Hi,

Try the aufs way mentioned here

> [@How to build RTL8192CU/RTL8188CU drivers for MangOH?](http://mangoh.discourse.group/t/how-to-build-rtl8192cu-rtl8188cu-drivers-for-mangoh/272/17):

> If you failed to copy your .bin file under directory /lib/firmware, here is the alternnative way: Go to directory /mnt/flash -2. mkdir lib/rtlwifi, so you will see directory: /mnt/flash/lib/rtlwifi copy the binary file rtl8192cufw.bin to /mnt/flash/lib/rtlwifi -4. run: mount -t aufs -o dirs=/mnt/flash/lib=rw:/lib=ro aufs /lib Install your driver module. So the driver at this time will try to load firmware binary from /mnt/flash/lib/rtlwifi/rtl8192cufw\_TMSC.bin or rtl8192cufw.bin
