If you have been thinking about changing your Internet service provider, you should first change your Comcast IP Address. Doing this is important for several reasons. If you change your Internet service, you will have a new IP Address, which means a new mailing address and new email address. You will also be requested to download and install new software or upgrades. You must carefully review the instructions given in the ‘router portion’ of your Comcast Internet Service Agreement and know exactly what your obligations are before you change your Internet service.
To change your Comcast IP Address, log onto your computer’s web browser and access’accounts’. On the ‘My Account’ page, scroll down to ‘Netgear Router’; you will see a section marked ‘routers’. Click on the link for ‘Change DNS Server’. Choose the desired name for your new IP Address and type the new information you entered. When prompted for entering your new information, make sure that you are entering it as accurately and precisely as you can.
It is imperative that you enter the new IP address exactly as it appears on your current router and on your screen. If you have entered an incorrect or outdated address, your ISP may deny your request for Internet access. Before you change your Comcast IP Address, you must backup your existing configuration. You will find this in your router’s control panel; you can also view it online by clicking on ‘dhclient’. Once your existing configuration has been backed up, simply change your Comcast IP Address by following the same steps above. You will also need to restart your computer.
However, if you have already changed your Internet connection provider, you need to change your Comcast IP address in accordance with your new service provider’s settings. For most providers, this involves updating the DNS settings on your modem. To change Comcast IP address, click on ‘My Account’ on the web browser and log on to your account; you will see a link to ‘Network Settings’ on the page. Click on this and select the ‘IP Changing’ tab. You will now see a page containing a field for entering a new IP address.
In the new window, click on the link for IP changing and input the new IP address where it appears on your screen. Be sure to enter numbers only after making confirmation of the number you are trying to enter (using quotation marks). The new address will now appear on your screen and you can change it by clicking on Save. Once you have saved the new setting, return to the ‘Network Settings’ page and click the radio button marked ‘IP Adresses’ to indicate that you wish to carry out this change.
If your router does not already have the feature, you will need to purchase a new one or request an addition. On the home page of your router, there is usually a selection labeled ‘ggeraintenance’, click on it. This will take you to a page where you can add a new IP address in addition to the ones you have listed. Follow the instructions printed on this page.
There are, however, more steps you can take. Go to the ‘IP Traffic’ setting. It is usually found in the main menu of your router (usually at the top). On this page, you will find the port that your modem uses for outgoing packets of information. You will notice a section labeled ‘Broadcasting’; this is the section where you will enter the IP addresses of your friends and family that are using the same wireless connection you are using.
When you click on the radio button of the type indicated, you will be prompted to enter the IP address of your modem, the port number you have selected for outgoing traffic, the SSID (stand by name) of your modem and also the password. Follow all the instructions on the page and save your changes. Restart your router, make sure that the settings are correct and you are then ready to test the settings again!
