Wifijammer – Continuously jam all wifi clients and access points around you

everything is traceable.

I mean if I was going to do it, I would actually get a raspberry pi and either a board mounted wifi or a usb wifi adapter and then run this.

portable and away from something silly like you uploading a JPG with EXIF data to a server from the same MAC address.

Why not talk to the admins about doing off hours monkey wrench testing? Find the hotspots that become overloaded the quickest, lag statistics etc.
