I recently got a new internet package of 100mbps and my parents computer which is hard wired from a netgear R6300v2 is showing 114mbps down. My powerline adapter is a TPlink av600 and when I run the TP link software on my pc it shows a powrline rate anywhere between 70-90mbps but when i run a speed test i barely get 30mbps down. I've also changed the QoS from online gaming to internet and there is still no difference in speed. I was thinking about getting a netgear R6700 to see if this helps since my router is so outdated.
