Hello everyone.

I'm new to the forums, but not to Apple. I have done software development in Xcode (refer the USB Missile Launcher) etc.

I want to post a message to this forum to see if anyone else has come across this issue and if it has been solved. I have searched the forums without luck.

I have the new Airport Extreme that is 802.11n capable. I have successfully attached an external hard drive and printer. And I have run the 802.11n enabler on my MacBook Pro.

The base station is configured currently for Wireless Access on "802.11n only (2.4 GHz)" and I can access my network via the Airport base station using my MacBook Pro. However when I change the base station configuration to "802.11n only (5 GHz) the MacBook Pro can see the network but is unable to connect to it.

I have tried the same test with my wife's iMac 20" and she can successfully connect to the 5GHz network.

Does anyone have any idea what's going on?

System Profiler has the following details about my network card:
Wireless Card Type: AirPort Extreme
Wireless Card Locale: Asia Pacific
Wireless Card Firmware Version: 1.1.8.5
Current Wireless Network: [network name deleted from this posting]
Wireless Channel: 13

    David, Welcome to the discussion area!

    Since your Mac is still under warranty, I would contact Apple. The issue you are having is very likely a hardware failure.

    David,
    It may be that the MacBook Pro is using the 2.4GHz AR5008E-3NG chipset rather than the 2.4/5 GHz AR5008E-3NX chipset. Unless this has been changed with the new 2.2/2.4 GHz MacBook Pro models, I suspect that Apple doesn't actually sell a machine which supports 5 GHz 802.11n wireless. Linksys supports 5 GHz on their WRT-3x0N wireless routers but that feature is undocumented in their specifications and user guides. Their new WRT-150N router only does 2.4 GHz 802.11n wireless.

    That is incorrect. The initial Intel Macs contained hardware which works with 5 GHz wireless networks. The Core 2 Duo Macs and Xeon Macs have 5 GHz 802.11n compatible hardware.

    I don't have my MacBook Pro handy. Does the System Profiler report if the chipset is a AR5008E-3NX? I could understand them going with the 2.4 GHz chipset since 5 GHz takes a more power to generate.
  • Duane Level 10 Level 10 (117,950 points)
    I don't have a MacBook Pro handy either.

    As I mentioned above, the initial Intel Macs contained hardware which works with 5 GHz wireless networks. Many users discovered this when they booted into Windows or used Linux. Initially there was no support in OS X for 5 GHz usage.

    Also reference Does the MacBook Pro support 802.11a? which is only one of many sites which document this ability.

    See the MBP doesn't tell me what the chipset is. How do I find out?

    Some updates to report.

    This evening A friend and I conducted some more tests using his brand new 2.2GHz MBP.

    Specs as below.
    Hardware Overview:

    Model Name: MacBook Pro
    Model Identifier: MacBookPro3,1
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2.2 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2
    L2 Cache (per processor): 4 MB
    Memory: 2 GB
    Bus Speed: 800 MHz
    Boot ROM Version: MBP31.0070.B00
    SMC Version: 1.16f8

    AirPort Card Information:

    Wireless Card Type: AirPort Extreme (0x168C, 0x87)
    Wireless Card Locale: Asia Pacific
    Wireless Card Firmware Version: 1.1.8.5
    Current Wireless Network: wireless network not available


    So we updated the configuration in the Airport Extreme base station for both the tests below.

    Test 1
    802.11a - MBP 2.2GHz - successful connection
    ioreg -n -b confirms 5GHz band, channel 36, 54Mb/sec

    Test 2
    802.11n ONLY 5GHz - MBP 2.2GHz - Can see network
    Error connecting
    Console.log reports "WirelessJoin unexpected status: 8" for every failed attempt to join the network.


    On both my MBP (2.16GHz) and his MBP (2.2GHz) the specs from the terminal command "ioreg" are the same. This command was performed when the machine was connected to the 802.11n network at 2.4GHz

    A friend has just done a quick test...
    Just did a quick test of changing the location, and sure enough 5GHz 802.11n is working. I changed it to Australia (from New Zealand), Network Utility says the network speed is 300Mb. I'll update my bug report with Apple with this info.

    It is interesting to see this in the system.log:
    Jul 21 01:02:58 My-MacBook-Pro kernel[0]: 11D beacon causing regdomain change to CC 36
    Jul 21 01:02:58 My-MacBook-Pro kernel[0]: en1: 802.11d country code set to 'AU'.

    Hi, I'm getting this same error "WirelessJoin unexpected status: 8", in the same circumstances described above. The only difference is, for me the solution David found of changing country to Australia (or to any other), from New Zealand has no affect. The same error occurs.

    Hardware is a MBP 2.16Ghz, and Airport Extreme. Both are fully patched.

    Anyone have any suggestions?

    Thanks.
