This method will hard reset the wireless drivers back to default settings, but before you perform this remove power from the modem and router for 2 minutes reconnect power and wait another 2 minutes for them to settle down.
Go to your laptop, right click "computer" select "manage" and then "device manager", a list will populate, then click on the + sign next to "network adapters" and right click on the wireless adapter and "uninstall" the device, reboot the PC and wait for windows to detect the wireless card and install the drivers for it, this will appear in the system tray (bottom right hand side) when its done try to connect again.
