Dell D630 hardware here, with Intel 3945 WiFi working only so so with wpi(4) driver.

I have WORKING WPA connection using wlan0 interface on wpi0 card using wpa_supplicant, but some things do not work (or work not so reliably).

0. My current configuration.

    
    # cat /boot/loader.conf
    if_wpi_load="YES"

    # cat /etc/wpa_supplicant.conf
    ctrl_interface=/var/run/wpa_supplicant
    ctrl_interface_group=wheel
    ap_scan=1

    network={
      ssid="wpanetwork"
      proto=WPA
      psk="wpapassword"
      }


    # ifconfig wlan0

PROBLEMS:

1. Networks scanning not working.

    # ifconfig wlan0 up scan
    wpi0: fatal firmware error
    wpi0: timeout resetting Rx ring
    microcode alive notification version 10e02 alive 1
    microcode alive notification version 10e02 alive 1


    # ifconfig wpi0 up scan
    ifconfig: unable to get scan results


    after that, connection no longer works and I need to restart these:

    # /etc/rc.d/netif restart
    # /etc/rc.d/wpa_supplicant restart


2. Need to wait to get connection

    After boot, or restarting netif/wpa_supplicant scripts I need to wait
    for about a minute to get connection back.


3. Messages displayed by kernel on /etc/rc.d/netif restart

    # /etc/rc.d/netif restart
    in_scrubprefix: deletion failed
    wpi0: need multicast update callback
    wpi_newstate: RUN -> INIT flags 0x0
    wlan0: link state changed to DOWN
    wlan0: Ethernet address: 00:1b:77:xx:xx:xx
    wpi0: timeout resetting Tx ring 1
    wpi0: timeout resetting Tx ring 3
    wpi0: timeout resetting Tx ring 4
    microcode alive notification version 10e02 alive 1
    microcode alive notification version 10e02 alive 1
    wpi_newstate: INIT -> SCAN flags 0x0


4. Messages displayed by kernel on /etc/rc.d/wpa_supplicant restart

    # /etc/rc.d/wpa_supplicant restart

    (after about a minute of silence)

    wpi_newstate: SCAN -> AUTH flags 0x0
    config chan 6 flags 8005 cck f ofdm 15
    wpi_newstate: AUTH -> ASSOC flags 0x0
    wpi_newstate: ASSOC -> RUN flags 0x0
    config chan 6 flags 8035
    wpi0: need multicast update callback
    wpi_newstate: RUN -> AUTH flags 0x0

    wpi_newstate: AUTH -> AUTH flags 0x0

    wpi_newstate: ASSOC -> RUN flags 0x0
    config chan 6 flags 8035
    wpi0: need multicast update callback
    wpi0: need multicast update callback

   (and I have working connection again)
