But when i connect my laptop with Ethernet cable it works fine.

Please help anyone know what could be wrong?

Thanks.

Sounds like there is a problem with your router. Try shutting it off for 30 seconds and turning back on. It could also be because someone changed the router password if you have one or maybe your ISP suspended parts of your service.

Ask to see if any of your family members have used the router control panel to modify any settings, if they have not then log yourself in while connected to Ethernet and double check the wireless settings you have and mirror them to all your devices.

Do as Boxty said. Also, if that doesn't change anything, call your ISP and explain the issue.
