Wifi and ethernet problem

Right. As you have told that you have your driver adapter is up-to-date, I'd still suggest you the following.

Step 1: Uninstall network adapter driver.

• Open Device Manager by clicking the Start button, clicking Control Panel, clicking System and Maintenance, and then clicking Device Manager.
• If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
• Look for the Network device under Network Adapter option, right click on it and select Uninstall.
• Reboot the computer.
  

Step 2: Download the latest network adapter driver from the manufacturer website and install on it your computer.

Your problem could be also linked to Windows Update. Your computer might have auto-installed an update which is causing problems with your internet. You'll have to look for the "bad" update that is causing it.

Go to control panel -> System and Security -> Windows Update

In that section you should find the "bad" update and delete it. You may have "important" or "optional" updates, check them if there's any "garbage" updates, hide it through right-clicking and selecting "Hide update".

Selecting View Update History in the Windows Update section, you should be able to view updates that has been installed onto your computer. If you have just got this problem, I'd suggest to check the recently installed updates. Select the "Installed Updates" from the page, and you should arrive in a page that has many updates in it. To delete an update, right-click on an update and click "Delete update".

If this works and you want to prevent this happening in the future, change your settings in the Windows Update, Settings section and changing the option to "Check for updates, but let me choose whether to download and install them."

Other suggestion;

Go to "manage WIRELESS networks" in Network and Sharing in the Control panel.

Delete the wireless connection made to the router - this will trick your machine into thinking that it's never connected to the network.

Go to "manage networks connections" and right-click on wireless.

Connect to chosen network and check "display characters", you can then see what is your entering to cross reference with the wireless key.

That should then connect - if not, reset the router (pin hole in the back until lights change)

Follow the same process - you will need to reconfigure router with your ADSL UN +PW

Hopefully you'll find the solution!
