Your ISP may be a victim of DNS poisining... Did you try to consult the ISP regarding the problem you are facing? What excatly happens when you say its a dns problem??

The problem is of dns for sure. I don't get redirected to some websites, and sometimes, i get redirected to a wrong website... Sometimes the connection just drops...

That may be a problem of ARP Poisoning... Go to command prompt and type :

arp -a

if there are many IP listed, just renew your IP Address and that mey get your problem solved, I don't know what is the command for linux. The linux command for dns cache flushing is :

sudo /etc/init.d/nscd restart

I don't know how to do it in windows.. may be just renew the ip...
