I have really poor WiFi signal in my bedroom, which is on the second floor in the front of my elongated house. I keep my WiFi router in the utility room, which is on the first floor, more to the back of the house.
I know for sure that the problem is in WiFi reception because when I bring the computer close to the router, the connection is really fast. I am using a 300 Mbps Medialink N Broadband Router.
