Wireless driver question

[Rajagopal K N]

Hi - I have a IBM ThinkPad R40 laptop running windows XP. 
  When I press the "Fn F5" key to turn-on the wireless, There is 
  no pop-up menu that show-up to turn-on the wire-less. Is this because 
  software driver not installed properly? How do I fix this? Is there a
  driver that I can install to solve this?
   
  I also don't see the battery power% indicator showing-up in the task bar.
  How do I fix this?
   
  Thanks,
  --Rajagopal
