    Angry Problem with wireless connection

    Hi,

    I`ve sumbled uppon the mos curious problem with my wireless networkj connection and I`ve spent the whole weekend try`ing to find some refference online to my problmem and/ r fix it but nothing.
    I`ve runed out of ideeas and I thounght some one could give me a hand.

    I have an Alfa AWUS036H wireless cart with ETK8187 Chipset and using RTL8187 driver on BT4 R1. This card is wlan0. It works perfectly in monitor mode .. injection and everything.

    BUt when I connect to a wireless AP .. cart in Managed mode .. it connects .. I can ping the network for a few seconds then PING replys with Destination host unreachable. Both iwconfig and ifconfig , as well as Wicd tell me I`m still connected but no traffic goes through. I`ve cheched everything from the local logs to the AP`s logs but I couldn`t find a couse of this.

    Code:
    root@bt:/pentest/passwords/wordlists# ping 192.168.1.1
    PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.

    BTW... this happens on any other AP ,, doesn`t matter what enc it uses ... the same thing happens for WPA2 WEP or OPEN APs ...
    I had this problem on BT4 final .. then updated my system to BT5 R1 ... same thing .. and I`ve tried on a different computer .. and location .. but with the same wireless card .... same thing.


    Any ideeas. no matter how crazy .. at this point I am willing to try anything
    Thank you.

    Well I must be doing something wrong here. I don't have a copy of BT5.
    As for the rest. There is a tutorial, and we do not condone testing on other people's access points.
