1. First of all, make sure that the route does not restrict the Internet access for your computer.
2. Determine whether another computer also automatically obtains IP, if it is not automatically obtained, then the routing should be to turn off the DHCP service, you can't get the IP, then you need to refer to the other computer to specify the IP, the IP should not be the same, the subnet mask, and the DNS should be the same. For example, the other one is: Yours is set to.
3. If the other one is also automatically obtained, then check your network cable and network head, whether the network cable is up to standard, the so-called standard to see the ** line of about 1 meter yuan is the standard line, if the network cable is up to standard, re-do the crystal head. It should be noted here that if the network cable is done in the computer market, the so-called pass is measured by the general market line tester, which only means that the line is connected, and does not mean that the network cable can work normally. Especially in the case of substandard network cables.
If the network cable is not up to standard, re-do the crystal head or can not be solved, then please adjust the speed of your network card from 100m to 10m to solve, don't be afraid of slow networking, this speed is more than 10 times faster than the speed given to you by telecommunications.
4. If the above processing is not solved, then reinstall the system. All has been done, if it has not been resolved, then please believe that there is a God in the world. Because that's something that simply won't happen.

IP address set a bit fixed!
-
Several computers all use automatic IP addresses, try it.

The solution to the network keeps showing that the IP address is being obtained is to follow the following 4 steps.
1. Right-click the network icon and select "Network and Internet Interface". Stuffy.
2. After that, select the Change Adapter option.
3. Since my computer is currently using WiFi, right-click on WLAN, select Properties, and then click Share.
4. Then tick the first red box in the picture below; The second red box for network connections is marked with the "Microsoft Wi-Fi Direct Virtual Adapter" logo, which is only available if the hotspot is turned on on the computer.
This is the decimal form of the IP address, and the format of the IP address is divided into four segments, each segment is a byte, and one byte is an 8-bit binary. The maximum value is that the address is divided into two parts, one is the network address and the host address. The network address indicates which network of the Internet it belongs to.
The host address indicates which host in the network it belongs to, and the two are in a master-slave relationship. <>
Network address: It is used to isolate the host address, and the area code is to isolate the ** number of different cities, and the network address can be used to plan and manage the host address in different environments, different fields, and different geographical environments. For example >>>More
Network address. Broadcast address.
Subnet mask. A valid IP address. >>>More
Press that flash fullscreen mode, then copy the next **, open your space, and create a new FLSAH module. Paste ** in the address field (url). Set the width of those at the back, you know. >>>More
This is a classless address. The host address has a C (how do I put it, that is, 254 available. Remove the network address of 0 and the broadcast address of 255). >>>More
Hello dear! Glad to answer for you: Here's how:
You can know the types of addresses (variable-length masks) based on the subnet mask, and the CIDR block based on the IP address. For example, the mask is a Class C address and the mask is a 24-bit roll. The network Li Zao address is a mask, a class C variable long subnet segment, a mask of 28 bits, a network address of 0, a broadcast address of 15, calculated by yourself, I haven't used it for a long time, and I generally use a subnet mask calculator. >>>More
