Airport and Wireless Connectivity Issues on MBP

[DukeVu]

I've recently bought a 13" MBP 2.4ghz. At first, the wireless internet was working perfectly fine.

However, after 2 weeks or so i started to notice some odd issues. If the MBP has been asleep for a while and I wake it up, the connection is gone and I would have to reset the modem to fix it. That isn't a major issue though.

Now, I cannot get a wireless connection AT ALL. The airport status on top has all full bars but when I open up my network configurations in system preferences, it says that AirPort is not connected. When I open up Safari, it just states that there isn't an internet connection.
I've tried to connect it to a friend's wireless network, and no luck. I've resetted the both modem/router and the MBP, and no luck as well. I'm all out of options!

Does anybody have any suggestions?

The latest version (of OS X 10.6) is 10.6.4 ...

if you are on 10.6.4 - i believe this update did something funky to the Network Preferences. i noticed that for whatever reason my iphone (which is part of the airport network), was being prioritized as the internet connection, even though i was connected via ethernet and airport. i simply made that connection inactive. also check the airport connection priority; for me it's ethernet (if i'm connected physically), then airport.

Yeh, the internet on my iTouch works perfectly fine. So you're suggesting that i should re-prioritize my connection devices? How do I do that?

open network preferences either by opening system preferences or by clicking on the airport icon in your menu bar. the service list is on the left: airport, ethernet, local network (if you have one setup), bluetooth, firewire (if available). click on the gear icon below the list and select set service order.

I noticed something funky too. Whenever I add or edit a VPN connection it drops the wifi connection untill I'm done.
