[-- Attachment #1 --] Hi Martin, I got similar problem from my PC using a Netgear WG311T PCI wireless card. ath0: <Atheros 5212> mem 0x40100000-0x4010ffff irq 11 at device 8.0 on pci1 ath0: AR2413 mac 7.9 RF2413 phy 4.5 I have joined all my config files, and the results of the commands : # dmesg # ifconfig # dhclient wlan0 Also, I have opened before your mail to the list, a thread on FreeBSD Forums http://forums.freebsd.org/showthread.php?t=16373 --- En date de : Mer 28.7.10, Martin <nakal@web.de> a écrit : > De: Martin <nakal@web.de> > Objet: ath(4) hostap with fake MAC/BSSID results in station dropping packets when associated > À: freebsd-stable@freebsd.org > Date: Mercredi 28 juillet 2010, 22h24 > > Hi, > > I noticed a bug that was introduced somewhere in the > Atheros 9280 > support in 8.1-RELEASE when used as a station.
