Chris Pirillo: How Can You Tell if Someone is Using Your Wi-Fi?

Do you have the sinking feeling that someone may be accessing your Wi-Fi, but don’t know how you can tell for sure that this is happening? Thanks to modern routers, you can usually find a list of mac addresses that have connected to it during its life span. This list will usually give you a general description of the device and their method for connecting. Once you’ve determined whether or not a malicious party has accessed your router, you can make a solid plan of action to lock it down.

  1. I’m an idiot and could never get the WPS2 password thing to work so I set my router to only allow specific MAC addresses. My network is listed as insecure and MAC addresses aren’t that hard to mimic but so far I haven’t found any usage outside what I’d expect on a particular day, e.g., my PS3’s MAC when my son is away at college.

  2. I don’t mean to be offensive here but show people how to use Mac filter on their routers, then deny mac addresses that are not in that list – obviously showing them how to find out what their mac addresses actually are. Even if anybody can figure out your password they won’t be able to use your connection.

  3. That was so informative, so is he saying that modern modems now have some kind of tv screen on them where it tells you what thingies are conected to it? I’ve never seen one of those anywhere, they’ve not come to my town where I live yet, that’s for sure.

  4. Good information but not presented very well.
    I think he was just winging it. Perhaps demo a way to view a log of the mac address from a router. Then a way to create a white list. I know all routers are not the same, but it would be a lot clearer to understand.

  5. What a total waste of time. And bandwidth. I STILL don’t know how I can tell if someone has been on thanks to this “non-explanation”. Total rubbish. Take a quaalude.
