Question

I have a driver file wl.ko. How can I install it or where should I put it that my wifi works on my Asus 1018?

Network controller: Broadcom Corporation BCM4313 802.11b/g LP-PHY

Answer 1

Only load the kernel module if it was compiled for it. You can check that by running modinfo -F vermagic /path/to/wl.ko. It's output would look like:

2.6.35-28-generic SMP mod_unload modversions 

The 2.6.35-28-generic part is the kernel version for which the module was compiled. It should match the output of uname -r. If these versions do match, proceed. Otherwise, stop.

Before following the next steps, test whether the module would load:

modprobe -nv wl

If the module would load, it shows something like:

insmod /lib/modules/2.6.35-28-generic/kernel/net/wireless/wl.ko

1. Copy the module to the modules directory by running:

   sudo install -m 644 /lib/modules/$(uname -r)/kernel/net/wireless/wl.ko
   

2. Update the module dependencies map for all modules by running:

   sudo depmod -a
   

3. Load the kernel module in the current session:

   sudo modprobe wl
   

   If you get any errors, do not proceed, remove the module by running:

   sudo rm /lib/modules/$(uname -r)/kernel/net/wireless/wl.ko
   sudo depmod -a
   

4. Add wl to /etc/modules by running:

   echo wl | tee -a /etc/modules
   

5. Update your initial ramdisk with the kernel module by running:

   sudo update-initramfs -u
   

Answer 2

It goes in /lib/modules/<kernel-version>/kernel/net/wireless where is most likely 2.6.35-22-generic, to make sure of it do:

$ ls /lib/modules/

And see the highest entry there.

Make sure to make a modprobe wl after you got that file copied
