Test an ethernet connection:
Self explanatory. Test if the issue persists on a wired connection to rule out the wireless adapter hardware so troubleshooting can be directed towards the right areas.

Test another connection:
Many people rule out their home network as an issue if another device is working on the same network. Networking is not that simple. Each device interacts differently with your router or modem and it is impossible to rule out settings in that device until the notebook has been tested on another network. . I will be glad to help you.

Please keep me informed of how things went. 

If you require further assistance, let me know and I will gladly do all I can to help you.

Hello,
I tried all your suggestions but when I go to device manager and click on the network card proprieties and select the "resource" tab I read the following:

Resource settings:
Insufficient resources to the device

To use the device, you must disable one of the other devices in the system.

My question is, which are the devices to deactivate?

If I use the network cable I can use the Internet connection but when I try to use the wifi connection I can't do it.
