I've been dealing with this issue for quite some time now and i thought i had it fixed but after tonight i am not so sure. Basically this laptop is about 2 years old. Its an Alienware 17 R5. It worked great for about a year or so, after that the WiFi started disconnecting randomly and most of the time during a stream or online gameplay. I have tried unistalling and reinstalling drivers, Removed the Killer networks Suite, I have tried making as little interference between the pc and the router and i have even swapped out the WiFi card. Nothing seems to solve the issues on this computer. My only other step is to wipe out the computer and start over. Does anyone else have a solution for this short of starting over?
