In this case, your WiFi is not faulty! This usually happens when the SSID has been changed.
Explanations:
SSID (Service Set Identifier), is the name assigned to the wireless network (for identification purposes). When you connect to a wireless network and choose to save it, the SSID and the security key of the network is stored in the PC in the "Wireless Networks Manager".
This allows the PC to automatically connect to the Wi-Fi network, when available.
If SSID is changed, the PC recognizes and connects to the modem, but internet won't work because of a conflict between the old SSID and the new on (both stored on your PC).

Reset the SSID:
The solution is quite simple, just delete the old SSID from the list of networks in the "Wireless Network Manager":
Open the Control Panel > Network and Sharing Center
Click "Manage wireless networks"
In the window that opens, select the network with the old SSID and then click on "Remove".
