yo instale

$ dpkg -i Downloads/firmware-atheros_0.36+wheezy.1_all.deb

y me reconocio la tarjeta de red luego segui esta guia

y no me funciono

http://enchufado.com/post.php?ID=341

https://wiki.debian.org/es/Compartir_red_fisica_con_WiFi

estos son los programas que necesitaras para que te funcione , que esta en la siguiente

$ apt-get install hostapd dnsmasq

$ service hostapd stop
$ service dnsmasq stop
$ update-rc.d hostapd disable
$ update-rc.d dnsmasq disable

esta si me funciono

# Specify range of IP addresses for DHCP leasses

no se te olvide cambiar en start.sh a ppp0 a eth0 y si estas en debian wheezy reemplazar la palabra sudo por vacio en definitiva el start.sh quedaria

Ejecutar start.sh como root

start.sh

#!/bin/bash

# Start

ifconfig wlan0 192.168.150.1

# Start DHCP/DNS server

service dnsmasq restart

# Enable NAT

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

# Run access point daemon

hostapd /etc/hostapd.conf

# Stop

# Disable NAT

iptables -D POSTROUTING -t nat -o eth0 -j MASQUERADE

# Disable routing

sysctl net.ipv4.ip_forward=0

# Disable DHCP/DNS server

service dnsmasq stop
