RealTek RTL8168

My client has got a RealTek RTL8168 10/100 PCI Express card in his computer, but in the Device Manager there is a yellow exclamation mark next to the entry 'Microsoft 6to4 Adaptor', which is disabling internet access. How can I solve this problem?

 

By client do you mean that you are a tech and this is a job?

Have you installed the drivers?

 

Yes I am a tech and it is a job.

He has got a RealTek RTL8168/8110 for Vista and that is okay under Device Manager. The drivers are installed; it just won't communicate with it

 

My client told me today this only happened since he left Pipex (they cut him off, I don't know why) and changed to Sky BB last week, they checked the line, the software is installed, here is a list of what I did:

I updated the network card driver to the current version
I deleted the 6to4 adaptor
I disabled IPv6 - I enabled it again when it wouldn't connect
I tried all 3, 'Never Dial a connectioin', Dial A Connection when a network is not present' and 'Always dial my default connection' which is 'Broadband Connection'
I uninstalled the network adaptor, rebooted, and got Windows to autodetect, that didn't work

When I click on Diagnose and Repair, it says there's a problem with the network card, but it doesn't tell me what! But then when I try to connect normally and diagnose, it says everything is working fine.

 

If it's helpful, it's error 814: The underlying Ethernet Connectivity required for the broadband connection was not found

 

Even though I put a network card in, it still didn't work. When I go into the corresponding LAN connection, the problem lies in the fact that ipv4 and ipv6 connectivity say they're not connected. How do I enable both of these?

 

I tried repairing TCP/IP but to no avail.
When I did an ipconfig /release (and ipconfig /renew) it comes up with the error message 'An error occured while releasing interdaxe Loopback Pseudo - Interface 1 - The system cannot find the file specified.
The operation failed as no adapter is in the state permissible for this operation.'
I have flushed the DNS, made sure Winsock wasn't corrupted, disabled IPv6 in the LAN properties and the Registry, but it still reports that ipv4 and ipv6 (even though disabled) has no connectivity. The problem is definitely with the new protocol (there is a bug with Vista and newer devices). Anybiody know how to solve this problem.
If it helps I have attached a ipconfig /all

 

Bl***y Microsoft!

That didn't work either!

The problem lies with ipv4. On the properties page for the LAN connection, it says ipv4 connectivity: not connected; I need to know how to connect.

This is a common fault with Vista, well documented on the web, but guess what? Microsoft won't help because Vista came preinstalled with the computer, and they want to charge £40 for support!
