HOW TO: Change Cable Modem IP Addresses to CONTROLLED NUMBERS
Using Boomers method, I have found a way to KEEP GETTING the same IP addresses for each account I run on my Cable Modem with Wireless setup. By remembering the Random MAC address for which account youve changed the IP address for, you can re-apply the MAC after changing to another one and you will get the same IP address that was previously associated with it.

What you need to do is change the MAC ID for the ROUTER ONLY. The reason why people still get the same IP is because of this. The original MAC ID is located on the bottom of the router so there is no need to copy or write it down if you ever want to revert back to it later.
The first step is to connect your Ethernet cable from your computer to the router so they can communicate and adjust settings. You do not need to do anything with the cable modem at this time. It will be towards the end.
Open up IE (internet explorer) or Firefox and type in your router address, mine is 192.168.0.1 if you don't know it then look in your router manual or cd that came with your router. Or goto the Run command and type in "cmd" and the ipconfig/all and you will see you router address.
Enter your login name/password if you have it set, mine is "admin" which is default. Now the menus is different for each router company. Just find the option that says MAC ADDRESS and click on it or click on manual settings and you should see your MAC ADDRESS. It looks like 6 boxes with 12 numbers and letters in sets. For example 01-5d-b2-42-f1-65
Now you want to change the MAC ADDRESS by doing the following.
Leave the first box the same. You only have to change the other boxes with numbers from 0-9 and letters from a-f but keeping the letters and numbers in the same position and only changing the value for example 01-4b-c5-31-a3-45
After you have replace them click on save settings or apply settings.
You will lose internet connection at this time. Now the final step is to unplug your router and your cable modem for about a minute or so and plug it back in. give it couple minutes to initialize and check your ip at ipchicken.com
You now have a new IP address. Repeat the process to get a new IP address through your router.
| Save the MAC address to an excel file that you should have for your IP addresses used per account. When you change your MAC for another account, your IP address will change as well. Saving this will revert back to your other accounts IP address.
This has been done for about two weeks now and is still working flawlessly.
UPDATE: This fix works a good amount of time. The longer span of time between MAC changes, the more risk of not having the same IP as another computer could be assigned to it. The test was conducted on comcast with a wireless router. |
