I was hoping that when I put my wireless network card in monitor mode, I will be able to sniff everything in my WLAN. But I was surprised to see that I can only sniff prob requests from other devices connected to the same AP as my laptop. Even though I have disabled any sort of encryption. Even when I disconnect and reconnect my android, I cannot see the association request.
Does this has to do with channels and frequencies??

The AP is acting like a switch does, in that it's controlling traffic between the wired and wireless sides which prevents your traffic sniffer from seeing other traffic. For more info, read the link I provided. – Ƭᴇcʜιᴇ007 – 2014-03-18T14:23:20.067
