Hi. I recently upgraded my windows to anniversary version last week and after several hours I notice that there's something about my wifi connectivity. I am 10 meters away from the router but the wifi indicator at the right bottom show full bar but my connection still very slow and it should be only 2 bar like before. After several munites of connectivity it disconnects itself and when I tried to connect it again it says that can't connect to this network sometimes no network found. I restarted my pc to and it connects again and disconnects again after 5 minuntes. Help me do dome something about this..
