Mike,
from what I can see in one of your earlier e-mails, you appear to be
dealing with BCM4311, which is in my experience one of least problematic
- worked out of the box on CentOS 6, however, ymmv. Anyway, it would be
useful if we could see the output of:
lspci -nn
just to confirm the exact Broadcom chip.
Now, the manual at CentOS wiki used to be sufficent to make the WiFi
work (as eth1 or wlan0, regardless - although I always configured it as
eth1), sadly, this is not entirely true anymore. To be more precise, the
latest driver from Broadcom site doesn't work at all on CentOS 5 (tested
it not a month ago with BCM4311). So, in order to avoid paying to
DriverGuide.com, I can either send you a older version of a driver, or
you can download one from here:
https://launchpad.net/ubuntu/maverick/+source/broadcom-sta/5.10.91.9.3-3
(I haven't tested the latter), and go through the installation manual
step by step. I haven't read Gytis' manual, but it should work in pretty
much the same was as the one on CentOS Broadcom Wiki - as he contributed
to the Wiki :-)
Hopefully, I'll perform some more testing soon and remedy obsoleted
parts of the Wiki page as soon as the time permits.
P.S:
And yes, you should leave NetworkManger manage your network connections
for start, and stop meddling with wpa_supplicant and manual wireless
configuration - it'll save you time and nervs.
So, just run:
service network stop
service NetworkManager start
chkconfig network off
chkconfig NetworkManager on
