Solved No Internet on desk top but all wifi devices work perfect.

You might want to check the Date/Time settings, it says they aren't set for some reason.

Pressing the Delete button should get you to where you can set the date/time, might have to look around a bit in bios, then load defaults and start up then post the ipconfig/all to see if anything has changed.

Do you have Zone Alarm installed on this system?

Let me look around for more solutions,:

If the yellow exclamation is still showing for Teredo tunneling then try the following.

1. Open command prompt with administrator credentials (Find CMD and right-click - Run as Administrator).
2. Enter netsh environment. Type "netsh" and ENTER.
3. "int teredo" and ENTER
4. "set state disabled" and ENTER.
5. Open Device Manager and uninstall "Teredo Tunneling Pseudo-Interface".
6. Open command prompt with administrator credentials once again.
7. netsh + ENTER.
8. "int ipv6" + ENTER
9. "set teredo client" + ENTER
10. Open Device Manager and Scan for new hardware.
11. Select "Show hidden devices" from the View menu. You will now see that it is present without errors with any luck.

Option#2
If the item is disabled.
In the start menu search bar type in REGEDIT to open the registry editor. Navigate through the following:

HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\SERVICES\TCPIP6\PARAMETERS.

In the right pane look for Disabled Components, right click Disabled Components and select edit. Set the DWord value to 0. (If you do have Disabled Components there, the value may for example be set to ff which is invalid.)

You must Restart your computer and the teredo tunneling adapter will now start.

Hi, I'm at the uninstall teredo part but can't find it in devices?

If teredo is already gone then go to the next step at the command prompt.

Hi chev65, in device manager I can see the realtek pci GBE network adaptor, does that require deleting?, I've never noticed teredo tunnelling adaptor.

Option 1 no better!!!! I'm on option 2 now and stuck at this part.....I've opened upto tcpip6 parameters, what do I do from there?

Cheers.

Let me check what the defaults are supposed to be for Windows 7, you aren't showing disabled anything so there may not be a problem here.

Yes you should uninstall the Realtek network adaptor in Device Manager then either reboot or right click and scan for changes, either way it will reinstall the driver.

Update: the registry on your machine appears to be missing some registry values for IPv6 parameters.

After reinstalling the driver can you post a screen shot of the properties for the Realtek NIC just to make sure that IPv6 is present and enabled.

This is what the TCP/ipV6 registry values should be so you are missing two keys here.

Ok, I'll try that now, thx

Hi chev65, I've tried all that, removed, reinstalled, no difference, done an ipconfig/all and attach findings,, seemsvless info than previous time.

 

[chev65]

I think the problem is in the registry which if that is the case won't be something I can easily fix because there is no telling how many other registry keys are missing.

Have you tried using system restore yet?

Or as a last resort a repair install.

I have tried system resored but it keeps saying it was unable to complete it!!!

Yep that's what everyone says about using system restore which is why having a system image is the best way to back up your system.

This system will require a complete reinstall of the Op system unless you have a good back up of your registry from when it was working. This is way past a networking problem IMO. :sarc:

Reinstall in progress!!! Using the option that backs up my files to the c drive with fingers crossed before I do a full on reinstall... Fingers crossed, I assume if these options fail the network adaptor has died?

The adaptor could be dead although with the missing registry keys and the missing network interface it's more likely that the registry is the problem and hopefully that is the only problem.

At last, I'm back on, just the hell of re installing all the software..... Many thanks to you chev65 for your patience,, how this happened ill never know I guess!

Hey it happens to the best of us, somehow the registry was missing keys and this happens pretty often but no telling how.

At least I know when to throw in the towel and I was pretty sure it was just a registry problem since you passed the system file integrity test. Glad you are up and running again.

It's very good of you chev65, us minions would be screwed without the help of your kind. Thanks again for your time and patience...
