I know I have used it successfully in the past but it may have been with a different (ath) card and I don't know what FreeBSD version it was so I can't be much help in determining when it stopped working (if indeed it ever did for this hardware). The machine in question currently has an AR9220 card: ath0: <Atheros 9220> mem 0xfebf0000-0xfebfffff irq 20 at device 5.0 on pci4 [ath] enabling AN_TOP2_FIXUP ath0: [HT] enabling HT modes ath0: [HT] 2 RX streams; 2 TX streams ath0: Enabling register serialisation ath0: AR9220 mac 128.2 RF5133 phy 13.0 ath0@pci0:4:5:0: class=0x028000 card=0x2096168c chip=0x0029168c rev=0x01 hdr=0x00 vendor = 'Atheros Communications Inc.' device = 'AR922X Wireless Network Adapter' >How-To-Repeat: ifconfig wlan0 create wlandev ath0 wlanmode hostap bssid ifconfig wlan1 create wlandev ath0 wlanmode hostap bssid ifconfig ath0 ifconfig wlan0 ifconfig wlan1 notice that the MAC addresses of both vap's are identical to the parent device. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
