If you are wireless, it's perhaps to do with wwhere the router is located or maybe the router is worse than the one before. If you are wireless, you can always try things such as moving the router into a more open space. Things like doors, thick walls and furniture can block of wireless communication which will result in low strengh, slowness or connection loss.
The other thing you can do (which applies to ethernet) is diable some Windows services. Not many know that Microsoft have added services that takes up internet to cause slowness in the background. It's services like sending information to Microsoft or enabled Telnet. These can be disabled by going to Run > Type in services.msc or going into your connection properties and disable by unchecking the boxes.
