    Default AU MacBook wireless card now set to 'US'?

    I've been having issues recently not seeing my wireless connection. I managed to track it down to my MacBook not being able to see wireless channels above 11.

    My Airport was always set to Channel: Automatic, so it was selecting and broadcasting on 12/13 which I've always been able to connect to.

    Apparently my MacBook now no longer can see channels 12/13 and has changed to a US Airport card rather than AU (purchased in Melbourne, AU).

    6/03/09 6:45:41 PM kernel en1: 802.11d country code set to 'US'. 6/03/09 6:45:41 PM kernel en1: Supported channels 1 2 3 4 5 6 7 8 9 10 11 36 40 44 48 52 56 60 64 149 153 157 161 165

    From a few days ago, it supported channels 12/13

    4/03/09 6:23:14 PM kernel en1: Supported channels 1 2 3 4 5 6 7 8 9 10 11 12 13 36 40 44 48 52 56 60 64 100 104 108 112 116 120 124 128 132 136 140

    I've tried turning airport card on/off, zapped PRAM, and can't think of much else to try?

    System Profiler says:

    Wireless Card Type: AirPort Extreme
    Wireless Card Locale: Asia Pacific
    Wireless Card Firmware Version:
    Current Wireless Network: ckAirNet
    Wireless Channel: 11

    Any ideas?

    One thing I can say is don't worry too much about the USA card I.D.

    I have a US sourced card in my iBook and was initially concerned about it when I looked it up in System Profiler. But, it hasn't caused any probs.

    As far as anything else goes, I can't enlighten you, sorry.

    Maybe a re-seat?

    Someone's bound to come along.

    Just annoying, System Profiler says it's 'Asia Pacific' but I can't connect wirelessly to my usual settings, as my Airport Base Station was set to Automatic channels and set itself on Channels 12/13 which my MacBook now can't see.

    Haven't had to worry about my wireless for about 3 years till now...

    I'm having the same problem atm. that coupled with the fact that the airport card doesn't support 40mhz on the 2.4ghz band is leaving me pretty frustrated.
