Windows 7 Home Premium. Was connecting to the internet fine but then after a reboot, the PC can not connect to the network, it has no IP Address. It just stopped working.

original title: ipconfig results is blank

Windows 7 Home Premium (service pack 1). Was connecting to the internet fine but then after a reboot, the PC can not connect to the network, it has no IP Address. It just stopped working.

When I run the command ipconfig I see only the following one line:

Windows IP Configuration

When I check the Wireless Network Connection, it is enabled. I can plug into the Local Area connection and it is also enabled.

When I check the properties of either one, the line Internet Protocol Version (TCP/IPv4) only has the option to install. You can't check the properties of TCP/IPv4. I was wanting to verify that it is set for obtaining an IP Address automatically. I can do the same on IPv6 and it works fine from the perspective I can see the options. Although I don't seem to get an IP Address. All other wireless devices are working fine in the house, I have rebooted the router many times and this one PC is the only one to not get an IP Address.

How do I get IP to work, to get an IP Address so I can actually get back out to the internet.

Thanks,

Scott

Hi Scott,

· Have you made any changes on the computer prior to the issue?

Follow these methods.

Method 1: Follow the steps:

Step 1: Boot the computer in safe mode with networking and check if the issue persists.

Advanced startup options (including safe mode)

Step 2: If the issue does not persist in safe mode with networking, perform a Clean Boot to see if there is any software conflict as clean boot helps to eliminate software conflicts.

Note: After performing the troubleshooting steps in clean boot, follow Step 7 from the link to return the computer to Normal startup mode.

Method 2: Disable the security software temporarily.

Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you do have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you are connected to the Internet or a network during the time your antivirus software is disabled, your computer is vulnerable to attacks.

Method 3: Follow the steps from the article.
