Hey guys, It's me again, and i need your help 
I have D-Link Dir-300 router, and i have a big problem.
I use cabel internet. Cable comes to router, then with other cable to my Personal Computer, and wireless to laptop. So the problem is that laptop's internet is lagging. It is turning off after some time. For example i am watching youtube, and movies stop loading, google stops working, and firefox gets offline. I don't know what to do. I tried rebooting the router and changing cables, nothing. I dont know.
Please help,
-Wooxie.
