Maybe its the military using your wireless connection to access your computer so they can transmit spy information and have it traced back to you and you'll have your door kicked in by ninjas working for the ATF and go to prison and they'll plant info on your computer that you sold weapons tech to the Chinese and N. Koreans.

Can't argue with that logic, ninja's are always to blame.
But in all seriousness I would guess it's because it is wireless. I used to have a Wireless Mouse/keyboard and I would have similar problems that your describing, which all went away when I went and got a new Wired Mouse/keyboard. Have to love shielded wires.
