assuming you have a PS/2 adapter on it I would say its not the actual connection but either the mouse or the wireless comm part. Make sure you have bateries in the mouse, if the red light is on or flickering the mouse has power, after that, on the bottom of the mouse is a reset button which will reset its connection with the base, hit that. The cordless opticals have quite a range on them, but make sure your not out of range. If all you're using is the PS/2 adapter (the mous eis USB but packed with adapter) there shouldn't be any driver/software issues that didn't exist with your previous mouse.
