Hi,
I'm still reading about this topic as I see it is often a problem of late getting wireless to work.
Here is a helpful
how-to.
Always first check which wireless you are using with command:
lspci
it is usually the last entry.
In Pardus, one way to get it to work is add an entry to the file:
/etc/modules.autoload.d/kernel-2.6
as explained
here. If "wl" doesn't work, then try "b43" instead. Reboot. I've been looking over both Pardus Turkish forums and thanks to their suggestions on this topic, they've gotten many folks' wireless to work.
Another thing to check is if you have Windows installed, boot into it and make sure the wireless switch is on, then reboot into Linux. Some people have it turned off in Windows which effects Linux not being able to see connection.

I need to try this out on the iMac as it has an airport extreme card with wireless firmware version: Broadcom BCM43xx 1.0 (4.170.46.9), the infamous b43.
Thanks for posting this! A week ago I had Pardus installed and tried many things to try to get my Broadcom 43225 to work, but I failed, and I gave up and installed Ubuntu for the time being. I got accepted into this forum, so I really hope I can get my problems worked out because Pardus seems like an amazing distro. I tried these steps that you suggested, but they did not fix my problem.
Any suggestions?
Thank you!
