Just to clarify, what I mean by 'set up a distributed network' is just run a botnet using https://github.com/pirate/python-medusa/, that will let you run this little script on multiple computers all connected to the same Wifi.
I've tested it with a Linksys WRT54G, a Cisco router that I cant read the serial # on, and an Apple Airport Express. What router are you having trouble with?
Asus ac87u, just to be sure did you check it with another client because sending random junk to random targets will do absolutely squat to modern Wifi routers.
That however will definitely could kill your own interface or make the ap boot you for misbehaving.
With all 3 networks I tested it with (<20 clients each), it prevented other connected clients from sending/receiving packets while the flood was running. I will try it at my office next week and report back if it works with more powerful corporate APs.
