Hi. I'm a Macbook Pro user running OSX Ver. 10.6.8 and I've recently encountered some trouble with my wireless internet connection. Occasionally, I am unable to connect to the internet. However, if I turn Airport off and then on again, it works fine. None of the my other devices have this problem -- just my Macbook. What steps should I take to ensure my computer regains its stable wireless connection? Thanks in advance!
