    Default Re: No wireless internet connection

    At first, do you have a VMware or native installation?

    Next which chipset?

    What's the result of lsusb? Is your device showing up?
    I have a native installation. Chipset is Intel 855PM. lsusb:

    Bus 004 Device 001: ID ld6b:0001 Linux Foundation 1.1 root hub
    Bus 003 Device 001: ID ld6b:0001 Linux Foundation 1.1 root hub
    Bus 002 Device 001: ID ld6b:0001 Linux Foundation 1.1 root hub
    Bus 001 Device 001: ID ld6b:0002 Linux Foundation 2.0 root hub

    Well, No USB device is detected (if any), and it detects something in eth0, which can be your ethernet wired device and the eth1 if any, should be the wifi card...
    Type iwconfig and post result...Also type "lsmod" and "lspci"...Look for the intel xxx...Perhaps your card is not supported by BT5...As far as I know, ipw2100, 2200 and 3915 are supported...I'm not sure about the 855PM chipset.

    here is an output of my lspci (which stands for "list pci" or list pci devices) so that you can see what you should be looking at:

    I underlined the important info so you can see that my linux is detecting the wifi card.

    Here is an output of lsmod (List Modules loaded by kernel or device drivers if you are used to work with winbugs): lsmod | grep ieee
    ieee80211_crypt_wep 11776 1
    ieee80211 38344 1 ipw2200
    ieee80211_crypt 13444 2 ieee80211_crypt_wep,ieee80211

    ieee1394 94660 1 ohci1394
    I underlined the important info you want to check, in my case kernel loaded ipw2200 drivers, because in the intel home page, the linux drivers are the same for ipw2200 and 3915...
    So I can see that is just correct.

    Try this and check what is the kernel loading and what is detecting..Check the Intel page and look for the linux drivers for that chipset, so you can download it in case you have to install them in BT5....

    Best of lucks..

    Please help!
    I have intel centrino wireless card on my dell and i have internet on backtrack 5, but airmon-ng start wlan0 won't work
    I have tried evrything, but nothing helps.
    Can someone help me please?
    greetz


    root@bt:~# airmon-ng start wlan0


    Found 3 processes that could cause trouble.
    If airodump-ng, aireplay-ng or airtun-ng stops working after
    a short period of time, you may want to kill (some of) them!

    PID Name
    1481 dhclient3
