Unhappy Fedora cannot detect wireless card on HP pavilion (dv9502 au)


i have a HP Pavilion notebook (model dv9502au), and i want to make wireless internet work on Fedora...

this is the umpteenth time i have tried to install wireless card driver into fedora for my laptop...i have used fwcutter, ndiswrapper and the like, but without any success.

this is a jist of my latest attempt:

i downloaded the latest version of the broadcom wireless card driver from the hp website.

i also downloaded latest ndiswrapper source files, and installed it.

i then installed the driver using the ndiswrapper -i command.

the ndiswrapper -l command told me that the device was present.

i then executed : modprobe ndiswrapper

no output.

i then executed :dmesg | grep ndiswrapper and got the following:

i then executed : modprobe ndiswrapper

no output.
This is normal the driver loaded without an error, if you want to see something then add the verbose switch;

modprobe -v ndiswrapper

For the details see: man modprobe

what should i do to rectify this problem.....please help!!!!!
Sounds like you forgot to blacklist and remove the b43 and ssb drivers before installing the ndiswrapper module.

cat /proc/modules | grep b43

modprobe -r b43
modprobe -r ssb

Add to the /etc/modprobe.d/blacklist file at the end;

blacklist b43
blacklist ssb

Make sure that the /etc/modprobe.conf file has been edited for the b43 alias and ndiswapper alias.

# alias eth1 b43
alias wlan0 ndiswrapper

Also make sure you have the ifcfg-wlan0 file in the /etc/sysconfig/network-scripts directory.
