One of the common situations for Windows 10, 8, and Windows 7 users is having problems with the Internet and the message that the network adapter (Wi-Fi or Ethernet) does not have valid IP settings when using the standard network troubleshooting and troubleshooting utility.
This guide describes step by step what to do in this situation in order to fix the error related to the lack of valid IP settings and return the normal operation of the Internet.
Note: Before following the steps below, try turning off your Wi-Fi or Ethernet internet connection and then turning it back on. To do this, press the Win + R keys on your keyboard, type ncpa.cpl and press Enter. Right-click on the problematic connection, select Disconnect. After it is disabled, enable it in the same way. For a wireless connection, also try turning your Wi-Fi router off and on again.
Reacquiring IP parameters
If a malfunctioning connection receives its IP address automatically, then the problem in question can be solved by simply updating the IP address received from the router or provider. In order to do this, do the following steps.
- Run command prompt as administrator and use the following commands in order.
- ipconfig /release
- ipconfig /renew
Close Command Prompt and check if the issue has been resolved.
Often this method does not help, but at the same time, it is the simplest and safest.
Reset TCP/IP protocol settings
The first thing to try when you get a message that your network adapter does not have valid IP settings is to reset your network settings, specifically IP (and WinSock) settings.
Attention: if you have a corporate network and the administrator is responsible for setting up Ethernet and the Internet, the following actions are undesirable (you can reset some specific parameters necessary for work).
If you have a different version of the OS (but it is also suitable for "dozens"), then follow these steps.
Also, to reset TCP / IP settings in Windows 8.1 and Windows 7, you can use the utility available for download on the official Microsoft website: https://support.microsoft.com/ru-ru/kb/299357
After restarting the computer, check to see if the internet is back up and if not, if the troubleshooting shows the same message as before.
Checking the IP settings of an Ethernet or Wi-Fi connection
Another option is to check the IP settings manually and change them if necessary. After making the changes indicated in the individual paragraphs below, check if the problem has been fixed.
If none of these are helpful, try the options in the next section.
Additional Reasons for a Network Adapter Not Having Valid IP Settings
In addition to the described actions, in situations with “valid IP parameters”, third-party programs may be the culprits, in particular:
- Bonjour - if you have installed some software from Apple (iTunes, iCloud, QuickTime), then most likely you have Bonjour in the list of installed programs. Removing this program may solve the described problem.
- If you have a third-party antivirus or firewall installed on your computer, try temporarily disabling them and see if the problem goes away. If so, try uninstalling and then reinstalling the antivirus.
- In the Windows Device Manager, try to remove your network adapter, then select "Action" - "Update hardware configuration" from the menu. The adapter will be reinstalled, sometimes it works.
That's all. I hope one of the methods worked for your situation.
An Ethernet network adapter with invalid IP settings is one of the common problems when connecting a computer, desktop or laptop, to the Internet and local network. This error occurs in the seventh, and in the eighth, and in the updated, tenth, version of Windows. And it is determined after running third-party network utilities or a diagnostic tool preinstalled in the system. The main reason for this failure is incorrect network adapter settings. But there are a number of other points as well. So, let's dwell on them in more detail.
Windows network settings
Each NIC is assigned its own IP address. And the first thing we'll do is check it out. Open the "Network and Access Center" by clicking on the "monitor" icon. Select "Change adapter settings" to go to "Local Area Connection". Click on the icon and open "Status" and then "Details".
In the new window that opens, there is all the data about your network connection. We need "IPv4 protocol". The value must be written in it and there must be no address of such a plan: 169.252.X.X. If the field is empty or such addresses are registered, you will not be able to connect to the Internet. Also cannot be empty if you are connecting to the WAN through a router, the fields for "Default Gateway" and "DNS Server". They must contain values.
Empty fields indicate a failure of the DHCP server. Let's try to fix everything manually. Click on the "Network Connections" icon and select "Properties". On this tab, we need "Internet Protocol Version 4 (TCP/IPv4)". It is in this field that we will set the value of the IP address:
What do we write? If you are using a router, look at the bottom panel for its IP address. The value for the netmask will be 255.255.255.0. This is the case if you are connecting via a router. If the cable is connected directly, call your service provider - only he can fix the error with invalid network adapter parameters.
Routing, DNS cache and WInsock
So, first we will delete the routes of the network information, that is, we will clean the table.In Start, select Command Prompt and launch the console as Administrator by clicking on the appropriate menu item. We write the following commands in the text interface one by one and press Enter to execute:
The routing table is cleared like this:
route -f
The cache of the DNS Client service is cleared like this:
ipconfig /flushdns
TCP/IP protocol settings are reset as follows:
netsh int ip reset
netsh int ipv4 reset
netsh int tcp reset
Windows Sockets settings reset like this:
netsh winsock reset
Close the command console, press restart laptop / computer and check the status of the Internet connection.
