“No Network Devices Available” for BCM43241(SDIO) after fresh install of 13.10
Found in the question, written by the OP.
After contacted a developer of broadcom, he gave me mails between him and an user who had same issue but have successfully solved this. The user helped me by sending another nvram and firmware (a bin and a txt) and it worked. I think it's just because the wireless card is too new for the current kernel (correct me if I say something wrong as a novice of linux).
I attach them here

copy them to /lib/firmware/brcm and execute sudo modprobe brcmfmac-sdio, the problem solved.
