my network is being attacked by a program called udp flood. This program carries out an attack in Unidirectional wireless card, sending packets without waiting for an answer, consuming all the upload bandwidth.

Firewall Filter - does not work
AP TX and RX Limit - does not work

When the attack starts the wireless card UP-Load is an average of 5mbits, simply dropping the network and makes it very slow.

Striker clone the mac of a client connects to the network and starts the attack to the destination UDP 255,255,255,255 by 5000, or any other port

what is the solution to this problem? Without the need to encrypt the network
