I think it would be pretty awesome if Netgear made their Network devices like the Netgear Orbi support the free software called Pi-Hole via an app/plugin support feature on the device itself. For tho...
The problem with this, is when the blocking of ads then breaks a website or an app. If the user (lets say your partner or child who doesn't understand this stuff). wants to use that site or app, but has no idea how to whitelist it. It isn't going to be user friendly to the house hold which is why it is always best for such features like ad blocking to be done on an individual device/user level. Netgear could develop a browser plugin to help manage it, but then you are talking a plugin that needs to work on multiple browsers, which is a hassle for what business gain and it still doesn't help for apps like Live Sport Tv (and similar) which will stop working with ad blockers in place.
