Is there anyway to determine the number of connections to my router and how do I determine the IP address of everyone who is using my internet?

Like for example I want to check if someone was connected to my home network, that isn't one of my home computers

This is my router: Linksys by Cisco Wireless-N Home Router.

OK, Just got back to see your model was posted. I linked to the manual at the bottom.

Before you get started, if you don't know how to get into your router, you would open a command box and type in ipconfig and enter. Enter the gateway IP address into your web browser: The default username is blank with a password of admin. If it is the defaults, you should change this soon (see chapter 2 in your manual, which is only one page long).

A lot of these home routers do not let you see if someone is connected with a wire, but that is probably not of real concern, but rather, you want to see who is connected wirelessly.

The following info assumes that you have an idea what IP addresses you actually have on your network, and anything else could be an intruder.

First, one clue as to who is connected would be anyone with a DHCP address. You can see that on page 7 of your manual. If someone has set their IP address statically, it will not show in this list.

Second, the most important indicator that someone will be piggy-backing your wireless will be the "Wireless Client list". This is on page 15 of your manual.

Lastly, you can look at the logs. This is found on page 24 of your manual. You need to enable this feature, and how to do that is also on that page.

Here is your manual:

hey thanks, I'm stuck at your instruction in the second paragraph. could you help me with it, thanks superuser.com/questions/303398/… – Pacerier Jun 28 '11 at 13:50
@Pacerier That was just how to find your router...Do you already know how to connect to it? – KCotreau Jun 28 '11 at 13:53
I saw your new question, so paragraph two is not releveant...you know how to at least connect to it, even if you don't know the password. That was just about finding the IP address to put in the web browser. – KCotreau Jun 28 '11 at 13:59

First, input your default gateway IP into your browser. Then input your default username and password (or the default if you haven't changed it yet, which you should for security reasons.) Then you should get a log of all the devices on your network. If you see more devices than you know are using your network, someone is leeching. This way only gives you the MAC or physical address of the device, not the IP.

btw is it true to say the MAC or physical address is more powerful in the sense that that person can't change it anymore? – Pacerier Jun 28 '11 at 1:27
you can change the mac address on some devices. Its generally not done however. – Journeyman Geek Jun 28 '11 at 1:35
