Hi,
I did the exercise to integrate all the drivers and tools in order to support USB WiFi dongles based on Realtek RTL8192CU/RTL8188CUS chipset.
It is working fine on my mangOH board with WP8548 running the firmware SWI9X15Y_07.05.01.00 (the one delivered with Legato 15.10).
My WiFi dongle used for the test is the famous Edimax EW-7811UN (based on RTL8188CUS).
If you want to test it, I have uploaded a Yocto image (kernel+rootfs) for WP85 target:
Yocto image (only for SWI9X15Y_07.05.01.00)
[color=#FF0000]Warning[/color]:
Prior to install this image, your mangOH board (WP8548 module) must be already upgraded to Legato 15.10 (firmware SWI9X15Y_07.05.01.00).
[color=#FF0000]Do not try to install it on top of another version.[/color]
Then, here is an example about how to use it:
