Intenet connected but server not found

[fansgirl]

Recently I re-installing my windows 7 on my netbook, and since then my internet connection have some problem.

Sometimes my internet connected and I can browsing just fine but it always go to server not found when no activity for about an hour give or take, I don't actually counting it but today 5 times server not found happening.

I'm using my home wifi, and it not my wifi is trouble because I can connect just fine on my smartphone.

my firewall is down, and I'm using kaspersky, but when I just reinstall windows my internet connection glitchy like this too.

That's working is it the same when you get the error. Disable ipv6 set DNS to 208.67.220.220 & 208.67.222.222

Ps. Before I reinstall windows 7 my wifi down just like this and when I put fd which contain myfile before I reinstall my netbook on my mom laptop that laptop got error on internet connection too. And no after I reinstall windows I'm not put that fd on my netbook atleast for a few days
