Also depends on your WiFi receiver in whatever device you use. I get 240mb download speed if I use an Ethernet cable but wireless I only get 130mb down. So you could get your badass spider router and not see any change. If you want to check your speed, wire up your computer or laptop and use this: Speedtest.net by Ookla - The Global Broadband Speed Test
Could also check your WiFi speeds with it too.
Dunno if you noticed but the WiFi receiver on the PS4 is atrocious.
