Cant acess internet.

[gods_hammer]

Hi I have a problem with internet. While LAN cable works and everything is pluged in (windows says internet is working fine) I cant acess internet no matter what. Now I think I deleted something, because I got ambushed by YouTube accelarator, and it got installed. I couldnt un install it, so I got Revo uninstaller and deleted it somehow, now after that I just cant acess internet anymore. Ive reinstalled internet drivers and still nothing. Now, when I open Device Manager, Network adaptera, I see that TEREDO TUNNELING PSEUDO-INTERFACE has yellow mark and its not working, error Code 10. Could that be reason why my internet is not working ? Any ideas ?

Yes, that is why your internet is having issues, and luckily(or unluckily) this is something that is known to happen occasionally with this MS driver. Here is what you will want to do to fix it:

 

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. It should now be present without error.

 

This should resolve the issue - if you still see an error, then there is one further step to take:

 

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, right click Disabled Components and select edit.  Set the DWord value to "0" -  Then reboot computer.

 

EDIT:  -----The following commands fixed the OP's problem(after fixing the teredo protocol)-----

netsh winsock reset catalog

netsh int ip reset reset.log hit

10. Scan for new hardware

I cant find that, I go under action and see only Scan for hardware changes and Add leagcy hardware, and when I select show hidden devices Teredo Tunneling is not there

[Bonesy]

Scan for hardware changes is what you want, and you might need to go to View>Show Hidden Devices to see it

Great news, Teredo tunneling is working under hidden devices, bad news internet is still not showing up.

Have you rebooted the computer? Also, double-check that on the teredo adapter, both IPv4 and IPv6 have it set to acquire settings automatically under the device properties

Funny thing, when I open Local Area Connection it says

Ipv4 Connectivity: Internet

Ipv6 Connectivity: No network access

?

Yes, this is normal - Have you rebooted the PC and double-checked your network adapter has both IPv4 and IPv6 set to acquire settings automatically?

 

If so, then your drivers are working accordingly, and we now know it's software causing the issue. Do you have McAfee installed? This is the usual culprit.

Have you tried connecting any other devices?  Have you switched routers recently?

Ive rebooted PC, but how can I checked ipv4 and ipv6 are set ?

Internet works fine, I think I ruined it by deleleting something.

[gods_hammer]

Well if everything goes beyond repair, I will have to re install windows ?

Right Click your adapter and select "Properties". Scroll down to the bottom of the new window that opens up, you should see the following: http://i.imgur.com/MnIPEdp.jpg

Click Properties once IPv6 is selected, this will open up another window - in this window make sure he top checkbox for both sections are checked: "Obtain address automatically". Do the same for IPv4.

This is not an issue that requires re-installing OS. Just takes a little patience to determine where the problem is coming from. We have fixed your teredo protocol, now we need to find out if your IP configuration got changed also and needs to be fixed. I have sent you a private message with other options.

[gods_hammer]

Both ipv4 and ipv6 are marked as check so I guess they are working, I will PM you cus right now I have to go.

Thanks m8 for everything btw.

Is there still the issue with the apparent malware on the computer? If so I can help remove that easily.
