First, you will need to log into your router. If you’re unsure how to do this, follow these steps.

1. Open command prompt, on newer systems this can be done by typing in “cmd”  in the search box of the start bar.

2. Once it’s open type “ipconfig” without the quotes. Look for your Default Gateway. This will be the address to your router.

3.  Open your internet browser and type in the address. Example 192.168.1.1

4. Log in. If you’re unsure what your user name and password are, google the type of router you have. Linksys default is Admin and Admin for both fields. NETGEAR’s is adminf or the login and password for the password.

Next you will need to look for your MAC Address settings. In linksys it is usually labeled “MAC Address Clone” in the Setup tab. Each router is different, if you cannot find it by navigating menus, you may want to google your router along with the term “mac address” *Make sure you’re not in the wireless mac address settings*

1. Change the last two digits of your mac address.

An example Mac address would be 02-16-d3-66-a2-4b, so you would want to change 4b to something else. If the number is even, try to keep it even, if it’s odd, try to keep it odd.

A changed MAC address example would be 02-16-d3-66-a2-6b or 02-16-d3-66-a2-2d

2. Turn off and unplug your modem and router and wait 60 seconds

3. Turn your modem back on but keep the router powered off and wait for all the normal status lights to come on

4. Plug the router back in and wait for it to power up

Your IP should now be different, you can confirm by visiting whatsmyip.org before and after the process. If for some reason the process doesn’t work, try 2 different digits for the mac address and repeat.

 

If you aren’t behind a router you can change your IP with the IP Config function but this only works on certain ISPs. This can be achieved by doing the following:

1. Enter command prompt and type “ipconfig /release” without the quotes.

2. Enter your network and internet settings via the Windows Control Panel. Find your Local Area Connection. This is usually under “Change adapter settings” In Windows 7. Right click the one your internet uses and go to settings.

3. This will bring up a list, Locate “Internet Protocol Version 4 (TCP/IP v4) Click it once and then press the properties button. Instead of “Obtain IP automatically select manually and enter all 2’s.”  For subnet mask enter 255.0.0.0 then click ok.

4. Turn off your modem and wait  60 seconds, go back into the Internet Protocol settings and go back automatic settings and press ok.

5. Plug your modem back in and allow it to boot up.

6. Go back into command prompt and type “ipconfig /release” without the quotes

7. Wait a few seconds and type “ipconfig /renew” without the quotes.

 

This will depend on your ISP but will reset most IPs. There are similar write ups which don’t include turning the modem off, make sure you do this, or else the modem may hold the IP even though your pc has released it.
