Who is connected to my wifi?

Question

Hello,
I would like to know how I can find out if my neighbor is connected to my Wi-Fi?
One day, I gave him my password so he could connect while setting up his ADSL contract, but I would like to know if he is still using my network today or if he has indeed completed his ADSL contract?
I can't change my password because it would be embarrassing if he realizes I'm doing this because of him... he's a good friend!
I just want to know, for now, if he's connecting to my ADSL network or not.
I have Windows 7, a Wi-Fi router, an HP laptop, and my iPhone is also connected to my Wi-Fi network.

Thank you for your help

Configuration: Windows 7 / Internet Explorer 9.0

Hello,

It is very easy to find out who is connected to your box. First, type 192.168.1.1 into your browser's address bar.

Once you reach the box menu, look for the list of devices connected to the box. You will have a list concerning phones, laptops, and other connected devices, indicating next to them whether they are connected via modem or Wi-Fi, as well as their MAC address and the name of the device in question. (notably if it says PC-of-your-friend, for example)

I could go further to approximately find the distance of the connected device, but that is sufficient.

I think this will help you.

Hello,what kind of box do you have to connect to the Internet?On some boxes, a light blinks to indicate that the internet connection is in use.

Well, in any case, I use it! The question is whether anyone else is using it! I don't live in France, so it's a local company... a box with flashing lights, yes...

The most efficient thing would be to plug in a cable and disable the Wi-Fi, and if your neighbor asks you, just say your access is down ;)

But is there no software method to know, for example, the number of computers on my network?
For instance, if I see there are more than 2 (my computer + my phone), it means someone else is connecting to it...

But what will you do if you discover that he is using it?

Well, I will change the password in that case.

but how to connect to my box?!

regcal · Answer

With an RJ45 cable, you enter your box's IP address into your web browser.

oulala looool I don't know anything about computers, could you please explain it to me a bit more easily hehehehe thank you very much!!

regcal · Answer

You plug a cable into your box, open your browser, enter the IP address, and you'll access your box's options.

regcal · Answer

The IP that Michael gave you.

smickaels · Answer

Sorry Antoine, I indeed didn't see your response! Before entering the IP address, do I need to connect the box to my computer?

smickaels · Answer

When I enter the IP address, I am asked for a username and password, where can I find this information?!

regcal · Answer

Hello, I use this software Nirsoft Wireless http://www.nirsoft.net/utils/wnetwatcher_setup.exe  found here http://www.nirsoft.net/utils/wireless_network_watcher.html

smickaels · Answer

I entered the username and password, but nothing happens, the computer is just "thinking"...

What happens is that the password I enter disappears, the computer is "thinking", and during this endless time, I cannot use the browser.

In the end, if I close the small window, the unauthorized 401 message appears!
