Re: Hostapd failed with USB WiFi dongle (RTL8188CUS 802.11n)

[yertnam...@gmail.com]

I'm having the same problem.  I've got a TP-Link WN823N which is supposed to have the RTL8192cu chipset which sounds like it is supported by BBB.  I was all excited when I was able to compile hostapd from the realtek sources, but still no dice.

I am using below setup on BeagleBone Black board with Realtek USB WiFi Dongle RTL8188CUS. Same setup as my Raspberry Pi.

But this will cause below error. Any one can help this? Thanks!

Do you have you wifi card on wlan1 interface?

Also, you can try driver + hostapd from Realtek website:

http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true

It works for me.

I have a question, when you use Realtek USB WiFi Dongle RTL8188CUS,  server is BBB or your PC?

Hi,

I setup ad hoc wifi with RTL8188CUS by following adafruit tutorial (step by step but adapting RTL chip version): 

https://learn.adafruit.com/setting-up-a-raspberry-pi-as-a-wifi-access-point/overview

If you use udhcp, you need to disable some part of /opt/scripts/boot/am335x_evm.sh relative to udhcp, and you lost ethernet via USB
