CentOs wifi not working Broadcom BCM43225
 

I switched from OpenSuse to CentOs 6, But it give a very hard time
after installation it does not installed the wifi driver BCM43225 for my acer aspire 5741, then i tried different solution on google but with no luck,
with this solution http://wiki.centos.org/HowTos/Laptop...om?action=show

i have an error at Step 3 i.e $ make -C /lib/modules/`uname -r`/build/ M=`pwd`

please help me as i want to switch to CentOs.... :(

Instead of attempting to compile the drivers yourself, maybe you could try the pre-compiled Broadcom wireless RPMs from http://atrpms.net.

Follow the instructions there to install atrpms and atrpm-repo RPMs, then simply use yum to install the Broadcom kernel modules:

yum install broadcom-wl-kmdl

This method has the big advantage of allowing new broadcom modules to be installed whenever a kernel update is released. The broadcom rpms from atrpms will be available within a few days of each kernel update, so you will want to wait until the new broadcom modules are ready before updating your kernel, but it sure beats having to re-compile and re-install every time a new kernel is released.

ITS GIVING ME ERROR AS "error: too few arguments to function ‘strnlen’"
SUGGEST ME A SOLUTION FOR THIS PROBLEM.

int apnlength;
u_char apn_name[]="LTE";
struct sockaddr_in ggsn,sgsn;
apnlength = strnlen(apn_name);
