Problem with connection (Mac OS X)

Hello, I wasn't sure if this should be in Mac section or here, but hopefully I got it right since it's a problem with Internet connection. Anyway I have a strange problem with Internet that stops randomly working every few seconds, like it freezes for a second. For e.g. I usually have to enter the button "Enter" twice before it starts opening the page. Speedtest shows good results and I don't seem to have the same problem with my laptop (which is running on Windows 7 Ultimate). I will paste the ping results I got, oh and by the way, it's OS X Snow Leopard if that is important in any way.

Here are the ping results:
