Apart from your installation kit and all that’s inside it, you need to ensure that these necessary things are in your direct access for the activation of your spectrum internet.

  • You may have multiple coaxial cable outlets in your home like dining room, bedroom, kitchen, and anywhere. But the important thing is whichever outlet you chose, just make sure it’s working and have a complete connection at the backend.
  • Apart from that, you also need to make sure to have access to the power sockets near your coaxial cable outlet for both modem and router.
  • Lastly, a computer or any other device where you can connect your modem/router should also be there because you need to make configurations using that.

Setting Your Spectrum Compatible Modem and Router

Before proceeding with the activation process, you need to connect all your devices and power them up. Make sure that a proper connection is established between all your devices. To do that, follow these steps.

  2. Connect one end of the Coaxial Cable with the Coaxial Cable Outlet of your home and the other End with the modem.

  4. Connect the power cables of both modem and router. Wait for a few minutes and once all the lights become stable, it will give you a signal of stable connection to the Spectrum IPS.
  5. In some cases, the online Status light on your modem may keep blinking for several minutes, just wait for 10 to 15 minutes as max because usually, the modem updates its firmware version in this duration. Eventually, a stable Online status light on the modem will show up once the update is complete.
  6. Lastly, connect your computer or mobile with your router using the Wi-Fi connection details (SSID Password) mentioned at the back of your Router.

If you want to use the personalized SSID for your router, just open the settings of the router by entering or in your browser and enter the login details which you will typically find on the back of the router.

You can also activate your modem through a simple phone call if you are unaware of following the steps I described above. I utterly understand that if you are a non-tech guy or someone who is not interested in putting himself into a hassle, you may want to prefer a quick fix instead of going deep down the things.

Install Your Own Purchased Spectrum Approved Modem

Renting a modem and having it installed by a Spectrum technician is a better option when don’t bother with saving small bucks. But when it comes to making an informed decision in saving the dropping bucks, I suggest buying your own modem instead of renting the one for additional dollars per month.

This option gives you the flexibility of internet plan up-gradation in the later times as you may have purchased your own DOCSIS 3.1 modem which supports a lot more bandwidth and internet speed than the one Spectrum provides you on a rental basis. To activate such a modem, follow these simple steps:

  1. The process is pretty simple. First, open the modem activation page of Spectrum by typing in the browser.
  2. Enter the Spectrum Account number or Phone number, then enter the last 4 digits of your Social Security Number.
  3. Enter the address of the spectrum service area on the activation page and click next.
  4. Now call Spectrum customer support and tell them to activate your own modem. They may ask for the model of your modem along with its MAC address.
  5. Upon providing the required information to the customer support, they will guide you about the necessary steps and procedures to follow, and within no time, your modem will be approved and activated.

Modem MAC or CMAC Address

It might feel like an arduous task but don’t worry it is worth your time. Spending a few minutes setting up your modem will reward you by giving an uninterruptable and consistent internet service.

Why Spectrum Activation Code Not Working?

During the activation of either the rented modem or your modem, the Spectrum activation page asks you for the activation code. But that code sometimes does not work and keeps on giving the “incorrect code” error. It may happen due to multiple reasons which are as follows.

  • It can be a typo or human error and the entered code is incorrect.
  • Your keyboard might be missing some keys which enter the wrong or incomplete code.
  • The servers of spectrum internet may be down at that time and can’t authenticate the code.

Whatever situation happens, the best solution to make this activation code work is by contacting spectrum customer support, they will instantly figure out the matter and provide you with the resolution.

Pro Installation VS Self Installation – Which is Best for You?

The main aim of both ways is to make your internet connection work by completing the installation process. But in both methods, the difference really matters. Do you know what exactly the difference is and why should you consider it?

Well, the main difference between pro installation and self-installation of spectrum modem is that in Pro Installation you have nothing to do but just a simple quick call to Spectrum customer care and ask them for installation. A Spectrum representative will be at your doorstep according to the scheduled appointment and will make everything himself. All you need is to sit back and relax. But here is a con as well, you know what’s the catch here? You need to pay the installation fees of $49.99 to the spectrum agent for the installation and activation of your modem and internet service.

However, in the Self-Installation method, you will be at the leverage of saving your hard-earned bucks, but again there is no free lunch in the world. You must go through all the steps for the activation of your modem and internet which I have described above in complete detail. So, it’s all up to your decision which option you want to opt for. Time leverage or Money leverage, just make your choice according to your preference.
