Wifi doesn't have a valid IP configuration

Anonymous

I recently bought a windows 8 laptop which used to access the internet fine for a few weeks but after a couple of updates it has stopped accessing the internet. Now i am getting NO NETWORK ACCESS with the yellow exclamation mark

When i tried troubleshooting, i got the response, "Wifi doesn't have a valid IP configuration". I have tried many of the suggestions that i have found on the forum like resetting TCP/IP stack with the netsh winsock reset catalogand netsh int ip reset reset.log hit but this has not changed anything. please help me i am getting desperate here.

Hi Punnen,

I understand that you are facing issues with wireless network.

We appreciate your effort to resolve the issue. I suggest you to perform the following troubleshooting steps also and check if it helps.

The issue could be caused if there is a miss match in the IP address configuration.

Method 1:

Release and renew IP address for your computer:

a. Press Windows key + X and select “command prompt (admin)”.

b. Type ipconfig /release and hit Enter.

c. Then type ipconfig /renew and hit Enter.

d. Type Exit and hit Enter.

Method 2:

Follow the steps to manually assign IP address:

a. Open Network Connections by pressing Windows + X keys on the keyboard and select Control Panel. In the search box, type adapter, and then, under Network and Sharing Center, click View network connections.

b. Right-click the connection that you want to change, and then click Properties. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

c. Click the Networking tab. Under This connection uses the following items, click either Internet Protocol Version 4 (TCP/IPv4) or **Internet Protocol Version 6 (TCP/IPv6),**and then click Properties.

d. To specify IPv4 IP address settings, do one of the following:

• To specify an IP address, click Use the following IP address, and then, in the IP address, Subnet mask, andDefault gateway boxes, type the IP address settings.

e. To specify IPv6 IP address settings, do one of the following:

• To specify an IP address, click Use the following IPv6 address, and then, in the IPv6 address, Subnet prefix length, and Default gateway boxes, type the IP address settings.

f. To specify DNS server address settings, do one of the following:

• To specify a DNS server address, click Use the following DNS server addresses, and then, in the Preferred DNS server and Alternate DNS server boxes, type the addresses of the primary and secondary DNS servers.

g. To change advanced DNS, WINS, and IP settings, click Advanced.

Method 3:

An automated troubleshooter is a tool that can find and automatically fix some problems with your computer. These troubleshooters aren't designed to fix every problem, but they're a useful tool to try because they can often save you time and effort.

Run the Network Troubleshooter from the link:

Wired and wireless network problems:

http://windows.microsoft.com/en-us/windows/network-connection-problem-help#network-problems=windows-8&v1h=win8tab1&v2h=win7tab1&v3h=winvistatab1&v4h=winxptab1

This should resolve the issue.

Use network reset to reinstall network devices

Using network reset should be the last step you try. Consider using it if the steps above don’t help to get you connected.

This can help solve connection problems you might have after upgrading from a previous version of Windows to Windows 10, as well as fix problems where you can connect to the Internet, but not to shared network drives. It removes any network adapters you have installed and the settings for them. After your PC restarts, any network adapters are reinstalled, and the settings for them are set to the defaults.

Note

To use network reset, your PC must be running Windows 10 Version 1607. To see what version of Windows 10 your device is currently running, select the Start button, then select Settings > System > About.
1. Select the Start button, then select Settings > Network & Internet > Status > Network reset.
2. On the Network reset screen, select Reset now > Yes to confirm.
Wait for your PC to restart and see if that fixes the problem.

Notes

After using network reset, you might need to reinstall and set up other networking software you might be using, such as VPN client software or virtual switches from Hyper‑V (if you're using that or other network virtualization software).

Network reset might set each one of your known network connections to a public network mode. In a public network mode, your PC is not discoverable to other PCs and devices on the network, which can help make your PC more secure. However, if your PC is part of a homegroup or used for file or printer sharing, you’ll need to make your PC discoverable again. To do this, go to Settings > Network & Internet > Wi-Fi. On the Wi-Fi screen, select Manage known networks > the network connection you want to change > Properties, and then turn on the switch under Make this PC discoverable.

_--------------------------------

I tried everything, i read everything from the first to last and nothing worked, i did the above and it states that it needs to restart my computer and once it does everyrhing i working fine now. Hope this helps others. Thanks

method 1 brill found this after trying other things so simple

thanks

Hi Paul,

Please confirm if Method 1 worked for you. If so, I am happy for you. Are you running Windows 10?

My laptop used to have wifi until Nov 30, still doesn't have wifi. Luckily, I can use my son's laptop for now.

Hope someone will give advice soon.
