Fast internet connection/ping - but slow browsing

[SyntaxDZN]

Hello, I've been experiencing some browsing issues regarding the speed of it.
I recently (few months ago) bought a new router (netgear AC1900 R700) and adapter (TP link).
Now I've never come across any problems with my previous router (except slower download speeds), but now that I used this one, I notice my browsing speed being EXTREMELY slow, resulting me in having to restart my browser everytime because it's being too slow.
BUT my download speed is very good

I've tried:

• 
  -Flushing my DNS
  -Changing DNS to OpenDNS
  -Changing MTU value

I've seen some awnsers on forums about this issue, yet none seem to work, any ideas?

Thanks!
