Since I have owned my 2.2 Black Macbook I've been plagued with horrible airport connectivity issues. Not matter where I was located, what AP I was using the connection would be very slow and extremely unstable. So I decided to take it into the Apple Store today, my girlfriend was taking her Macbook in for battery issues so I figured what do I have to loose. He went through the logs in Console, asked me when I last had this issue. He pinpointed when it was occurring and found a few messages from something called 'vmnet'. He saw I had VMWare installed on my machine. He start terminal and began to ping ping Google, 15ms response time, then started a virtual machine with VMWare. Pings skyrocketed to 600+ms. He went on to say that VMWare does some funky things and it is more than likely the culprit. I left there mildly disappointed that he simply wrote it off as a software issue, something I would expect Dell or HP to tell me. Frankly I was waiting for the response to format and reinstall, but thankfully I have moved up in the world. So I got home tonight, sent VMWare on its way to the trash, I figured its easy and worth a shot. VMWare wouldn't delete from the trash so I decided to check out AM for any running processes, sure enough there were 5-6 'vmnet' processes running. Ended all of those, deleted VMWare from the trash and holy cow I'm surfing faster than ever. I can't believe it was something so simple and took so long to remedy but I love my MB more than ever now! I hope this helps anyone with this issue out!
