iMac does not connect to wireless network automatically when it starts

I just got a new Intel Core 2 Duo iMac 20". Everything is working great. I've been reading about people having problems with wireless connection with their Intel iMacs. Fortunately, my wireless connection works fine and the internet speed is fine too. The problem I'm having is that when I turn the computer on, it does not recognize the wireless network and connect automatically. Once I type in the Network Name/Password, it works great. Even when it wakes up from sleeping mode, it's fine.

When I turn on my PowerBook G4, it recognizes the wireless network and connects right away. I checked the setting on both computers and they seem to be same.

My goal is to turn on the iMac and have it connect to the wireless network without having to enter the Network Name/Password manually each time the computer turns on. I know it's possible since my PowerBook does it.

I searched the forum without any luck. Any suggestions will be greatly appreciated.

Thank you everyone.

Thanks, but As I say, if I can't log calls by email I'm stuck, I can't phone when at work (not in front of the mac), get home after they close and where I am, there's not even a computer shop/tube nearby.

I'm covered by Applecare, sure enough, had the mac for less than 3 months, but, sadly, travel by Bus and tube.
Ho-hum. As I said, I can take a day off in June. Will have to hang on until then.

It's getting a little worse too, I notice. Had to recconect a couple of times after it suspended on Sunday.

And has anyone else had this odd thing in Boot Camp running XP (I updated to the new version to try and sort it, but it's still bad), where the connection to your wireless box is saying it's ok, and you can ping things, but no internet browser shows pages?
Tried repairing, tried renewing...still won't show web pages.

Oh and the speeds lousy in boot camp too..starts at 11, sometimes, goes up to around 23...but still, I never get a 54g connection...

Tried slapping the old Linksys box in to check it wasn't my aiport extreme 802.11n, same thing, non 54g, lost the net after an hour or so...and all my powerbooks and the sony vaio are still fine.

Odd..
