[noisette]

When connecting a Usb-to-Wifi adapter using Realtek chipset RTL8892CU, BeagleBone Black (Angstrom distribution 3.8.13) fails saying that the firmware rtl8892CU.bin is not available

Question for Koen: Would it be possible to package the firmware files with
Angstrom?

thx,

Hey, noisette, I followed the exact same steps, and I'm also getting "firmware is too big!" message

You mention you copied the wrong file? What was the correct file?
I copied rtl8192cufw.bin and I'm still getting that error. Do you remember how did you fix it?

( I'm using 8192, because that is what appears in lsusb )
I really need this, Thanks
