I started with an Amazon Prime trial period only to find that I have seriously depleted my limited data package very quickly. After a bit of reading I established that this is something to do with Amazon's default quality settings and that this can only be changed on- and according to the specific device that one uses. However, on my Samsung Smart TV I cannot access the Amazon app's own settings (some models are like that), which apparently only leaves one option and that is to limit the bandwidth on my router. Yet on the default router firmware I could just toggle between 20 MHz and auto, I could not set a download limit for a specific device/IP. Any advice? Otherwise I'll probably not continue with Amazon until I've sorted out my data infra-structure. With Netflix this is quite easy to manage.
