title: Why can't I view traffic on other devices using WireShark
body: <p>I'm running WireShark on the latest version of Ubuntu and I can't seem to be able to capture traffic coming from other devices besides my own. I see a TON of SSDP packets but not much of anything else. Also, I notice that a lot of the packets seem to be encrypted because they have mostly characters that don't mean anything in them. I am positive that I have Promiscuous Mode turned on. Can anyone help with this? I just would like to see decrypted traffic on other devices (my Nexus tablet in particular). </p>
  
  <p>Edit: I can see IP addresses of other devices, however I can't see any TCP packets for them. Only SSDP</p>
