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'.
