Ok the wireless mouse u can usually adjust In Control Panel -> Settings -> Mouse. The keyboard problem sounds like it could be A) dirty or B) IR interference which could be caused by the mouse since it sounds like theyre 2 different modules, when it is recommended u get a packaged deal mouse and keyboard, this prevents the interference from eachother. However, other home appliances can cause the same problems. IR laptops remote controls etc. A good way to check it to use a a video camera with IR nightshot. Turn off the lights and look for blinking lights around the room.

Hope this helps
