Bought a new Razer Bluetooth mouse to go along with my Razer Blackwidow Ultimate keyboard.
At first, it would not connect at all. The OS, (Win 8.1), says it was searching for any Bluetooth devices, but it would never detect or pair with the mouse. When looking for something on my desk while trying to get it to work, I set the mouse down within about one foot of the computer case. It found the mouse and paired with it.
It works as long as the mouse is kept within a foot of the case, and with nothing between the mouse and the computer. Any way to improve the range? Is there an antenna that I can connect to increase the range?
