What does it take more to receive firmware

I bought a Archer C6 two days ago.after connecting it to my laptop through ethernet port the internet speed is very low.its taking much time like 15 seconds to load a website.i have a 50mbps internet...

I want to buy a tp link router but I'm stuck at deciding between Archer C6 and Archer C60 as both cost the same on Amazon.i'm very confused.which one is the latest.can anyone tell me which is better...
