    Default Ralink RT2870 vs RTL8187B

    Hello everybody

    my first post ... been around for a while ... in and out, since UUCP/UUPC and x25

    thanks for great OS

    Some of my experience with BT and Belkin Components F6D4050 N150 Enhanced Wireless Network Adapter v1000 [Ralink RT2870]

    I have Toshiba Satellite 310L with Realtek Semiconductor Corp. RTL8187B Wireless Adapter which works just great in everything.

    After few days ... and nights cant say the same about Ralink RT2870, but I'm totally new to BT. Some fix maybe near, but I did not getting it.

    OK here is what I have done;

    no such string as

    in airmon-ng

    no wlan0, no card, no driver - empty.

    Interface Chipset Driver


    Installing compat wireless

    root@bt:~# apt-get install linux-source

    Kernel Headers in BT4 R2 already there

    checking IW

    iw --version
    iw version 0.9.18

    already there

    checking firmware

    apt-get update && apt-get install firmware-ralink

    already OK

    that is much nicer in BT4 R2 compare to BT4 R1, everything already installed.

    after testing few compats I found that one, which installs fine without any errors


    make unload

    rtl8187 unloaded

    modprobe rt2800usb

    perfect no errors and nothing works

    Interface Chipset Driver


    after reboot sometime frozen completely after hardware interpretation: HALD

    then reinstall BT and all same again. did it few time already.
    any suggestions appreciated. not that really I care much about that card, but more about process itself.

    one more observation to add

    as result of installing compat-wireless - patched rtl8187 driver which comes with BT, been replaced with unpatched driver from compat-wireless and my card stack on one negative channel. there is a patch on aircarck for that problem. Instead of reinstalling compat I reinstalled BT.

    Is there any chance that the new Backtrack version to be released will support the Belkin F6D4050 N150 wireless card,version 1000,Ralink rt2870 chipset, out of the box?
    So that the necessary drivers comes with the iso of the new version?

    For now I only use Backtrack 4 R2 as a Live cd and other cards I have tested as Netgear vg111 v3 as well as Alfa Awus050Nh works out of the box.
