My HP ultrabook has been accessing the internet both through wireless and an ethernet cable until last week. For some reason it just stopped recognizing the ethernet cable. I really would like some assistance because I use it mostly at the halls of residence where my internet connection is through an ethernet cable. Please help.

is the wireless still working

what error do you get - cable disconnected or a red X on the ethernet connection symbol - bottom right of screen

with a cable connected - can we see an ipconfig /all
------------------------------------------------------------------------
ipconfig /all
If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post the results in a reply here.
Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.

If you do not have another PC - do you have a phone connected to the internet - can you photograph the result and post the image in a reply
Note: you will see entries named Tunnel adapter Teredo Tunneling Pseudo-Interface: we dont need to see that information - JUST the infomation above those entries

We would like to see the results from an ipconfig /all - post back the results in a reply here.

This should work for all windows version, XP, Vista, W7
Hold the Windows key and press R
For Windows 8
to open a Cmd Prompt or an Administrator Cmd prompt from the Desktop. Use Win + X and choose Command Prompt or Command Prompt (Admin) from the list.

then type CMD

then press Enter to open a command prompt box
(A new dialogue box - black with white font, will appear on screen ):

In the command prompt window that opens, type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

ipconfig /all > network.txt & network.txt

It will export the results into notepad and then automatically open the notepad and display on your screen.

Now all you need to do is copy and paste those results into a reply here
to do that:
From the notepad menu - choose Edit - Select all
all the text will now be highlighted
Next
From the notepad menu - choose Edit - Copy

Now go back to the forum - goto the reply and then right click in the reply box and paste the results.
The results from the notepad should now appear in the forum reply.

Uninstall and allow windows to re-install the adapter and Driver
goto the device manager > Network Adapters > click on the [+] to show all the adapters

right click on the adapter and from the menu

remove/uninstall the adapter

Now restart the pc and allow windows to detect new hardware and re install the adapter and the driver

Still no luck. Thanks for your help, I think it's best I take it to the supplier. Once more, thanks a lot for your time.
