Hi,  
There are several topics on setting up USB Wi-Fi dongles with Realtek chips, but those instructions are not working for me.  
When I try to load module rtl8192cu i get this:

```auto
[41.372226] rtlwifi: Unable to register rtl_rc, use default RC !!
[41.378910] rtl_usb: Unknown symbol ieee80211_rx (err 0)

```

I’ve seen someone here with the same error, but I couldn’t find how to fix this.  
Thanks.

Hi @chebykin,

you’re probably talking about [WLAN USB adapter to MangOH - #5 by vincelai520](http://forum.legato.io/t/wlan-usb-adapter-to-mangoh/179/5) ?

Can you try to load mac80211.ko manually before that?  
Seems like ieee80211\_rx should be provided by mac80211.ko.

What does `lsmod` return?

Maybe my kernel configuration is incorrect?  
I have:

```auto
CONFIG_MAC80211=m
CONFIG_MAC80211_HAS_RC=y
CONFIG_MAC80211_RC_MINSTREL=y
CONFIG_MAC80211_RC_MINSTREL_HT=y
CONFIG_MAC80211_RC_DEFAULT_MINSTREL=y
CONFIG_MAC80211_RC_DEFAULT="minstrel_ht"
CONFIG_RTL8192CU=m
CONFIG_RTLWIFI=m
CONFIG_RTLWIFI_DEBUG=y
CONFIG_RTL8192C_COMMON=m
CONFIG_WIRELESS_EXT=y
CONFIG_WEXT_CORE=y
CONFIG_WEXT_PROC=y
CONFIG_WEXT_PRIV=y
CONFIG_CFG80211_WEXT=y
CONFIG_MAC80211_LEDS=y
CONFIG_RFKILL_LEDS=y

```

Do you have working configuration?