Network adapter driver
The new edition of Windows brought with it a whole bunch of problems with connecting both over Ethernet and over the air. And the root cause of these problems is incompatible or unstable drivers for network cards. If the utility diagnosed the error "invalid IP parameters in the network adapter", the first thing you should do is make sure that the driver is available. However, if you updated the software, the driver was not installed manually, but by the system itself. But it doesn't work, so delete this one and install a new one.Where to looking for? Only on the manufacturer's website and only by adapter or laptop model. Type in the search and download the installation file or archive to your computer. Run the .EXE file and wait for the driver to finish installing. If the manufacturer has not yet released a driver for the "tens", download it for Windows 8.
PC security system - antivirus, firewall
If you installed a different antivirus program or set up a new firewall, this may be the cause of the Internet connection error. You can also use free antivirus software that conflicts with your network card, or a firewall that zealously protects your computer from network threats. In any case, disable antiviruses, firewalls, including the pre-installed firewall. It is desirable to suspend the work of the latter in the first place. To do this, press the Win + R key set and in the window that opens in the left corner write firewall.cpl. Another window will open with two links. Select the appropriate link to disable:
Disable private and public network. Close the window and start the Internet.
Clean Boot Windows
And finally, let's try the option of clean booting the OS to eliminate conflicts between the network card and third-party programs, applications, and services. Type Win + R and in the window that opens, copy the command: msconfigIf you click OK, a window with "System Configuration" will open. Open the "General" tab and select the "Selective startup" item on it, marking it with a checkbox, as in the picture:
Just below there is another item marked with a flag. To perform a clean boot of MS software, we need to uncheck "load startup items". Then go to the "Services" tab:
If you don't want only Microsoft services to be displayed, select the appropriate checkbox and click Disable All. Save the new settings and be sure to restart the laptop / computer. Check your Internet connection. Most likely, the problem with the IP settings for the network card should be resolved. Well, if nothing helped, you need to connect the adapter to another device. It is possible that the matter is in the laptop, and not in the network card.
Oddly enough, but many users of Windows operating systems, starting with the seventh version and higher, very often encounter a problem connecting to a local network or the Internet, and at the same time the diagnostic utility gives a description in the results that “the Ethernet module does not have valid IP settings ". The situation is not catastrophic, and the problem can be eliminated by several methods, which are proposed for consideration below.
Adapter does not have valid IP settings - what is the problem?
This situation can occur either when the current connection is configured incorrectly (it doesn’t matter if Wi-Fi access or a wired Ethernet connection is used) or if there are problems on the part of the provider.
In both cases, it will report that the connection does not have valid IPs.
To check in the network connections section, from the RMB menu on the selected network, select and then click on the details button in a new window. Next, you should see if the fields for the IP address, gateway and DHCP and DNS servers are filled.
If the IP address contains a combination other than 192.168 and beyond (for example, 169.254, etc.), such a connection will not work, and the problem is that the protocol is configured incorrectly on the terminal itself. If there are no values for the specified servers, it can be assumed that the problems occurred on the provider's side (the DHCP server crashed).
The network does not have valid IP settings: what should I do first?
The connection issue may be temporary. Therefore, when it is reported that the Internet does not have valid IP settings, you can simply disconnect from the network first and then reconnect.
This is done by clicking on the connection icon in the system tray or by calling the corresponding section with the ncpa.cpl command, where the disconnect line is selected from the context menu, and then reconnecting.
In the case of using a Wi-Fi network, as an additional measure, you can use a full reboot of the router by disconnecting it from the power supply for about 10 seconds, turning it on again and waiting for it to fully boot.
Reacquiring IP settings
However, the problem may also be in incorrectly set network settings. When the system reports that the adapter (or network) does not have valid IP settings, this is the most common situation.
To resolve the failure, you can use the tactic of reacquiring IP parameters. To do this, you will have to run the command console with administrator rights, and then write two commands in it, as shown in the figure below.
Then you should close the console and check the connection either by trying to connect or by using the same diagnostic tool. The message that the network module does not have valid IP settings may no longer appear.
Setting parameters manually
But this may not help, in particular when automatic IP acquisition is set in the current protocol settings. The problem description may again refer to the adapter not having valid IPs.
The way out of this situation is to set the correct values in manual mode. To perform these operations, enter the network connections section and, using the property line, go to the protocol settings (usually IPv4). Here you will have to enter the IP address yourself (the address of the router in which the last number has been changed), the gateway (the value must match the address of the router in the case of a wireless network), and for the DNS servers, set the values \u200b\u200bof four eights or two eights and two fours.
