I've had the same powerline adapter for around 6+ years now and always fairly slow download speeds is it worth upgrading to a newer model? my current model is the TL PA411 which is up to 500mb/s and from just browsing i see they are significantly "faster" than this now. From looking around i see alot of posts mentioning that it also comes down to the homes wiring so im just wondering if replacing my current model will result in a faster download speed with my current speed on apps like steam being 2-4 mb/s
