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

[Keggers]

Hello, I'm seeking assistance to get connected with my pc to the Internet as I need it for work.. All of a sudden it has lost it's connection and when I run windows network diagnostics it reports
" there might be a problem with the driver for the local area connection".

All my wifi devices work as normal.

I have tried several reboots of the router and changed the LAN cables around but no difference.

Any help much appreciated.

Thankyou.

Welcome to Seven Forums,

Can you please provide an ipconfig/all output for review by following this Tutorial?

Also, do a snip of your Network Adapters in Device Manager make sure to expand it and post it here please.

Hello again, I've tried to attach a screen shot of the ipconfig/all via my ipad as I don't know another way. Hope it works!

Connection type : wired
Provider : aol now talk talk I think
Broadband type : dsl
Router type : huawei echo life hg532
Antivirus : avg
Firewall : windows.

Ipconfig didn't show me much compared to the example in the tutorial,, looks like I don't have an IP address.

Hope this helps.

Also the network adaptor is a Realtek PCIe GBE Family Controller. I can open it up but shows me 7 different titles for the properties,,details,resources,power management,general,advanced,about,driver.

Do you need any of this info?

Thankyou.

Will I be able to fix this or is it beyond repair?

Your problem is that you don't have a LAN connection; with ipconfig/all you should see "Ethernet adapter Local Area Connection:" You either have a hardware problem with your LAN connection (it could be physically dead). That's the less likely scenario of two. Most likely it's a driver issue. Go to start -> right click computer -> manage -> device manager (column on the left) -> find your LAN connection and uninstall it. Right click in that same window and choose "scan for hardware changes". Let it automatically find and install the driver. If that doesn't work you will have to download the drivers with another computer, drop them on USB, and install on the non-working computer.

Not only do you not have an IP address, there are no network adaptors showing up here at all.

You didn't post the screen shot of the Device manger with Network Adaptors expanded.

Sometimes shutting down completely and removing power then pushing the power button to drain all power then restarting will make the adaptors visible again.

Tried all this twice, no change!!!! Also downloaded drivers from the net and they never helped either...

I am now thinking my Ethernet card is dead!!! Would it be best to just purchase a new one and give it a go?

When I see things disappearing like this then there could be some system file corruption or more unlikely is hardware failure.

To check the system files open an elevated command prompt and type or copy/paste> sfc /scannow then hit enter, let the scan run and see what it says when it's finished.

Thanks, I'll try that in the morning and report my findings.

Hi there, I have done as requested above and I attach a photo of the results, not sure what it means though...

I entered the wrong command and have re done the scan and posted the results.

Well it's not a system file problem which would have been an easy fix.

Try running the file below, it will reboot your machine after it resets the network stack, please post the ipconfig/all again after the reboot.

Hi chev65

I ran the file below and post my latest ipconfig/all results although I think there's no difference from the first try,

Ok then we know it's something on the board or it's hardware related at this point.

Are you able to access the cmos on this machine in order to clear the cmos and reset the board?

That was quick chev65, I'm sorry but you will have to explain a little further. The cmos?

Hi chev65, CMOS cleared I believe, this is a screen shot when powered up.. What next?, thankyou.

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?
