I recently upgraded to Windows 8 but my LAN network is not working. In the network troubleshooting it shows this:

enter image description here

It worked well earlier.

I tried changing the DNS server to google's DNS (8.8.8.8) and it is still not working.

Can you ping your router. If that works, try pinging a machine on the internet by IP address. (Ping 8.8.8.8 would do.). If that does not work then you probably do not have a working internet connection. –  Hennes Nov 1 '12 at 18:39
    
What do you see if you open an command prompt and type ipconfig /all ? –  Joel Coehoorn Nov 1 '12 at 18:39
    
Also, try disabling IPv6, and if you use anything from Apple, look for a service called "Bonjour" and try disabling that. [edit]In fact, as I think about it this sounds enough like IPv6 that I'm gonna add that as an answer. –  Joel Coehoorn Nov 1 '12 at 18:40
    
I can ping computers in my own network but not outside. The network works on other comps. –  Harshil Mathur Nov 1 '12 at 18:44

I had bumped into a similar problem. This solution worked for me.

Check your default gateway using ipconfig (type ipconfig in cmd). If your default gateway is set to 0.0.0.0 then you must remove it.

Type route delete 0.0.0.0, that should work.

If not type netsh int ip reset c:\resetlog.txt followed by netsh winsock reset c:\winsock.txt. Restart your computer, that should work.

Also disable ipv6 to be sure.
