Try resetting the TCP/IP stack

open a command prompt, click Start and then type cmd in the Search programs and files box.
Under Programs, right-click the CMD.exe icon, and then click Run as administrator.
When the User Account Control box appears, click Yes.
At the command prompt, enter the following command, and then press Enter:
netsh int ip reset c:\resetlog.txt

Note If you don't want to specify a directory path for the log file, run the following command instead:
netsh int ip reset resetlog.txt

Restart the computer.

Hi,

I have few questions for you that will help me understand and narrow down the troubleshooting route.

Any Antivirus/Firewall Application installed? Yes/No
What type of nework type are we using - Wired/Wireless?
Are we using a in-built network adapter or custom installed?

Did you try the same network adapter in the other Windows 7 machine? (Non-Home Premium Edition)
Did you try the same network adapter in the other Windows 7 Home Premium machine?

Please answer this question to help me understand the issue to help you better.

Hope that helps.

Resetting the TCP/IP stack (above) did not help.

Same free Avast I've been using for years on PC. I did try to disable the security protection for a short period as a test, no help.
Built-in wired connection is the bad one. Online now 'cause I shoved in a USB wifi adapter.

Thanks.

Check your adapter properties for the connection for IPv4 and IPV6.
Check default gateways are correct, or DHCP is enabled if that's what you're using.

Check and Install available updates and reboot.
Check for latest Network Card drivers in device manager.

Check Ethernet cable with another device to verify good cable.

CMD>
ipconfig /release
ipconfig /renew

Coldboot\Reset Modem.
Call ISP to verify outage in your area.

Give it a run.

No solution yet...  Issue seems to (be/mimic) a bad NIC.  Reminder: With a good static address (w/ proper gateway, etc) get "Unidentified Public Network".  With DHCP enabled get "Unidentified Public Network" and a 169.x.x.x IP address,

Check with static ip address, gateway and DNS address. if DHCP enabled get "Unidentified Public Network" and a 169.x.x.x IP address, check with ISP (Internet Service Provider) for connectivity issue.