Reset network settings
In some cases, the previous operation may not be necessary. When a network connection does not have valid IP settings, a factory reset can sometimes be used.
In this case, you will again need to call the command line and take the following actions by entering the appropriate commands, as shown in the images.
After executing all the commands, you can check the network status again. Sometimes a failure can be fixed without problems in this way.
Clean boot system
Often, in correcting the situation with the appearance of a notification that the network module does not have valid IP settings, the so-called clean start of the system, that is, loading with the maximum shutdown of unnecessary services, can help.
To perform such a download, you will need to enter (the msconfig command in the Run console), on the general settings tab, set the selective startup line to active and uncheck the autostart item download line.
Next, in the same section, go to the services tab, check the box for hiding Microsoft services, located at the bottom left, and for everything that remains, use the deactivation button ("Disable all") at the bottom right. As a rule, when the system is restarted (which, by the way, must be performed without fail), the problem disappears.
Antivirus, firewall, third-party programs and drivers
However, the difficulties may not end there. The fact is that some antiviruses, the built-in Windows firewall and installed applications can also create connection problems.
In this case, you should first temporarily disable anti-virus protection. In addition, using the firewall.cpl command, you can open the firewall settings and activate the lines to disable firewall protection, although this is not recommended.
Finally, you should check the list of installed programs. For example, if a user installed iTunes, the Bonjour utility is installed with him, which can also cause a lot of problems. Perhaps its complete removal and fix the failure.
In the very last case, when nothing helps, you can try to completely remove the network adapter driver and install it again, after downloading the latest version from the manufacturer's website. To uninstall, use the "Device Manager", and the driver can be downloaded, for example, from another computer, and then transferred to your terminal by copying it to removable media.
If even this does not give a result, you can use the NetShell utility from Microsoft, which can be downloaded from the official website of the company.
Conclusion
In conclusion, it remains to add that at least one of the proposed methods can still fix the problem. It all depends on what exactly was the root cause of the failure. But in most cases, updating the IP parameters or setting the correct values \u200b\u200bin the protocol settings manually helps.
Of course, inappropriate hardware or incorrectly installed drivers, some unnecessary applications, antiviruses (most often free Avast) and the built-in Windows security system can also have a negative impact on the state of connections, but if everything worked before and then stopped, apparently, the problem is not in that.
The reasons did not indicate the impact of viruses, which can also lead to such failures. This is due only to the fact that each user, so to speak, by default, must monitor his system himself and undertake a check for threats, since even the most powerful protection tools are able to skip malicious codes or program modules that have just appeared, and in the databases no antivirus yet.
Network adapter
does not have valid IP settings
How to solve this problem
Quite often there is a problem in the local network for computers (Windows 7, Windows 8) - "The network adapter does not have valid IP settings."
This message appears as a result of Windows Network Diagnostics.
Of course, in this case, there is no access to local network resources or access to the Internet. As a rule, this happens due to incorrect settings of the network card of the computer or laptop.
But there are some other reasons that can cause such a malfunction.
More about this...
Windows network settings
The most important thing to start with is to check which IP address is assigned to the network card. To do this, you need to go to Windows network connections, right-click on the icon and select the "Status" button.
In the window that opens, click the "Details" button.
After that, another window appears with all the available information about the network connection.
We are interested in the field "IP addressv4. It must not be empty - it must have a value. Moreover, if the address there looks like 169.254.X.X, then the network will not work either.
If they are absent, then very often this indicates that for some reason the DHCP server has fallen off.
To fix the situation, you need to specify the addresses manually.
To do this, on the network connection, right-click again, select "Properties" - "Internet Protocol version 4 (TCP / IPv4)" and enter the IP addresses:
The network adapter does not have valid IP settings - the solution to the problem 27 comments The network adapter does not have valid IP settings windows 10 valid IP settings". This message is displayed in the results of the Windows Network Diagnostics Tool. I think it is clear that in this case there is no access to local resources or access to the Internet. Basically, this happens due to incorrect settings of the network card of the computer or laptop. But there are a number of other reasons that can cause such a malfunction. We will talk about them now. 1. Windows network settings The first thing to start with is to check which IP address is assigned to the network card. To do this, go to Windows network connections, right-click on the icon and select the "Status" menu item.

Also pay attention to the fields "Default gateway" and "DNS server" - if you are connected through a router, then they should also have values. If they are absent, then very often this indicates that for some reason the DHCP server has fallen off. Entering addresses manually can help.
