my isp has add on plans that can supposedly know if im using an xbox, certain games or a ps.

how do they detect this? And is there a way to, for example, use the playstation bundles on xbox? (they offer more quota)

If you are using your ISPs device as your router, they see the MAC (hardware) address of each device on your wired and wireless network and know the make of each.

If you substitute your own router, the MAC isn't passed through and they'd have a tougher time knowing exactly how many and what kind of devices are in your home network.

Additionally, some routers (and all OpenWRT routers) can run a "full tunnel VPN" client, obfuscating your traffic from your ISP's deep packet inspection and preventing them from enumerating your internal clients.
