All examples are from an "old" RaspberryPi.
Are the needed kernel modules missing?

$ ls /boot/kernel/wlan* /boot/kernel/urtwn*                                    

/boot/kernel/urtwn-rtl8188eufw.ko       /boot/kernel/wlan_ccmp.ko
/boot/kernel/urtwn-rtl8192cfwT.ko       /boot/kernel/wlan_rssadapt.ko
/boot/kernel/urtwn-rtl8192cfwU.ko       /boot/kernel/wlan_tkip.ko
/boot/kernel/wlan.ko                    /boot/kernel/wlan_wep.ko
/boot/kernel/wlan_acl.ko                /boot/kernel/wlan_xauth.ko
/boot/kernel/wlan_amrr.ko
$ 

Or are they not loaded?

$ kldstat

If they are missing you have to build and install a new kernel with
a extended configuration.

In my old RPi kernel configuration I use in one line:

makeoptions     MODULES_OVERRIDE="wlan wlan_ccmp wlan_tkip wlan_wep
 wlan_amrr wlan_rssadapt wlan_xauth wlan_acl urtwn urtwnfw firmware"

I am unsure about the "MODULES_EXTRA" line. May be you should just add
the missing drivers there.
