    Exclamation Error setting monitor mode on wlan0

    Hi!

    I am using a Realtek Semiconductor Co., Ltd. RTL8180 wlan adaptor.

    aireplay is working well - i can fake-connect and inject.
    But i if i start airodump-ng i get the following error:

    Error setting monitor mode on wlan0

    somewhere in google i found the advice to try this:

    Code:
    Test #1
    switch-to-hostap
    then
    airodump-ng -w /tmp/test wlan0
    or
    airodump-ng -w /tmp/test wifi0
    
    Test #2
    do the same with the other driver
    switch-to-wlanng
    then
    airodump-ng -w /tmp/test wlan0
    or
    airodump-ng -w /tmp/test wifi0
    
    hope it helps
    but switch-to-hostap does not exist and i have no clue.
    If i start ubuntu dapper drake everything works well with patched drivers.

    Any advice?
    Yours sincerly

    Try the airmon-ng script!
    "\x74\x68\x65\x70\x72\x65\x7a\x39\x38";

    That's nonsense. Airodump works under ubuntu! And aireplay injection is also working well - i can fake-connect and inject. It's definitively a driver or config problem!

    I never said your card was bad, nor did I suggest that it was something other than a driver or config problem. But getting a supported card might be the easiest path to getting your programs working.

    Also Ubuntu and BT2 are two different flavors of Linux. Don't expect that just because your card works in Ubuntu it will automatically work with BT2.

    Thank you for your response and for your help. I am just a bit confused because
    HERE[1] and HERE[2] ist is quoted that the card is supported.

    Yours sincerly

    Choice #1 buy a new supported card- http://search.ebay.com/search/search...11t&category0=

    Choice #2 mess around with your shit for days trying to get it to work and the end result is_who knows

    I'm not trying to be a ass but in my opionion why not have a lot of cards that work for diferent pourposes. i have a vpn wire less card, a injection card ,what im saying is that $20 bucks on ebay is pretty cheap. dont give your self a head ache with the card. learning bt can be head ache enough at times

    I get the point.

    But if iam buying a new card, i'd prefer one with support for an external antenna.
    Can you recommend one?

    That answer is also right here.
