Win 7 can't connect to DSL cable

[dexter11]

I have a HP Pavilion dv-6 with Windows 7 64bit on it. The internet connection suddenly stopped working. Meaning the previous night it worked fine, on the next morning it's just not working.

Windows doesn't even notice if the cable is plugged in. The ethernet plug in the laptop used to flash orange while using the internet. Now nothing.
Troubleshooting the network adapter wrote that that cable must be broken. But it's the same cable I'm using now plugged into an old computer with XP.

I tried to install Connectify Lite on the night it still worked, but I uninstalled it immediately and the connection was still on.

I tried System Restore to revert the changes (Connectify install and a Windows update) that might have caused this.
I also installed a new driver for my network adapter (Realtek PCIe GBE family controller) from the Realtek website. According to Device Manager the Network adapter works fine.

Thanks for the info, you did great.

Would you mind disabling the Wi-Fi and bluetooth adapters for troubleshooting purpose?

You may also try resetting the TCP/IP and Winsock, see if it helps.
SG :: How to repair TCP/IP and Winsock

An update would be nice.

Sorry I was busy in the last few days.
How do I disable the wifi and bluetooth adapters? And how do I troubleshoot then?

I'll try that tutorial. Thank you.

No worries, I've been very busy as well....
Please follow this tutorial on how to temporarily disable any device from Device Manager.

How do I disable the wifi and bluetooth adapters? And how do I troubleshoot then?

Thank you for your help. It worked.

I made some changes since the last time. I couldn't afford to lose connection that long so I bought a wifi router. The wifi router is plugged in to the Paradyne bridge. But I still wanted to fix this issue just in case.
So I plugged in the cable to may laptop, disabled wifi and bluetooth in the Device manager then I used TCP Optimizer to reset TCP/IP and Winsock, rebooted and now I have Internet directly through the ADSL line too.
Thank you again.
