When you try to build module from source with command “make all” and manually insert this module with “insmod” command, maybe you get this error:

[root@anif ~]# insmod wl.ko
insmod: error inserting ‘wl.ko’: -1 Unknown symbol in module

sometimes you also get error when run “modprobe” command after run “make all” and “make install”

[root@anif ~]# modprobe wl
FATAL: Module wl not found.

to fixed this problem, just run from gnome-terminal, command

depmod -a

before you run “insmod” or “modprobe” again.
