I am running FC2 test 1 and I cannot get the Broadcom WiFi to work.

I installed everything and it is detected but, I just can't get online.

so my question is how do you troubleshoot a WiFi connection.

I have disabled the firewall, cleared the iptables and tried it but, i get no connection.

Any help will be appreciated

Here is more information

when I type
# iwconfig wlan0

I get

Warning: Driver for device wlan0 has been compiled with version 16
of Wireless Extension, while this program is using version 15.
Some things may be broken...

when I type
# iwconfig wlan0 essid any
to retrieve any available network name, I get a name assigned to essid as "tsunami"

and when I type
# ifconfig wlan0 up

The WiFi is up but, I still cannot connect online.
Do I need to set up an "ifcfg-wlan0"?

I am having this exact same error/problem in Suse9. Please let me know if you find a resolution.

Grateful.

Okay after some hair pulling and skull cracking and some , I finally got it to work.

I went to ndiswrapper's site and downloaded the cvs ndiswrapper - basically it is version 5 + cvs.

but anyway, open a Konsole and type

$ cvs -dserver:anonymous@cvs.sourceforge.net:/cvsroot/ndiswrapper login

When prompted for a password for anonymous, simply press the Enter key

$ cvs -z3 -dserver:anonymous@cvs.sourceforge.net:/cvsroot/ndiswrapper co ndiswrapper

This is the cvs website instruction ndiswrapper cvs

It will download the cvs ndiswrapper to a file callled ndiswrapper

If you have installed a previous ndiswrapper, uninstall it by running "make clean" in that directory

and you can leave the alias entry in "/etc/modprobe.conf" and the ndiswrapper directory "/etc/ndiswrapper/bcmwl5"

I created an file in "/etc/sysconfig/network-scripts/" called ifcfg-wlan0 and this is what it contains

DEVICE=wlan0
BOOTPROTO=dhcp
ONBOOT=no
MODE=Managed
ESSID=any

Basically I want dhcp to automatically detect and configure wlan0.

Go to the ndiswrapper directory as root and somewhat follow the instructions
# make install
# ndiswrapper -i /etc/ndiswrapper/bcmwl5/bcmwl5.inf
--- this is the directory for the inf from the previous install of ndiswrapper-0.5

# ndiswrapper -l
-- make sure it says "bcmwl5 present" because I had to try almost three different drivers and I settled on the emachine driver.

# modprobe ndiswrapper

# dmesg --you will see a log about the driver been loaded if you do
then

# ndiswrapper -m

# iwconfig -- to make sure you device is recognized

and finally
# ifup wlan0

Some modification my be necessary so read the "INSTALL" documentation that came with ndiswrapper.

Finally I must say Kudos to the developers at ndiswrapper
