I have my own wifi network at home & recently when I checked the active clients on the wifi I found out the there is one active client. Router shows the MAC address of this client and I want to Access this computer in order to let him know that he's doing a wrong thing. I dont intent to do any harm to his data. I just want to know a method to send him a message saying 'Buy you own wifi'.
Most WiFi router provides the features to add and connect the device to the network using the MAC address. Steps to be followed to configuration ( common to all WiFi routers) 1. This tutorial is about how to change Router MAC address into PC MAC address. If Your Internet service provider locks your mac address to your PC then you can't use it in your newly purchased Tp.
How can I achieve this using a windows 8 computer. Is there any specific softwares that I can use or will the netsend command do the trick!
Thank you.
Are you trying to add the MAC address for Access Control feature? The Access Control feature is added if you upgrade the firmware of your router to the latest firmware version 1.0.0.52. To upgrade the firmware of your router, see the instructions here. Let us know what happens. If you were, somehow, able to change your modem's MAC address, your ISP would no longer recognize your modem as being associated with you. You would be perceived as either a non-customer (e.g. A guy moves into a house and hooks up a modem without subscribing for service) or as another customer with the same MAC address. This will establish the router as your address the cable modem will set up as the main mac address. Then go ahead and boot up any other routers, and computers and wifi. That should keep everything connected because the router will delegate all the addresses to everything and the modem should remain 'happy' with the router addres.

Doing this is non trivial (read 'hard' if you don't know your way around networks).
The easiest way is to probably resolve the MAC address into an IP address (Using DHCP to statically assign dynamic IP's is one way of doing this longer term, if its a one off, looking at your routers ARP table or equivalent web page could do you).
You then need to intercept the request and push your own data back. The typical way this would be done would be to use some kind of tproxy and iptables rules along with a custom website.
This is the kind of thing which really needs to be done in the router.

If you want to send him the message only then there's a way.. But its very childish type... Whenever he is active on your network then just change the name of your hotspot name.. like 'BUY YOU OWN WI-FI' and then lock the mac addresss....

'I dont intent to do any harm to his data. I just want to know a method to send him a message saying 'Buy you own wifi'.
Do you think that you could be overestimating the capabilities of your computer system?
Talking about basics, you can only send the message to a machine with a successful receipt acknowledgment only if that computer is expecting to hear something from your machine?

Moreover, why don't you just close your wifi using a WPA2 password protection instead of changing the world?

How To Put Manual Mac Address Into Modem Account
Before you start your 'attack', you need to do some information gathering. Some of the information requires a tiny bit of math, and programming. Trivial stuff.
His MAC address is composed of 6 Bytes in hexadecimal format. You need to convert this from hex to a floating point, this can be done with the following equation: REDACTED
Once you have converted the MAC address, you need to subtract the number from the last octet of the IP address to get your memory offset. i.e: If the floating point is 122 and the IP address is 10.0.0.200, the resulting number would be 200-122=78
Once you have your memory offset, you will need to determine the terminal velocity of his modem. This can be done using a cryptographic injection of the isolation buffer. The steps to do this will differ depending on your operating system.
If you are running Windows XP or below, in a command prompt run the following:
inject.library.dll 10.0.0.200 --windows /unix On Windows 7 or Windows 7, the following can be used in Power Shell:
velocity.inject:::DLL internet 10.0.0.200 (buffer overflow) On Linux, the command is as follows:
for i > u ( inject.buffer command IP 10.0.0.200 )These commands should inject the modem buffer with the proper commands, and output the terminal velocity the modem is running at.
At this point, you will need to download a hacking tool such as ping, telnet, or ftp. You might need to try each tool because it depends on the operating system that his network is running. Generally, linksys network running cat5 are vulnerable to a ping attack, and netgear networks running cat6 are vulnerable to ftp attacks. Apple networks running wifi are vulnerable to telnet attacks.
Once you run your tools, you will be prompted to enter the memory offset to establish a connection. After you establish the connection, you will not have administrator access yet. You will need to send the terminal velocity that you identified earlier, and attach it to a neutral bogon assembly. This step can be tricky, but it's often times easier to just type the velocity in notepad and paste it over and over into the victims modem.
If the velocity attack is successful, you will know. Your desktop and icons might change, and this is an indication that you are in their computer. DON'T WORRY. They can't see what you are doing (this is the point of the memory buffer, remember). They see their windows, and you see yours. Once you are connected, you can browse their Facebook, play music through their speakers, and even start a fire by sending a bunch of sequential writes to their CPU.
Please note: This is provided that you are working in a test environment, or you are official sanctioned by the person or company to perform this penetration test. The rules and laws of your country apply, and I cannot be held responsible for the use of these hacking methods.

If you can access your router and check who's connecting and taking advantage of your internet connection, go to the settings tab of your router and find MAC address filtering or IP address filtering and put that person's data there and block it.
It should be simpler, or you could just change your password mixing small case and big case letters with symbols and numbers, so if somebody would try to hack it, they would lose the will to do so if they see a million years decoding time of their hacking software.

Tags: MAC Address
All network hardware is assigned a special unique identifier, the Media Access Control (MAC) address during production by its manufacturer. It helps identify the device on the network. Sometimes it is necessary to change that id and use a particular MAC address to be able to connect to your ISP. Below is a general guideline on how to do so on many routers/gateways and ADSL/VoIP/cable modems.
Here are the necessary steps to change the MAC address on your device:
1. Get to the web admin interface of your device.
You will have to find your router/modem's IP address. If you're connected to it, you can drop to command prompt and type: ipconfig (the IP address of your 'Default Gateway' should be the router/modem's IP). Some of the most common IPs are:
Motorola SB modems: 192.168.100.1
Other modems/routers: 192.168.1.1
You can also lookup the default IP and login information of your device in our hardware database.
2. Find the correct menu to change your MAC address
It is usually in 'Setup > Advanced', you're looking for a menu called 'MAC Address Clone'. This should let you enter your own MAC address, it is designed to clone the MAC address of your network card. Note that this menu may not be available on all devices, or it may only be available to be provisioned by your ISP. In such cases, you may have to call them and ask them to 'reprovision' your modem.
