Hello,

I have Lenovo G550 with windows 7! It shows that the Internet is connected but the IPv4 and IPv6 connectivity says no network access. I updated and reinstalled drivers, typed in some cmd command and restarted computer with no success. I also called tech support and they had me go into safe mode, the Internet didn't work there so he said it was a driver problem but wouldn't help me fix it because I didn't have two hundred dollars. Also when I connect the Ethernet cord i get the same message and the other computer in the house is working fine. Please help! Thank you

Were you ever able to connect this computer to your router by wireless? By ethernet?

Try to connect (at the same time) by ethernet and wireless and show ...

Start, Run, CMD, OK to open a command prompt:
(For Vista or 7 type CMD in the Search box after Start)

Type the following command:

IPCONFIG /ALL

[Note that there is no space between the slash and ALL.]

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If necessary use a text file and removable media to copy the results to a computer with internet access.

What firewall or security suite are you using?

(From a JohnWill post)

TCP/IP stack repair options for use with Vista or 7.

Start - All Programs - Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

Reboot the machine.

You're welcome. :) Guess I don't need to tell you to uninstall it and run the Removal Tool. It was probably just corrupted and, if you want it, you should be able to install it again and be OK.
