I have used "WIFI Kill" since I got a Droid X years back and it is pretty useful for kicking people off the internet. Dont like 25 kids sitting around being obnoxious just for the free wifi? fire this up and watch them leave :)
 
I will upload two versions for different android versions. Im not sure which will work for yours, please dont ask. You'll have to try them and see.


I have used both of these on multiple phones but feel free to test them in a vm or sandbox or however you feel like testing it, VT detects malicious programs and your virus scan may also when you download it but these are false positives as far as im aware
As always if you like my stuff please leave me a like.
