What to do if you can’t save IP address settings in Windows 10

What to do if you can’t save IP address settings in Windows 10

In case you get an error when changing the IP, first check that the input does not have any typos. Proceed to the methods in the article if you are sure you have entered everything correctly.

Method 1: Replace the subnet mask with the prefix length

Normally, Windows automatically obtains an IP address, but sometimes when manually substituting the address, subnet mask, and other data in network connections, an error appears that the settings cannot be saved.

In the latest versions of the Windows 10 operating system, this IP problem is becoming more and more frequent. This is because the subnet mask values ​​specified above no longer work, since you must specify the length of the subnet prefix. Before the IP setting was written as 255.255.255.0, now you must use a length of 24. It can range from 1-64 for IPv4 and 1-128 for IPv6.

Since the problem occurs during an IP address change, it doesn’t make sense to describe the algorithm for going to system configuration with a parameter change. To fix the error, try changing the values ​​for subnet: from mask to prefix length.

The problem is how to know which prefix length corresponds to a given subnet mask value. The data including the 32-bit address used with the node address is found in the following table:

You can also calculate the length of the subnet prefix yourself. As we are used to, the mask is decimal and you have to convert it to binary and then calculate how many 1’s there are in a continuous sequence. For example, for a 255.0.0.0 mask, the 32-bit address is 11111111.00000000.00000000.00000000, which means there are 8 units, so the prefix length is 8.

Method 2: Configure the IP in the network connections panel

Try to change the IPv4 or IPv6 data in another way: through the network connections section in the classic “Control Panel”:

To go directly to the “Network Connections” window, to bring up the “Run” dialog at the same time you press the “Win ​​+ R” keys. In the special line, enter ncpa.cpl and press the “OK” button. or press the “Enter” button.

In the list that appears, locate the connection in use, right-click on its name and select “Properties” from the menu.

A list of components will appear in which you must select the protocol to edit, for example “IP Version (TCP/IPv4)”, highlight it and press the “Properties” button. below.

Check the items with manual editing and enter the necessary values ​​for the IP address and other settings. Save the settings.

Note that in this case you have to enter the subnet mask and not the prefix length as in the previous method.

Method 3: “Windows PowerShell”

You can also change the IP network settings through the Windows 10 console – “PowerShell”, – using special commands.

Run “Windows PowerShell” as administrator. Click on the “Start” icon. right-click and select the appropriate option from the context menu.

Enter the netsh interface ip show config command to open the list of network equipment with its parameters and press the «Enter» key. Pay attention to the line where there is information about the active adapter and remember its name.

Next, enter the following command with the parameters corresponding to the network configuration – netsh interface ip set address name= “имя сети” static IP-адрес маска подсети шлюз. In our case it will be like this: netsh interface ip set address name= “Ethernet” static 192.168.1.2 255.255.255.0 192.168.1.1. Press the Enter key to apply the settings.

This method may work if you change your network settings through the “Settings” app. fails due to error. In this way, the IP saving error can be resolved.

Method 4: Reset network settings

Resetting your network adapter and getting rid of unable to save IP settings error can help reset TCP/IP settings, which means resetting your computer’s network settings to zero. This can be done in a number of ways, including the “Settings” app. и «Command line». There is also an option to completely reinstall the network hardware driver. Our separate material describes the reset procedure in more detail.
