add bandwidth manage feature

Hello. I am a user of R6120 model router. This router is basically an home based dual band wifi router that is best for home wifi. But this router don't have speed bandwidth manage feature but I think every of like this router should have this feature. All the router of other company have this feature. But in this model router of Netgear don't have this feature. But it's a very powerfull and good router so this router should have this feature. I am requestion to the Negear autority for add user bandwidth manages feature in this router.

Thank You
