How to Stop People From Using Your WIFI Using Cmd





Introduction: How to Stop People From Using Your WIFI Using Cmd

In this instructable, I'm going to teach you how to stop people from hogging your WIFI using cmd. This can be used if they are watching Youtube, Netflix, or doing other Bandwith activities while you are trying to watch Youtube, Netflix, play online games, etc. and you want them to stop. Or if you really just hate someone.

Step 1: Finding Your Router's IP

First, open cmd. If you don't know how to do this, hold the Windows Key + R, type "cmd" in the box that comes up, and then hit enter or type "cmd" in the search box. Type "ipconfig" into cmd then hit enter. If you are using wifi find your wifi adapter and if you are using ethernet, then find your ethernet adapter. Next, find the IP listed under default gateway. This is your WIFI router's IP. Copy it down. Mine is This is a common IP for a router.

Step 2: Go to Your Router's Webpage and Find the IP of the Device You Want to Kick

Now go to your internet browser. In the address bar type the IP we just found. Most routers come with a default username and password needed to log on. To find your default username and password go to Once you are logged in, find where your connected devices are displayed. Mine are in a section on the home page. Then find the IP of the person you want to kick. I will demonstrate this on my phone. It is named "robyn-HP" and it's IP is "" (Yes I know that doesn't sound like a phone's name, but I have it named like that for a separate reason)

Step 3: Creating the Program

Next, create a new text document. I have an editor named Notepad++ Which isn't required, but it is a better alternative to the standard notepad. In that text document, type "@echo off" and then "ping (THE IP YOU FOUND) -t -l 65500" as shown in the photo. So for me, I would type "ping -t -l 65500". This will be our kicking device. Save this as a .bat file by clicking save and typing ".bat" after your file name as shown in the photo.

Step 4: Running the Program

Lastly, run the .bat file as quickly as you can about 20 or so times. If you have a better computer you can do more. Now, sit back and wait. DON'T CLOSE THE PROGRAMS.

Step 5: Seeing the Affect

In the first photo, I took a speed test before I started the programs. My phone got a download of 20 MB/s and upload of 12 MB/s. In the next photo, I did a speed test just 15 seconds after I started the programs. It then had a download of 11 MB/s and upload of 6 MB/s. In the last photo, I did a speed test about 4 minutes after I started the programs. It showed a download of 0.5 MB/s and upload of 0.9 MB/s. At that speed, the person will be wasting their time, and will probably stop using your wifi because it is now useless to them. Thank you, and have a great day!

    I noticed that your router has the ability to use parental controls you might look into using that and just set the users IP address in a set time frame that they can use it, I've done it many times
    but nice instructable

    What your are describing here is a Denial of Service (DoS) attack, and it won't work the way you've described.

    This process might annoy the target, but since you are launching the attack from a single source, both the source and the target will be subject to the exact same symptoms. This means your connection will be slowed just as much as theirs.

    Since this attack will not disconnect the target, you're stuck maintaining the attack continually to annoy the target, which will mean you suffer the entire time.

    Instead, if you have access to your router, consider seeing if your router can boot the target device. Or setup or change your wifi security to cut off the target's access.

    In short, this is a terrible way to accomplish your task.

    Agreed! Being in security I was hoping someone would be smart enough to know this! Not only are you hurting yourself the same amount, but ICMP (ping) requests usually are either not accepted or ignored after like 100 from a target in a certain period of time. Just, foolish...

    If you don't like this instructable, you don't have to use it

    This is not meant to permanently kick someone as described on step 1. It's meant to discourage them from doing what their doing whether that's YouTube, Netflix, ect. So you can do what you want to do with good speeds, and get peace and quiet

    Just to quick nit pick about MB vs Mb....they are not interchangeable. A 12 MB/s isn't the same as 12 Mb/s and besides, network speed is almost always measured in Mb/s. That's all.

    While you're at your routers interface, change the default password so no one else can look it up and log in.

    That's a good idea, I'll add that in as soon as i can

    Lots of routers don't have QOS. If you'd rather use that, go ahead

    Truthfully I'd just ask the person not to hog the bandwidth since is not acceptable at a place of work, not sure where this would be useful.

    Rude brothers and sisters, friends that you regret giving the password to, ect
