computer is fixed and can be used normally.

But the only bad thing is that if you don't turn on the phone, this IP has been used by others, and if you turn it on again, it will squeeze others down. This is not something that the webmaster or anyone else is happy to see.

The best way is to reflect like the gateway and ask him to assign you a fixed IP.

IP change is not a big problem, you can set a fixed IP, NDS address should also be set, otherwise you can only go to QQ, if you are a Guangdong user, you can see if these two NDS addresses can be used.

The LAN in the factory, of course, will change the IP address according to the different situations at that time.

If the network speed is slow, you can find the person in charge of the network in the factory.

Of course, the automatic acquisition will change, but setting a fixed IP will not.

Set up your computer to automatically get DNS as follows:

1. Move the mouse cursor to the taskbar start icon and left-click the start icon.

2. Select "Control Panel" on the left side of the pop-up startup menu, left-click to select;

3. Select "Network and Sharing Center" in the control panel interface and left-click;

4. Select "Change Adapter Settings" on the left side of the Network and Sharing Center interface that opens.

5. Left-click in the network connection interface that opens, select "Local Connection", and then right-click.

6. Select "Properties" in the pop-up menu and click the left mouse button;

7. In the pop-up local connection properties window, find "Internet Protocol Version 4" and left-click to select it, and then left-click "Properties" in the lower right corner.

8. In the pop-up window, select "Automatically get the DNS server address", and then left-click the "OK" button in the lower right corner.

After completing the above settings, when you start the computer again, the computer will automatically get the DNS address, and you don't need to set it again.

1. There is no way to set a fixed IP for the broadband connection of virtual dial-up, which is provided by telecom or other network service providers!

2. The router is assigned the IP to you, enter its own route, point WAN configuration, and there is DHCP below, if the router turns on the DHCP service, then you can choose to automatically obtain the IP when setting up the computer. If you select Static Route for Route Settings, you need to manually specify the IP address on the computer.

Steps to fix an IP:

1. Align the small network icon at the bottom of the desktop to open the Network and Sharing Center.

2. Open the local connection.

3. Select the properties of the local connection status, find the Internet Protocol version 4 and click Properties.

4. Click to use the IP address below and start the setting, according to your own router settings.

Procedure to query an IP address:

1. Start-Run-Enter cmd-Confirm-Enter ipconfig-Confirm.

2. You can get to the default gateway value of the default gateway .x and y both represent values from 0 to 254.

3. Go back to the place you just set the IP address to .k is a value from 0 to 254, whatever you want. But k cannot be equal to yOtherwise, you won't be able to get online.

4. The subnet mask is set to .The default gateway setting is the same.

5. The preferred DNS is set to , and the standby DNS server is set to .

You disable the local connection and then enable it!

It's okay to be clear, or take a screenshot.

Generally, it is automatically obtained, unless it is provided by the access service provider and requires manual input. If you know it, it should be better to set it directly than to get it automatically.

Whether the DNS is automatically obtained depends on whether your IP address is automatically obtained. Normally, broadband is acquired automatically, and if it is a broadband dial-back, it is fixed. Of course, it is not absolute.

Automatically get convenient Manually access the Internet quickly when the computer is turned on.

Theoretically, it is good to set it manually, but in some cases it seems that it cannot be set.

Manual is good! Automatically, sometimes you can't get it, and you won't be able to open the web page!

There are pros and cons to automatic and manual, there is no good or bad, and their differences are as follows:

Automatic acquisition: Advantages: Automatically obtain the DNS server configuration parameters from the gateway, which does not require user intervention, no configuration, and is convenient.

Disadvantages: The gateway needs to inform the DNS configuration information, if the correct configuration parameter information is not returned, the connected client cannot access the network service through the domain name, and the DNS is determined by the gateway, which provides convenience for DNS hijacking.

Manual setting: Advantages: Users can customize the DNS server information, and you can choose a high-quality DNS server, which reduces the occurrence of DNS hijacking to a certain extent.

Disadvantages: It needs to be set by the user himself, needs to have a certain network foundation, is not suitable for beginner users, and improper setting will also cause abnormal network access.

Directly let it get it automatically When it is manual, it will first contact the router to cancel the original IP and request a new IP, which requires a response from the router, that is, the display is getting the network address, which is very slow You can restart the machine and the router.

Click the Start menu on your computer, and then click Control Panel.

Click (Network & Internet).

Click on "Network and Sharing Center".

Click on "Change adapter settings".

Tap on "Wireless Network" and then tap on "Properties".

Click on "Internet Protocol Version 4" and then click on Properties.

Light up the circle icon according to the image below, and then click OK to it.

There are two most common types of settings: choose between a subnet gateway and a subnet gateway for China Telecom.

It is recommended to manually set the IP address, is your network an internal network or an external network? If it is an external network, set a random one ( If it is an intranet, then look at the range of your LAN IP segment, generally The automatic acquisition of IP will directly affect the speed of boot and the delay of the network In addition, you say that the network connection but QQ and the web page suddenly cannot be connected? It is recommended to check the line well, if the line is normal, it is a virus in the computer, hehe, or received an ARP attack or DDOS attack and worms, antivirus install a firewall!
