    enable monitor mode

    I am currently running my wireless using the ipw2200 driver. I downloaded the source, whose documentation said that the driver could run in monitor mode (although it is not officially supported) I am still running with the original driver, which might be an earlier version.

    I want to switch to monitor mode. So far i have tried
    sudo iwconfig eth1 mode monitor
    which causes me to loose network connection and have Ubuntu automatically reconnect in managed mode.
    Any ideas?

    You have to suspend networkmanager, if you don't it will detect the drop in network connectivity caused by monitor mode, and then change back to managed mode, and reconnect.

    My ipw2200 won't monitor anymore, it stopped working with airmon-ng around ubuntu release 7.04.

    Looks like I lied, your command worked fine, I guess I shouldn't have been so lazy.
    I would kill networkmanager, and try again.

    I used:
    sudo airmon-ng start eth1
    Found 5 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!

    If a post is older than a year or so and hasn't had a new reply in that time, instead of replying to it, create a new thread. In the software world, a lot can change in a very short time, and doing things this way makes it more likely that you will find the best information. You may link to the original discussion in the new thread if you think it may be helpful.
