Dell Vostro 3500 with Broadcom BCM4312 (as siba reports) accessing AP with WPA-PSK encryption enabled. AP is 2m away from notebook,directly visible.
Within first 1-2 mins after boot I get "bwn0: RX decryption attempted (old 0 keyidx 0x2)" errors at tty0. Pinging access point with 1000 packages gives 20% to 50% packet loss.
Loading Ubuntu LiveCD at the same conditions and installing offered 802.11 Linux STA driver gives 0% packet loss.
How-To-Repeat: grep -E "wlan|bwn" /boot/loader.conf
grep -E "wlan|bwn" /etc/rc.conf
ping 192.168.0.1 (AP address)
Over to maintainer(s).
The BCM4312 doesn't support 802.11n created by default. You juste have to
switch mode to 802.11b when creating virtual interface.
#ifconfig wlan create wlandev bwn0 mode 11b
