Ever since I upgraded to 10.5.2 I have constant network drops on my wireless network. What can I do to fix this? It is extremely annoying, to the point where I've been using my Windows desktop more than my MacBook. So what things can I do to try and resolve this. To be honest it is totally unacceptable and has be on the verge of installing XP just so I can reliably surf the internet again. Thanks in advance.
