Mac users please help me :)

Hello,

I have a problem when waking up my Macbook Pro, I can not connect
to wireless at home (from time to time). It takes me several times to
close and open notebook to connect. The problem is only at home, I have
tried three different Wireless APs. My iPhone and other notebooks have
no problems connecting at all. I am certain that problem is not with
APs (I’ve tried to change channels, etc.). What I think is a problem is,
that sometimes Airport card wrongly detects country code and reverts
to a few channels. This is from the logs – unsuccesful connection:

Also, I was not able to find current Airport Express firmware update for
10.6.1. The last one I found on Apple.com pages was 2008-004 (which does not work on 10.6.1), so I’m not sure if I have the latest firmware.

MacBookPro4,1   Mac OS X (10.6.1)   Card type: AirPort Extreme (0x14E4, 0x8C), Firmware: Broadcom BCM43xx 1.0 (5.10.91.19)
