    Hello, my USB rtl8187B is detected as shown:

    bt:~# lsusb

    Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

    but when I try:
    bt:~# ifconfig wlan0 up

    i get:
    wlan0: ERROR while getting interface flags: No such device

    then when I try:

    bt:~# lsmod | grep mac80211

    I get nothing

    then I:
    bt:~# modprobe rtl8187

    and try again:
    bt:~# lsmod | grep mac80211
    mac80211 137884 1 rtl8187
    cfg80211 21384 2 rtl8187,mac80211

    Default Re: realtek rtl8187B not working

    got it working by upgrading kernel to 2.6.30.9

    now I would like to know if I'm using the MAC80211 driver, cause iwconfig outputs as follow:

    bt:~# iwconfig
    lo no wireless extensions.

    eth0 no wireless extensions.

    wmaster0 no wireless extensions.

    wlan3 IEEE 802.11bg ESSID:""

    Tx-Power=27 dBm

    ????????
