I was trying to make two routers communicate with monitor VAP. But I failed several times. It seems that if there 's only a monitor mode VAP, it recieves all packets in the air but cannot send any out. It is strange that if I start up the monitor VAP with an adhoc VAP, the monitor VAP can send packets and the two routers communicated well. but, it's not stable. And i can not start up an ap mode VAP at the same time.So it's not what I want. I just have the question that is it possible for a monitor mode Vap to send packets? if it can, how to? Ps,I am using an ar5213a wireless card on the Asus wl500w router. Thanks for everyone's help. SunKnight |
