All before having any manually installed drivers, my wireless card was not working properly and I decided to download and install Broadcom BCM43225 drivers. It was a hard process for such a newbie like me to understand that 'readme' file that comes with download to build a driver from source but I did it (woah such a long sentence).
I was able to use wireless as normal for a long time but somehow it's not successfully loaded on boot anymore (not sure when it stopped working).
I built the same driver from source just in case an update made a kernel-level change or something but it seems like every boot there is another clean-build required to get that driver working because trying to insert previously built module result with:
insmod wl.ko
Unknown symbol in module
I'm able to get it working with this bash script:
lspci -n | grep 14e4
cd /home/user/Belgeler/hybrid-v35_64-nodebug-pcoem-6_30_223_248
make clean
make
lsmod | grep "brcmsmac\|b43\|ssb\|bcma\|wl"
rmmod b43
rmmod brcmsmac
rmmod ssb
rmmod bcma
rmmod wl
modprobe lib80211
modprobe cfg80211
insmod wl.ko
for i in `find /lib /var -name wl\.ko`; do mv $i ${i}.orig; done
cp wl.ko /lib/modules/`uname -r`/kernel/drivers/net/wireless
Here is the output just in case you're interested in build messages and such:

Every reboot makes previous built driver to not work. I still have that modeprobe wl command in rc.local file and again it used work like a charm and still the driver itself works but I have no idea why I can't make them load on boot.
Edit:
Here is super-detailed-diagnostic wireless info created with this script. Alternatively, this output received before manually inserting wl module.
