Hi, my name's Dave Andrews. Today, I'm going to tell you how to tell if your wireless router has been hacked. Let's go to our computer. And in most cases, you can access your home router by going to the address bar and typing in Now, I use a Linksys router, and the user name to log into that is admin. And by default, the password is going to be admin as well if you haven't changed it. Now, I've changed mine, so I'm going to type in my new password here. Now, for Linksys, of course, it's admin and admin, and you can find that in your router's manual. I'd suggest if it's still admin that you change that to something a little more secure. Now, once you've logged into your router, it's a good idea to go to the Wireless tab. And I clicked on the Wireless MAC filter button here under Wireless, and what I'm going to do is I'm going to scroll down a little bit until I see a button that allows me to access my wireless client list. So I'm just going to click that. And that pulls up a pop-up window that shows me all of the clients that are currently accessing my wireless router. And as you can see, there are three currently connected, basically, IPs is how I can tell them, and each IP has a MAC address assigned. Now, you should only really see the number of devices that you have that are capable of accessing your wireless. Now, I know that I'm allowing three objects because I have a laptop, I have another laptop, and I have a cell phone which is capable of logging onto my wireless router. So these three, I'm pretty confident, belong to me. Now, if you see more than the number of objects that you have that are capable of accessing your router -- say, there were five or six here -- I would know that somebody other than my devices has logged on and gotten an IP address from my router. Therefore, they're able to use the Internet using my connection. So I'm going to close this. One way to prevent this is to create a MAC filter. Now, on your each of your computers, if you go to the Start button, you go to the command prompt, you run it as an administrator, if you type ipconfig/all, you're going to find in here, somewhere, the hardware address for your network device. There is mine right there. That's the Ethernet, so I need the wireless. I'll scroll up a little more. Here's my wireless LAN, and there's the physical address. It's a series of letters and numbers. You're able to filter out those by MAC, and that will allow you to control what devices are able to access your wireless router. My name's Dave Andrews, and I've just told you how to see if your wireless router has been hacked.
