Comment (by [EMAIL PROTECTED]):
I too have the same problem. I have a macbook. Here is the information
that I have gotten out of OS X - they don't have a /proc so I don't know
how to get it to tell me anything more...

Wireless Card Type: AirPort Extreme (0x168C, 0x86)

On the same machine, I am running Ubuntu Edgy:

It displays half the connection strength that is displayed in OS X. Even
when the computer is touching the wireless router, I cannot get a full
strength signal. Looking in proc, it seems that it is trying to use
channel two, like the cases above. Additionally, were the Mac takes a
second or two to establish a connection, running Linux, it can take up to
a minute. And some connections with low signal strength that can be
established with the Mac cannot be seen or connected to with linux.
Here is information from the /proc output:
Diversity : 1
Debug : 0
fftxqmin : 3
rxantenna : 2
txantenna : 0
Let me know if I can provide you with more information. I am trying to
figure out all of this, so be patient with me! ;)
