Macbook Problem

Hi, New to this forum. Seem to have a problem, have looked through this forum before for answers but they ended up not being the solution

I will use my Macbook for a while, and the internet will be ok, but If I leave it inactive for a while, like I will get up to grab a glass of water, the internet will not progress. I end up having to go to System Pref > Network > Assist Me > Diagnostics, and in that window I will find that everything below ISP will fail, and this I would go thru diagnostics to fix it again. The problem is that I shouldnt have to be going thru this proces every time I dont press a button on the macbook. I find that If I leave a p2p site or a torrent site running, the internet is fine. Not too sure if this is a macbook, or an internet or a router problem, tho I figure its probably one of the latter 2.

Anyone want to help shed light on this problem. Theres a probably a quick explanation.

Thanks in advance.

My network is wireless through a D-Link Router, and from a previous post I read a while back Im not running dchp, and changed the router channel.

Im tried turning off and on airport, and even created diff location.

Never heard of MRoogle tho.
