New laptop, extremely slow Internet

Hello, I've recently got a new laptop, It works great. 0 Lag problems for anything, no freezing, it has decent speed and it seems to be better in every way compared to my previous laptop, however the internet is terrible. It takes 10~ seconds to load google let alone search something and it takes forever for a 10 minute youtube video to load on 360p. I can only assume that my computer does not get along with my router. Can any of you please help me fix this issue? Everything would be greatly appreciated! Thank you very much.

I'd like to add that at moments it has really good connection but about 90% of the time it's as I said above.
 
We will need lots of hardware and setup info to do you any good
  • version of windows
  • make + model of your modem and router if any
  • your ISP connection is ADSL or Cable? to which ISP
  • how are you connected to your modem or router? wired or wifi?
get on line and then
get a command prompt and enter IPCONFIG /ALL >myTCP.txt
open myTCP.txt and copy/paste that information into your follow-up response.
