Possible airport problem after update

[Holly Anderson]

Hi guys.  I ran the update for os 10.4.8 and I'm noticing an issue.   
Always before when I would check the airport status I would get 4 of  
4 bars, now it fluctuates a lot between 3 of 4 and 4 of 4.  Also when  
I check the status its slow to respond, and anytime I arrow around  
that menu when it gets to the airport status its very sluggish.   
Anyone else experiencing this?
