Hello everyone. Ever since I upgraded to Windows 8 I have found that my Wi-Fi signal became weaker. When I still had Windows 7 there was usually 4-5 bars, but not it's reduced to 2-3 bars at all times. In terms of hardware, I do not think I have changed anything. I'm a bit frustrated because i can't think of a solution and the change in internet speed is definitely noticeable . What am I missing? Please help!
