Looks like rtlwifi, rtl8192cu driver code does not contain any calls to ieee80211_beacon_get() or ieee80211_beacon_get_tim() (except in pci.c) so I guess beacon frames are missing simply because that functionality was never programmed. (Realtek vendor driver does transmit beacon frames, though.) Colin
